In view of the problem of wear, the traditional solution is to repair welding or brush plating machining repair, but both have some disadvantages: repair welding high temperature thermal stress can not be completely eliminated, easy to cause material damage, resulting in parts bending or fracture;And the brush coating thickness limit, easy to flake, and the above two methods are metal repair metal, can not change the "hard to hard" with the relationship, in the comprehensive action of the forces, will still cause wear again.For some large bearings is unable to field solution

As for the leakage problem, the traditional method needs to remove and open the high torque planetary gearbox, replace the sealing gasket or apply sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again in the operation.

high torque planetary gearbox in the long-term operation, often appear wear, leakage and other failures, the main several are:

1. Wear of the bearing chamber of the high torque planetary gearbox, including wear of the shell bearing box, the bearing chamber of the box's inner hole and the bearing chamber of the gearbox

2, high torque planetary gearbox gear shaft diameter wear, the main wear parts in the shaft head, keyway, etc

3. Bearing position of transmission shaft of high torque planetary gearbox is worn

4. The combination surface of the high torque planetary gearbox is leaking

Key points of selection

high torque planetary gearbox is the most important type of high torque planetary gearbox matching servo motor, in the selection of high torque planetary gearbox, first to determine the high torque planetary gearbox reduction ratio, if the standard high torque planetary gearbox does not have the reduction ratio you need, please choose a close or customized high torque planetary gearbox.

After the deceleration ratio is determined, multiply the rated torque of the servo motor you selected by the deceleration ratio to obtain a value that is in principle less than the rated output torque of the similar high torque planetary gearbox provided in the product record, and also take into consideration the overload capacity of the drive motor and the maximum operating torque required in practice.The maximum operating torque required shall be injected into 2 bits of rated output torque.After satisfying the above conditions, please choose the high torque planetary gearbox with the smallest volume. The high torque planetary gearbox with small volume has a relatively low cost.

Then consider the return clearance of the high torque planetary gearbox.The smaller the return clearance, the higher the accuracy and the higher the cost.The user has to choose a series of planetary gearbox that meet their accuracy requirements.Also consider transverse/radial forces and average life.Lateral/radial force high torque planetary gearbox in the installation and use of high reliability, not easy to go wrong.Generally, the average life of the servo motor is much longer than that of the servo motor.

high torque planetary gearbox: the main transmission structure is: planetary wheel, sun wheel, outer gear ring.

Due to structural reasons, the single-stage deceleration is at least 3, and the maximum is generally less than 10. The common deceleration ratio is 3.4.5.6.8.10. The reduction series of the high torque planetary gearbox is generally less than 3, but some of the large deceleration has 4 stages of deceleration compared with the customized high torque planetary gearbox.

Compared with other reduction gear, planetary reduction gear has high rigidity, high precision (single stage can achieve less than 1 point), high transmission efficiency (single stage in 97-98%), high torque/volume ratio, life maintenance free features.

high torque planetary gearbox rated input speed up to 18000 RPM (about high torque planetary gearbox itself size, high torque planetary gearbox, the greater the rated input speed, the smaller) above, industrial-grade high torque planetary gearbox output torque is generally not more than 2000 nm, special large torque can be done in machine of decelerate of planet of more than 10000 nm. Working temperature in 25 ℃ to 100 ℃ or so, by changing the grease can change its working temperature.

Series: the number of sets of planetary gears. Since one set of planetary gears cannot meet the requirements of a larger transmission ratio, sometimes two or three sets are needed to meet the requirements of supporting a larger transmission ratio. Due to the increase in the number of planetary gears, the length of the second or third high torque planetary gearbox will be increased and the efficiency will be decreased.

Return clearance: when the output end is fixed and the input end is rotated clockwise and counterclockwise to produce rated torque +-2% at the input end, there is a tiny angular displacement at the input end of the high torque planetary gearbox.

Planetary cycloid gear high torque planetary gearbox: the whole transmission device can be divided into three parts: the input part, the reduction part, the output part.Dislocation on the input shaft is equipped with a 180 ° of the double eccentric sleeve, turn on the eccentric sleeve is equipped with two called arm of roller bearing, the formation of H, two cycloid gear center hole is the eccentric sleeve on the turning arm bearing raceway, and by a group of cycloid gear and pin gear mesh circular permutation needle, to form tooth difference, for the internal meshing gear high torque planetary gearbox is institutions (in order to reduce friction, in small ratio of high torque planetary gearbox, the needle with needle teeth on the gear set).When the input shaft is rotated around with an eccentric sleeve, the motion of the cycloid wheel becomes a plane motion with both revolution and rotation due to the characteristics of the tooth profile curve on the cycloid wheel and the limitation of the needle tooth on the needle gear

1) reduce the speed and increase the output torque at the same time. The torque output ratio is the ratio of the motor output to deceleration, but it should not exceed the rated torque of the high torque planetary gearbox.

2) lowering the speed also reduces the inertia of the load, and the reduction of inertia is the square of deceleration ratio.You can look at the fact that a typical motor has an inertia value.

General high torque planetary gearbox has a helical gear high torque planetary gearbox, precision high torque planetary gearbox, servo high torque planetary gearbox, rectangular high torque planetary gearbox, high torque planetary gearbox, helical gear high torque planetary gearbox, strength type high torque planetary gearbox, precise high torque planetary gearbox, cycloid pin wheel high torque planetary gearbox, the worm gear and worm high torque planetary gearbox, planetary friction type mechanical CVT machine, and so on.

Generally there are three: according to the series points reduction gear (usually less than 10:1), double reduction (is generally greater than 10:1 and less than or equal to 200:1), slow (some brands were the third level, the largest reduction ratio do 100:1, the general principle is divided into more than 100:1), but the thunder weed can be done in machine of decelerate of planet of grade 5, reduction ratio do 4592:1;
