Description

Technical Field

[0001] The utility model relates to the technical field of fatigue-resistant planetary wheel carrier mechanisms, in particular to a fatigue-resistant planetary wheel carrier mechanism. Background Art

[0002] The planetary gear carrier mechanism is a circular frame that supports the internal meshing transmission gears, which can ensure the stable rotation of the meshing gears.

[0003] For example, a fatigue-resistant planetary gear carrier mechanism with the announcement number "CN220302714U" absorbs and dissipates the heat generated by the rotation friction between the ring gear and the planetary gear through the set annular cavity, an annular heat-conducting ring and the coolant filled between the two, so as to prevent the ring gear from heating up due to long-term friction and affecting its service life, resulting in reduced fatigue resistance. At the same time, through the cooperation of the set air outlet, air inlet, guide pipe, ventilation pipe, wind collecting scoop, fan and filter, cold air is blown into the annular cavity to take away the heat conducted by the annular heat-conducting ring, thereby further enhancing the heat dissipation efficiency, thereby enhancing fatigue resistance and extending the service life of the planetary gear carrier. However, although cooling is achieved in the use of the planetary gear carrier mechanism, the wear between the gears is not reduced, and the ring gear cannot be disassembled. After damage, the planetary gear carrier mechanism needs to be replaced as a whole. In addition, the cooling structure also increases the overall volume and is prone to installation conflicts, resulting in limitations in the use of the planetary gear carrier mechanism and increasing the use cost of the planetary gear carrier mechanism. Utility Model Content

The inner wall of the bracket is connected to the control structure.

[0007] Preferably, the mounting structure includes a bent plate and a screw rod, the rear end face of the bent plate is fixedly connected to the front face of the bracket, the front face of the bent plate is threadedly connected to the screw rod, and the front face of the screw rod is fixedly connected to a handle.

[0008] Preferably, the rear of the outer wall of the screw is threadedly connected to the inner wall of the square plate.

[0010] Preferably, the front surface of the transverse plate is in contact with the rear end surface of the bracket.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-4: In this embodiment, a fatigue-resistant planetary gear frame mechanism includes a bracket 1 and a slide groove 4. The front of the bracket 1 is processed with multiple slide grooves 4. The inner wall of the slide groove 4 is slidably connected with a straight cylinder 5. The straight cylinder 5 is subjected to force to slide in a track through the inner wall of the slide groove 4. The upper and lower sides of the front of the bracket 1 are respectively connected with the mounting structure 2. The front of the bracket 1 is fitted with a gear ring 6. The upper and lower sides of the gear ring 6 are respectively fixed with square plates 7. The inner wall of the bracket 1 is connected with a control structure 3.

[0021] The mounting structure 2 includes a bent plate 201 and a screw 202. The rear end face of the bent plate 201 is fixedly connected to the front face of the bracket 1. The front face of the bent plate 201 is threadedly connected to the screw 202. The screw 202 is subjected to force through the front face of the bent plate 201 and rotates back and forth. The front face of the screw 202 is fixedly connected to a handle 203, which facilitates driving the screw 202 to rotate. The rear outer wall of the screw 202 is threadedly connected to the inner wall of the square plate 7.

[0022] By holding the handle 203 in the mounting structure 2 and rotating it, the handle 203 drives the screw 202 to rotate forward through the bent plate 201, so that the rear of the outer wall of the screw 202 is separated from the inner wall of the square plate 7, and then the gear ring 6 is rotated to drive the square plate 7 to rotate away from the inside of the bent plate 201, and then the gear ring 6 is removed, and then the new gear ring 6 is fitted with the bracket 1, and the gear ring 6 is rotated to insert the square plate 7 into the bent plate 201, and then the handle 203 drives the screw 202 to rotate backward through the bent plate 201, so that the rear of the outer wall of the screw 202 is threadedly connected to the inner wall of the square plate 7, completing the replacement of the gear ring 6, eliminating the use limitations of the planetary gear carrier mechanism, and reducing the use cost of the planetary gear carrier mechanism.

[0023] The control structure 3 includes a circular plate 301 and a transverse plate 302. The outer wall of the circular plate 301 is plugged into the inner wall of the bracket 1. The circular plate 301 can be pulled backward under force to detach from the inner wall of the bracket 1. The left and right sides of the rear end face of the circular plate 301 are respectively fixed to the inner side of the front face of the transverse plate 302. The inner wall of the transverse plate 302 is threadedly connected with a bolt 303. The bolt 303 fixes the transverse plate 302 and the bracket 1. The front face of the transverse plate 302 fits the rear end face of the bracket 1, and the front of the outer wall of the bolt 303 is threadedly connected to the rear end face of the bracket 1.

[0024] Working principle:

[0025] Planetary gear carrier mechanism installation:

[0026] The outer wall of the circular plate 301 is inserted into the inner wall of the bracket 1. At this time, the front of the horizontal plate 302 will fit with the rear of the bracket 1. Then the bolt 303 is threaded through the horizontal plate 302 from back to front and threadedly connected to the rear end face of the circular plate 301 to complete the fixation of the circular plate 301 and the bracket 1. Then the circular opening on the outer wall of the bracket 1 is fit with the connection, and the screw is threaded through the circular opening from right front to rear to fix it. Then the straight cylinder 5 is slid on the inner wall of the slide groove 4 to adjust its position, and then the screw is passed through the straight cylinder 5 and threadedly fixed to the connection. Then the gear and the bearing are installed in the front circular opening of the circular plate 301, so that the gear engages with the inner wall of the gear ring 6 at the same time.

[0027] Replacement of the planetary gear ring:

[0028] Hold the handle 203 and rotate it. The handle 203 drives the screw 202 to rotate forward through the bent plate 201, so that the rear of the outer wall of the screw 202 is separated from the inner wall of the square plate 7. Then the gear ring 6 is rotated to drive the square plate 7 to rotate away from the inside of the bent plate 201. Then the gear ring 6 is removed, and the new gear ring 6 is fitted with the bracket 1. The gear ring 6 is rotated to insert the square plate 7 into the bent plate 201. Then the handle 203 drives the screw 202 to rotate backward through the bent plate 201, so that the rear of the outer wall of the screw 202 is threadedly connected to the inner wall of the square plate 7. The replacement of the gear ring 6 is completed, the problem of overall replacement is solved, and the fatigue resistance of the planetary gear carrier mechanism is ensured.

[0029] Example 2:

[0030] See also Figure 1-4 : In this embodiment, a fatigue-resistant planetary gear carrier mechanism also includes a fin plate 8, and the inner sides of multiple fin plates 8 are fixedly connected to the outer wall of the gear ring 6.

[0031] Working principle:

[0032] When the gears mesh with the inner wall of the gear ring 6 and rotate at high speed to generate heat, the fins 8 can absorb and dissipate the heat through their own copper material, thereby improving the heat dissipation capacity of the gear ring 6.
