Problems solved by technology
[0008] In order to solve the problems of insufficient structural strength caused by the connection between the two discs of the existing planetary gear device with only pivots and C-shaped buckles, the gear oil is difficult to flow into each pivot for cooling and lubrication, and the C-shaped buckles are easy to fall off, etc., The main purpose of the present invention is to provide a planetary gear device and its planetary gear set. The planetary gear set uses a fixed bracket and a fixed plate as the main support structure to make the overall structure more stable and cooperate with the oil guide groove for cooling. lubricating

The invention relates to a planetary gear system and a planetary gear set thereof. The planetary gear system mainly comprises a planetary arm tray stand, an inner ring gear and the planetary gear set, the planetary arm tray stand is connected with the inner ring gear, and the planetary gear set can be rotatably connected on the inner circumference of the inner ring gear in a meshed manner and fixedly connected to the planetary arm tray stand. The planetary gear set comprises a fixing bracket, a sun gear, at least one planetary gear and a fixed disk, wherein the sun gear is fixed to the fixing bracket, the planetary gears are fixed to the fixing bracket and annularly arranged on the outer circumference of the sun gear, and the fixed disk covers the fixing bracket and is fixed to the fixing bracket. The sun gear and the planetary gears can be stably combined by the aid of the fixing bracket and the fixed disk, so that the planetary gear set cannot easily generate torsional deformation in actuation, and the service life of the planetary gear set cannot be affected.
Description
technical field [0001] The invention relates to a reduction mechanism component, in particular to a planetary gear device and a planetary gear set thereof. Background technique [0002] The general reducer is to connect the motor and reduce the motor speed to achieve a larger torque. Inside the reducer, various gear mechanisms are used to reduce the speed, such as Figure 7 and Figure 8 As shown, it is an existing planetary gear device 60 used for a reducer, which includes a planetary arm tray frame 61, an inner ring gear 62 and a planetary gear set 63, wherein the planetary arm tray frame 61 and the inner ring The gears 62 are connected, and the inner circumference of the inner ring gear 62 has a ring-shaped inner tooth portion 621. The planetary gear set 63 is rotatably arranged on the inner tooth portion 621, and is connected and fixed on the planetary arm tray frame. 61, the planetary gear set 63 includes a first disc 631, a second disc 632 for fixing, and a rotatably ...
