Introduction Of Shimpo Servo Gearbox

1.Introduction of Shimpo

Nidec’s SHIMPO reducer uses helical gears. Compared with conventional spur gears, the connection between the teeth is smoother, thereby reducing noise.
Nidec SHIMPO was born in Kyoto in 1952 as Japan’s initial “variable reducer” manufacturer. Since then, after technical training, it has continuously developed new technologies and new products, and established a world leading position in the field of traction technology. I received three awards from the Japan Machinery Association and several invention awards, which fully proved my SHIMPO’s technical level.

Now use the latest production equipment and Japan’s quality management system to establish the world’s most advanced metal processing factory. The newly built factory produces many products (reducer for servo motor, stepless speed changer, measuring instrument and electric pottery machine).

Mute
10% less noise than previous products
Due to the use of helical gears, the connection between the teeth is smoother than conventional spur gears, thereby reducing noise.
Smoothness
Less vibration and smoother vibration-free rotation. It can play a role in places where drugs focus on injections and medical pumps.
The helical gear corresponds to the ABCD column of the VR series and all the columns of the EV series.
No maintenance & free installation
The lubricating oil adopts long-life high-grade grease, so there is no need to exchange it.
Moreover, it adopts a sealed filling structure, which can be installed freely.
Lightweight and compact with a weight of 550g and a total length of 99.5mm. (VR series)
A compact design designed for increasingly miniaturized and lightweight servo motors. (For 110W)

3. Features of Shimpo products

3.1 An ultra-quiet reducer that has never been seen before. Use helical gears to replace the previous spur gears. Compared with previous products, the noise is reduced by 10%;
3.2 High-precision, low-backlash series products with backlash below 0.05o (3 points). This reducer can accurately position and fully demonstrate the performance of high-precision servo motors;
3.3 Smooth rotation with low pulsation. The use of helical gears achieves smooth rotation with low pulsation. It is very suitable for products such as drug filling equipment and medical pumps;
3.4 The advantage of 22mm (when the D segment is 750W) is based on the lightweight design required by the designer. The corner size is 98mm (120mm of the same model of other companies). Miniaturized design. Effectively correspond to the ever-lightweight and miniaturized servo motors;
3.5 The assembly environment is excellent, and high-quality products are provided. Assembled in a clean room, the assembly environment is good, and high-quality products can be provided;
3.6 Maintenance-free & installation freedom. High-grade lubricating oil with long service life, no need to replace. At the same time, the closed filling structure is adopted, and the installation direction is free;
3.7 Perfect anti-oil leakage countermeasures. Implement the impregnation treatment of the shell, air leakage test, etc., and take perfect anti-oil leakage countermeasures;
3.8 Equivalent to IP65 waterproof requirements. Take waterproof measures to give full play to the performance of the reducer in any environment.
