Gear reducers are becoming increasingly popular due to their longer service life and economic characteristics
The normal operation of the gear reducer is restricted and has had a serious impact on the gear reducer system. The key to fully utilizing the function of gear reducers is to improve their firepower. We usually improve the firepower of the gear reducer by cooling the gear reducer system. Jin Changcheng informs everyone that under normal conditions, the methods for increasing the rated cooling of gear reducers mainly include cooling fans, water-cooled coils, and several methods for external lubrication. The principle and technology of gear reducers When equipped with servo specialized gear reducers, high positioning accuracy (accuracy) is required under normal conditions. In addition to being able to accept large loads, servo gear reducers can also achieve particularly high transmission accuracy, with output end backlash accuracy reaching less than 1 point (imported SEW, PSF small series).

Servo gear reducers are becoming increasingly popular due to their long service life and economic characteristics. The servo reducer is the weight of the gear transmission installation of the servo reducer, and the weight of the Liyi electromechanical gear under normal conditions is closely related to its data and heat treatment hardness. In the application of servo control, it has good servo stiffness effect and positioning control. It has medium to low clearance, high efficiency, high input speed, high input torque, smooth operation, low operating platform noise, and a lightweight and compact appearance and structural design.
Widely used in industries such as precision machining machine tools, aerospace industry, semiconductor equipment, printing machinery equipment, food packaging, automation industry, industrial robots, inspection, precision testing instruments, and automated high-precision electromechanical products (Products). It has high-performance characteristics, and the following advantages make it perform well. The servo gear reducer has many advantages due to its small size, wide deceleration range, high transmission efficiency, and high accuracy. It is widely used in servo, stepper, DC and other transmission systems in the mechanical industry. However, we should pay attention to concentricity during the assembly and application of servo gear reducers. If the concentricity deviation is too large, it is easy to form the risk of shaft breakage.
1、 Reason Analysis 1. Lack of smooth oil; When the smooth oil level is insufficient or cannot reach a reasonable height due to gearbox oil leakage, it may cause high temperature or noise in the bearing area of the gearbox; 2. Friction of bearing covers or seals. If the bearing device is incorrect, the bearing cover is incorrect, or the bearing is worn out during long-term use, the temperature of the gearbox bearing is high or there is noise; 3. Damaged or worn bearings. The main content of this item is the damage to the bearing bracket, the wear or deformation of the inner and outer rings, and the wear or scattering of the ball bearings, which can cause the gearbox to not work properly;
4. The bearing clearance is too large or too small. When the gap between the reducer bearing ball and the inner and outer rings, the gap between the bearing inner ring and the shaft, and the gap between the bearing and the end cover increase, long-term use may cause the above-mentioned symptoms; 5. The handle of the helical gear key is loose. Loose helical gear key handle can cause gear and shaft to loosen, causing bearing overheating or noise; What kind of smooth oil is used for the reducer? 1. Horizontal cycloidal reducers use a smooth oil pool under normal conditions, and the oil surface height should be maintained in the middle of the sight glass. In harsh working conditions and high temperatures, circular smoothing can be used.
