2021年的飞跃奖（工程成就计划领导）的获奖者在本周在数码仪式上宣布，产品跨越多个类别，包括机械。
Critical to LEAP’s success is the involvement of the engineering community. WTWH Media was not involved in the selection of the winners. Instead, this year’s winners were chosen by an independent judging panel of 12 engineering and academic professionals.
In the Mechanical category, the winning submissions are:

Brecoroll Timing Belts
布雷戈柔性CO. L.L.C. is rolling into the future with an innovative timing belt that reduces slider bed friction in material handling applications. It’s called BRECOroll。布雷戈roll有尼龙辊集成到正时皮带的牙齿中，使其能够通过高精度同步带的所有效率滚到滑块床上，以及传统系统的摩擦力的一部分。如果您希望减少驱动能量和摩擦，特别是在长期跨越的较重的物体时，布雷孔rollis the ideal solution. BRECOrollbecame available for distribution in the spring of 2021.
本产品的理想应用
布雷戈rollis the ideal solution for any material handling application where the product load is bearing down on the slider bed causing or drag/friction resulting in belt wear and stress on the motor. The belt is designed for loads up to 6kg [13.2 lbs] per 40mm of belt length.
Typically, timing belts used for material handling tasks are very long. The belt’s load side usually lies in a support rail which causes friction. BRECOroll为滑块摩擦提供解决方案。这种新的创新在轴上的滚轮集成在皮带齿中。这些滚轮用轧制摩擦更换滑动摩擦，导致皮带和电动机上的压力较小。
布雷戈rollcharacteristics include:
- Replaces sliding friction with rolling friction of approximately half the value (μ <0.2)
- Maximum recommended speeds up to 1 m/s (3.28ft/s)
- Load-bearing capacity of 6kg [13.2 lbs] per 40mm of belt length
- Rollers are located on every other tooth (every 40mm along the belt length)
布雷戈roll优点包括：
- 由于减少摩擦和热量，较长的皮带寿命
- Smaller motor possible due to reduced friction forces
- 整体降低能耗
- 节省带更换和驱动维护的停机费用
- Can accommodate backings and profiles
开发过程和创新参与发展
The starting point for the development of BRECOrollwas the desire to create a solution that improves upon the existing timing belt when transporting objects and to do so in the most structurally simple way. Simultaneously, it needed to provide a potential for effective support of the tooth profile side of a timing belt. The desired outcome as shown in the attached image was to incorporate a rolling element into the tooth that can support the timing belt on the guide rails of the conveyor systems and prevent oscillations during starting and stopping. In turn, it reduces friction, heat, and stress to the belt as well as the motor.
While developing the concept of replacing slider friction with rolling friction, other considerations were taken into account such as adding rollers or roller bearings to the guide rails. However, in the case of timing belts, you need to avoid tooth engagement impacts. Therefore, either a lot of narrow support rollers would have to be arranged in the guide rails offset across the width so that each tooth profile is always supported by a support roller; or smooth, toothless longitudinal tracks would have to be provided on the timing belts in which multiple (at least two) narrow support rollers, similar to roller-bearings, extend across the width and ensure support. Both possibilities are, however, expensive and burdened by technical compromises. BRECOrollwas the most logical and cost-effective solution.
这个同步带代表的创新和设计是前所未有的。结果相当于皮带和驱动马达的寿命上的成本节省，以及由于维修和更换的停机时间不太可能增加产量。

IKO CRBTF交叉滚子轴承
IKO CRBTF超薄横梁轴承以几种方式在Iko的交叉滚子轴承技术的先进开发上建立：
-Super slim design, just 5mm wide
内部和外圈上的孔提供易于安装
随着其纤薄的设计，CRBTF解决了机器人臂和联合应用的复杂问题。它不仅提供高刚性和准确性，它可以适合较小的空间，并且还可以降低设备的尺寸和重量，因为不需要额外的安装板来安装。具有先进的机器人应用变得越来越小，CRBTF解决了可靠性和精度的尺寸和空间问题。
CRBTF was designed and developed to help in the fields of small robots and rotary stages. As these fields continue to advance in technology, there is a growing demand for small and high rigidity bearings.
The compact design of this bearing with an ultra-slim 5mm width contributes to down-sizing. The CRBTF provides an easy assembling process using the mounting holes provided instead of the time-consuming process of press-fitting. The use of CRBTF also reduces the number of required parts generally required for a press-fit mounting style such as housings or pressure plates which in turn helps with weight reduction of the device.

人类导致有意制动在Cobot轴上滑动。保持制动器也用作扭矩限制器，允许在紧的扭矩窗口内滑动。
制动器和机械扭矩限制器组合COBOTS
Ogura的新开发的MCNB-TSP制动系列具有非常精确和精确的保持扭矩。相同的制动器也能够在给定的扭矩下短暂滑动，对生命的影响可忽略不计。基本上，将其作为机械扭矩限制器和电磁制动器引入。扭矩限制能力在这种情况下增加了可以提高的安全性，并且可以设计周围部件以降低负载。利益是，系统重量可能会降低，导致更高的生产速度以及更长的电池和制动寿命，提高质量和吞吐量。
The brake series has a very thin profile, which is what cobot/robot manufacturers require. Torque is high for the given size and weight. Power requirement is low based on optimized flux paths and utilization of over-excitation and PWM power control.
To create this solution, Ogura had to rely on its experience, manufacturing knowledge, and R&D department. In fact, an entirely new proprietary material had to be developed. Many different materials were tested along the way. Surfaces finishes were also scrutinized for the highest consistency and repeatability. From a mechanical perspective, new spring types were evaluated for optimal performance, pressure, and torque control under spring compression. This cutting-edge development helps Ogura lead the way on a global scale while providing product solutions at an acceptable market price. It also puts the pressure back on cobot and robot designers to rethink how they design and manufacture their equipment given this new brake/torque limiter functionality.
