The two-stage worm gear reducer can be installed in two ways: horizontal reducer and vertical reducer. The horizontal reducer can be divided into two-stage worm gear stop type and bottom mounted type, and its transmission ratio is generally 1/10~1/80. When the peripheral speed of two-stage worm gear reducer is less than 4m/s, the worm is usually in the lower form. When the circumferential speed of the worm is greater than 4m/s, it usually appears at the top in the form of a worm. When the worm goes down, the oil level should be lower than the root of the worm thread and not exceed the lowest...

Non standard reducers are generally used in special fields and occupations. The wheelbase between some input shafts and output shafts needs to be increased. Since the output shaft is equipped with a drum, if the wheelbase is not good, it cannot be placed. In this way, the reducer with larger center distance needs to be welded to the box as non-standard.  In some occasions with high ambient temperature and lots of dust, general users do not allow the reducer to add any cooling methods, including shaft fans, water cooling equipment, etc. In this way, they can only increase the reducer box or add...

The main differences between worm gear reducer and gear reducer are as follows:Different application scales1. Worm gear reducer: reducer is widely used in organizations used to transmit power and motion.  2. Gear reducer: widely used in metallurgy, mining, hoisting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.Different functions1. Worm gear reducer: increase the output torque by reducing the speed, and the torque output proportion shall be based on the motor output multiplied by the reduction ratio, but it shall not...

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...

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...

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...

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...

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,...

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 ...

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...

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....

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...
