FRC Kicks Off 2015

Triangle has been a sponsor and supplier of the FIRST Robotics Competition (FRC) for over 6 years. We were excited to hear about this year's theme:

The theme of the 2015 FRC is RECYCLE RUSH, a recycling-focused game played by two alliances of three robots each. Robots score points by stacking totes on scoring platforms, capping those stacks with recycling containers, and properly disposing of pool noodles, representing litter. In keeping with the recycling theme of the game, all game pieces used are reusable or recyclable by teams in their home locations or by FIRST at the end of the season. via

Triangle Manufacturing Partners with Robur for High-Efficiency HVAC Solutions

Triangle Manufacturing is proud to partner with Robur, who offers one of the most advanced solutions in HVAC, using up to 40% of renewable energy. Robur, an Italian manufacturer of heat pump heating and cooling systems and Triangle, a Wisconsin-based manufacturer of motor mounting brackets have partnered together to create capable systems for Europe's stricter high-efficiency standards.

Environmentally friendly and highly efficient, Robur units are ideal for heating multi-family houses, industrial buildings and commercial facilities. Robur units permit a considerable promotion of the building's energy classification. Robur utilizes Triangle's motor mounting brackets in their heat-pump line. These mounts are designed with sturdiness and strength for heavy duty vibration suppression and are adaptable to efficient assembling. Robur uses Triangle's TS arms, which are custom designed for use in direct drive blowers and fans. Triangle's arms are available with three or four arms and are galvanized for corrosion-resistance.

Robur chose a fan with a large blade because of new European regulations that began in 2013 to reduce the electric consumption of the motors (ErP 2013). Robur decided to modify their existing fan assembly in order to be compliant with this new European standard.

Due to the large pitch of the new fan, a new motor mount had to be designed to provide the necessary clearance for the fan while keeping the fan motor shaft as short as possible. Triangle responded with custom designed motor mounts with much larger curved arms than previous versions utilized. This deeper curve was a direct result of the extra-large fan blades and led to a complete re-design of the motor mounts.

Robur chose to keep the existing mounting system because they've had positive feedback throughout their more than twenty years of business with Triangle. The new, slightly different blade was a great project for Triangle to modify and adjust the mounting system to fit with the new layout.

Triangle and Robotics

Check out the below infographic from Kuka Robotics. Triangle has a similar story with the use of robotics. We have automated many processes in the last 5 years and instead of leading to job loss they've led to increased wages and responsibilities, along with less injuries. We automate when it makes sense, leads to increased efficiency and increased safety. (View it larger here.)

From Oshkosh to Dallas: AHR Expo Review

At the end of January Triangle exhibited at our first trade show. We ventured down to Dallas, Texas for the AHR Expo. We unveiled some new branding, seen below.


We sought to show the value of Triangle's service and products in an easy to understand, but interesting way. Our booth can be seen below, we featured our motor mounts, cushioned bearings, tri-arm brackets and even had a demo assembly fixture.

Part of the trade show team.


The show was full of characters, lots of customers and exhibitors and terrible food - par for the course for a trade show.


The 2013 AHR Expo set 2 new attendance records for Shows held in the Southwest:

  • Total Visitors – 33,891 (not including Exhibitor personnel)
  • Total Attendance – 51,337 (including exhibitor personnel)

The 2013 Exposition has also set two new Southwestern Records for size:

  • Exhibiting Companies – 1,953
  • Total square feet of exhibits – 396,564

All in all a great show!

Triangle Excited to Sponsor the FRC

Triangle is excited to sponsor the FIRST Robotics Challenge again this year. 

Check out our FIRST page here for product info. Triangle donated parts to both the Kit of Parts and the FIRST Choice aspects of the FRC.

The below article discusses Kick-Off and Oshkosh's local Wave Robotics Team.

Bright and early last Saturday morning students, parents and mentors convened at Fox Valley Technical College in Oshkosh to anxiously await the announcement of the FIRST® Robotics Competition's 2013 game. In a darkened room over 100 people associated with the local FIRST® team, Wave Robotics, watched the projector screen for hints of this year's challenge. The FIRST® organization first went over the benefits of involvement: fun, scholarship opportunities and college entrance and then finally announced it, "Ultimate Ascent".

Rumbles emanated from the crowd as scenes of Frisbee-throwing robots and pyramids appeared on screen. "This is gonna be interesting!" exclaimed parents. The students were shown the Ultimate Ascent playing field and received a Kit of Parts made up of motors, batteries, a control system, a PC, and a mix of automation components – with no instructions.

Within minutes of the announcement mentors and students were already buzzing around laptops and in groups talking about alignment and aerodynamics. The game is played by two competing alliances on a flat, 27 x 54 foot field. Each Alliance consists of three robots, and they compete to score as many discs into their goals as they can during a two-minute and fifteen-second match. The higher the goal in which the disc is scored, the more points the Alliance receives.

The match ends with robots attempting to climb up pyramids located near the middle of the field. Each robot earns points based on how high it climbs. The Wave team has never built a robot designed to climb or aim and throw Frisbees. Jake Fischer, a mentor who works at Oshkosh Corporation, said he was totally surprised by the challenge. "Throwing a Frisbee has never been attempted in the FIRST® arena. Conceptually and mechanically it will be the most difficult challenge to date." He continued, laughing, "humans routinely struggle with throwing Frisbees well and we have to do it with a robot in only six weeks." Student Ashuinraj Karthikeyan, a junior at Oshkosh North was surprised by the game's complexity and was concerned about having less control with an increased number of variables within the game.

Micheal Lau, a third year Wave Participant from Oshkosh West,said that the biggest challenges Wave faced was the climbing aspect. He said that over the last few years the team has learned a lot, especially to expedite game piece collection, and he hopes to use that experience this year to deal with trying to pick the Frisbees up quickly. There was a lot of nervous excitement during Kick-Off and it was obvious that the students and mentors have a lot of work ahead of them in the next few weeks.

From the FIRST press release: "Working with adult Mentors, students have six weeks to design, build, program, and test their robots to meet the season’s engineering challenge. Once these young inventors create a robot, their teams will participate in 77 Regional competitions with over 2550 other high schools. Competitions measure the effectiveness of each robot, the power of collaboration, and the determination of students." Wave will be competing at the Northern Lights Regional in Duluth, MN and will be returning to the Wisconsin Regional held at the US Cellular Arena in Milwaukee, WI in March where they will be looking to capture a regional win for the third straight year. Winning a regional event will qualify Wave to compete at the World Championships with 400 other high schools in St. Louis, MO at the Edward Jones Dome, home of the St. Louis Rams. Although the Wave team will have to build a complete robot that can climb and throw Frisbees in only six short weeks, Lau wasn't nervous. "Wave is a 'powerhouse team', we're good at game strategy and are constantly evolving", he said with a smile.

Watch the team's Facebook page and for the team's progress throughout the build and competition season. Wave Robotics is possible through the generosity, donations and time of parents, mentors, volunteers and area businesses.


FIRST Robotics Competition (FRC) is the one of four FIRST programs that help students to discover the excitement of science, technology, engineering, and math (STEM) and the rewards a career in STEM can bring. Approximately 51,000 high-school students from 16 countries will participate in the 2013 FRC competition.

Why Plain Spherical Bearings?

For many applications, they are a cost-effective alternative to roller and ball bearings.


A plain bearing weighs half that of a similar-sized, needle or roller bearing.


Roller or needle bearings can be hundreds of times more expensive than a plain bearing. This is due to their complex design and multi-component system. Added to the increased tooling cost, plain bearings are the cost-effective alternative.


Plain bearings have a larger surface area than rolling-element bearings. Engineers can use space saving smaller plain bearings that can accommodate similar, and sometimes even heavier loads than roller or needle bearings.


A reduced amount of parts and a simpler overall design means fewer components to break and need repair and lowered maintenance requirements.


Plain bearings have a higher load-spreading capability over roller or needle bearings and better withstand shock loads and can tolerate misalignment.


Plain bearings, even when slightly misaligned do not concentrate loads on balls or rollers but distribute them consistently and evenly. they accommodate small changes in pressure.
