  • Factors of oil leakage at high-speed shaft and low-speed shaft of reducer

    2022-09-22
    First, the seal ring is worn and invalid. After long-term friction on the coaxial surface of the oil seal lip, it is easy to trigger the lip burn and carbonization, lose the flexibility and elasticity of the rubber, and become hard and worn, thus forming a gap when the oil seal lip is in coaxial contact.In addition, axial interference connection is required for both high-speed and low-speed shafts of the shaft coupler. During heating and installation, problems of oil seal heat transmission and radiation will occur, which will lead to early deterioration and deformation;Secondly, the shaft...

  • How to improve the service life of reducer

    2022-09-22
    All friends who have been in contact with the reducer know that the service life of the reducer is determined by the size of external load and internal wear rate. Too much load on the inside and outside of the reducer may cause tooth fracture, shaft fracture and wear of moving parts, while the wear of moving parts may cause difficulties in the formation of smooth oil film. Therefore, under the condition that the reducer has been assembled and hard tooth surface gears are used, the methods for improving its service life are as follows:I It is to avoid excessive external load on the components...

  • What is the relationship between motor and reducer

    2022-09-22
    The reduction motor refers to the integration of the reducer and the motor (motor). This integration can also be called gear motor or gear motor. Generally, professional reducer manufacturers provide complete sets of reducer and motor after integrated assembly.1) Reduce the speed and increase the output torque at the same time. The torque output ratio shall be based on the motor output multiplying/decelerating ratio, but it shall not exceed the rated torque of the reducer.2) Speed reduction reduces the inertia of the load at the same time, which is the square of the reduction ratio. You can...

  • How to maintain the reducer

    2022-09-15
    1. Transmission inspection The reducer shall be inspected and repaired regularly. Effective measures must be taken in case of scratches, gluing and significant wear. The spare parts must be manufactured according to the standards, and the updated spare parts can be officially used only after running in and load commissioning.2. The oil quantity and temperature shall be checked frequently. If the oil level of the reducer is lower than the lower scale mark of the vernier, oil shall be replenished in time. Pay attention to the change of oil pressure for circulating oil lubrication. When the oil...

  • Adjustment of spindle rotation accuracy of planetary reducer

    2022-09-15
    If the machining error of the spindle itself meets the requirements, the rotation accuracy of the reducer spindle is generally determined by the bearing. The key to adjust the spindle rotation accuracy is to adjust the bearing clearance.Maintaining a proper bearing clearance is critical to the performance of spindle components and bearing life. For rolling bearings, when there is a large clearance, it will not only concentrate the load on the rolling body in the force direction, but also produce serious stress concentration at the contact of the inner and outer race raceways of the bearing,...

  • Measuring method for gear clearance of gear reducer

    2022-09-15
    The tooth thickness (actual) dimension of the pinion and big gear of the gear reducer and the center distance dimension of the shaft plus the deviation of the corresponding gear elements determine the backlash j of the gear teeth, that is, the clearance between the non working tooth surfaces at the working diameter.There are two methods to detect the gear clearance of gear reducer:The gear shall be installed according to the service conditions (the center distance in actual use), and one of the fixed gears cannot rotate.Method 1: Use a feeler gauge to plug the tooth profile clearance from the ...

  • How to prevent the reducer from rusting

    2022-09-08
    As the reducer is mostly made of steel, if you don't pay attention to maintenance during use, the machinery will be easily oxidized and rusted after a long time, which will greatly reduce its service life. Therefore, we can take the following measures to prevent its rusting.1. The rust of the reducer is mainly caused by the presence of oxygen and water in the lubricating oil. The corrosion is caused by the acid and sulfide in the oil. We can add anti rust additives and preservative additives to the oil to avoid rust.2. Inject lubricating oil into the friction surface between moving parts to...

  • Difference between precision planetary reducer and ordinary gear reducer

    2022-09-08
    Precision planetary gear reducer is composed of planetary gear, sun gear and internal gear ring. It is widely used in various products with high torque and low rotation speed, such as case lock and electric clamp. What are the differences between precision planetary gear reducer and ordinary gear reducer? Here's a brief introduction.Compared with the ordinary reducer, the precision planetary reducer has higher rigidity, higher precision, transmission efficiency (up to 98%) and higher torque. It is generally connected with a micromotor for reducing speed, lifting torque and matching inertia....

  • Limit operating temperature of direct axis reducer

    2022-09-08
    I believe everyone has heard of temperature rise. Temperature rise refers to the temperature difference with the environment, which is generally caused by heating caused by long-term operation. Temperature rise is an important indicator in the operation process, which can clearly know the heating degree of the reducer in use. In operation, if the temperature of the direct axis reducer has reached the limit operating temperature of 50 ℃, it means that there is a fault inside the reducer, the vent is blocked, or the reducer has been overloaded.If the temperature generated by the operation of...

  • Analysis on the cause of shaft breaking caused by the non concentric reducer

    2022-08-31
    Some users have broken the output shaft of the drive motor after several months of operation. After checking the cross section of the output shaft of the drive motor, it is found that the cross section is almost the same as that of the output shaft of the reducer. The outer ring of the cross-section is brighter, and the color of the cross-section is darker toward the axis. Finally, it is broken at the axis. This fully explains that the main reason for the broken shaft of the output shaft of the drive motor is that the motor and the reducer are not concentric when assembled.When the...

  • Why should the motor be used with the reducer?

    2022-08-31
    The reducer is actually a power transmission mechanism, which does not generate power. Its function is to reduce the rotation number of the motor (motor) to the desired rotation number by using different gear sizes and speed converters, and obtain a larger torque. Isn't it enough to adjust the speed of the motor? In fact, the motor is directly connected to the equipment. When the equipment is running, the load on the motor is very large, which will cause great damage to the motor. However, it is not the same when passing through the reducer. For example, the reducer with a reduction ratio of 1...

  • Relevant standards for oil filling of reducer

    2022-08-31
    After the new reducer is put into operation for the first time, drain the oil in the tank and fill the new oil to the center line of the oil window. When refueling the gear reducer placed horizontally without oil window, remove the observation cover at the upper end of the reducer and insert the dipstick vertically into the bottom of the box (the dipstick is vertical to the bottom of the box). The oil level is 55mm-65mm; It is forbidden to mix new and old oil.For the gear reducer (e.g. granulation process in the first workshop) placed obliquely during the weekly inspection and monthly...
