Development of Cylindrical Gear Reducer

From the 1970s to the present, with the development of metallurgy, mining, chemical industry and other industries, the production industry has higher and higher requirements for the performance of equipment, further expanding the production scale of major production industries and greatly improving the degree of automation .At the same time, the required noise has been reduced, which puts forward high requirements such as high load capacity, high service life and low noise, which promotes the development and new development of reduced motors.In the late 1970s, China began to develop general hard tooth surface gear reduction motors, completed the design of standard products in early 1986, and formulated a new generation of reduced motor standards represented by cylindrical gear reducers.
Development of Cylindrical Gear Reducer
Today, after more than 30 years of improvement and promotion, cylindrical gear motors are widely used in mechanical transmission in various industries, which improves the level of basic parts and complete sets of products in China's machinery manufacturing.At the same time, due to the improvement of China's production level, the performance of lighten motor products has reached the current advanced level.
After years of development, although the series of cylindrical geared motors have been improved, there are still some problems, such as small series spectrum, insufficient coverage, poor box interchangeability, long production preparation cycle, conical cylindrical geared geared motors and many imperfections in the product.
The reduction motor series can be divided into two categories: cylindrical geared motors and bevel geared motors, installed horizontally, but can be extended to vertical installation.
The characteristics of the modular geared motor continue to adopt the carburizing crushing and fire grinding gear hard tooth surface gear technology, which retains the advantages of the cylindrical geared motor, such as high load capacity.In addition, it also has the following characteristics: adopting modular design, adopting optimal design, the nominal mechanical power of the reduction machine is 15% higher than that of ZBJ19004 reduction motor on average.Reasonable choice.
The structural design of the new geared motor improves the thermal power reduction of the motor.The carrying capacity of the hard tooth surface reduction motor is mainly limited by its power.Since the new geared motor adopts a square frame and a two-stage geared motor, and borrows a three-stage body, the body of the single geared motor is wider than the original mechanism, and the thermoelectric power can be increased by 20% using ZBJ19004 in the same specification.
