Description

Technical Field

[0001] The utility model relates to the technical field of planetary reducers, in particular to a planetary wheel mounting structure of a reducer. Background Art

[0002] The planetary reducer is composed of an inner gear ring, a gearbox housing, a sun gear, etc. The inner gear ring is tightly combined with the gearbox housing, and the sun gear is located at the center of the ring gear and is driven by external power. Between the two, there is a group of three planetary gears equally combined on the planet carrier to form a planetary gear set. This group of planetary gears relies on the output shaft, inner gear ring and sun gear for support. When the input power drives the sun gear, it can drive the planetary gear to rotate and revolve along the center following the trajectory of the inner gear ring, thereby driving the output shaft to output power. It has the characteristics of small size, light weight, high load-bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, and safe performance. It can be used as a supporting component in industrial sectors such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemicals, and construction machinery, and has a wide range of application scenarios.

[0003] During the use of the planetary gears of the existing planetary reducer, the planetary gears, the ring gear and the sun gear rotate continuously and rapidly, and the meshing between them will generate a lot of heat, which will cause the reducer temperature to be too high, affecting the operation of the reducer. In addition, lubricating oil is needed to reduce wear and extend the service life. However, adding lubricating oil requires disassembling the reducer casing, which is extremely cumbersome and has a certain adverse effect on people's use process. In order to solve the shortcomings of the existing technology, we propose a planetary gear installation structure for the reducer. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a planetary gear installation structure of a reducer includes a reducer 1, an external drive motor is inserted into the interior of the reducer 1 through the through hole of the end cover 14, and connected to the input shaft 16, and then the reducer is installed on the drive motor through the fixed installation hole 15. During normal use, the external drive motor rotates, and the internal sun gear 18 drives the input shaft 16 to rotate through the rotation of the drive motor, thereby driving the sun gear 18 to rotate, thereby driving the multiple groups of planetary gears 19 arranged outside the sun gear 18 to rotate at the same time, thereby driving the planetary carrier 20 to rotate, thereby driving the pin shaft 11 arranged on the left side of the planetary carrier 20 to rotate, thereby driving the output shaft 8 to rotate, and the number of teeth between the sun gear 18 and the planetary gear 19 is different, so the rotation speed of the transmission shaft 22 and the output shaft 8 is different, thereby forming a reduction in speed.

[0023] Embodiment 2, as Figure 1-4As shown, a planetary gear mounting structure of a reducer is shown, and a cooling fan 9 will continuously dissipate heat for the inner side of the reducer 1 through the through holes arranged on the side of the reducer 1. When the lubricating oil is insufficient, the lubricating oil can be added to the lubricating oil pipe 4 through the input port 5 arranged at the upper end of the lubricating oil pipe. The lubricating oil falls along the lubricating oil pipe 4, falls on the lubricating oil adding port 12 through the through hole of the auxiliary device 2, and then passes through the through hole 13 into the interior of the reducer, and just drips on the ring gear 17, and then flows to stay between the planetary gear 19 and the sun gear 18, so as to complete the lubrication of the planetary gear 19 of the reducer and extend the service life of the reducer.

[0024] How it works

[0025] It should be noted that the utility model is a planetary gear installation structure for a reducer. When in use, the external drive motor is inserted into the reducer 1 through the through hole of the end cover 14 and connected to the input shaft 16. Then the reducer is installed on the drive motor through the fixed installation hole 15. During normal use, the external drive motor rotates, and the internal sun gear 18 drives the input shaft 16 to rotate through the rotation of the drive motor, thereby driving the sun gear 18 to rotate, thereby driving the multiple sets of planetary gears 19 arranged outside the sun gear 18 to rotate at the same time, thereby driving the planet carrier 20 to rotate, thereby driving the pin shaft 11 arranged on the left side of the planet carrier 20 to rotate, thereby driving the output shaft 8 to rotate, and through the sun gear 18 The number of teeth between the planetary gear 19 is different, so the rotation speed of the transmission shaft 22 and the output shaft 8 is different, thus forming a deceleration. During operation, the cooling fan 9 will continuously dissipate the heat for the inner side of the reducer 1 through the through hole arranged on the side of the reducer 1. When the lubricating oil is insufficient, the lubricating oil can be added to the lubricating oil pipe 4 through the input port 5 arranged at the upper end of the lubricating oil pipe. The lubricating oil falls along the lubricating oil pipe 4, falls on the lubricating oil adding port 12 through the through hole of the auxiliary device 2, and then passes through the through hole 13 into the interior of the reducer, and just drips on the ring gear 17, and then flows to stay between the planetary gear 19 and the sun gear 18, so as to complete the lubrication of the planetary gear 19 of the reducer and extend the service life of the reducer.
