Description

Technical Field

[0001] This utility model relates to a motor gear fixing structure for a silage harvester. Background Technology

[0002] Currently, the methods for mounting gears in silage harvester motors used in China include: direct mounting, flange mounting, keyway mounting, and adapter sleeve mounting. Direct mounting involves fitting the gear onto the motor shaft and then securing it with pins or fixing screws. This structure is simple but not suitable for high-power motors. Flange connections require flanges on both the motor and the gear, which are then secured with mounting bolts. While this meets the requirements, the structure is relatively complex and costly. Adapter sleeves secure the gear using clamping force, and their structure is also relatively complex. Keyway connections are relatively simple in structure, low in cost, and offer good stability, but axial slippage occurs during operation. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a motor gear fixing structure for silage harvesters.

[0004] A motor gear fixing structure for a silage harvester includes a hydraulic motor, a gear, and a self-locking mechanism. The gear is connected to the outside of the drive shaft of the hydraulic motor by a key. The inner sidewall of the gear is provided with an annular groove. The self-locking mechanism includes a retaining ring, which is engaged in the annular groove, and its bottom surface is fixedly connected to the end face of the drive shaft.

[0005] Furthermore, a baffle is provided between the retaining ring and the end face of the drive shaft, and a step is provided on the inner side wall of the gear. The baffle is placed above the step, and the baffle, retaining ring, and drive shaft end face are fixedly connected.

[0006] Furthermore, the baffle, retaining ring, and drive shaft are connected by bolts, which pass through the end faces of the retaining ring, baffle, and drive shaft in sequence.

[0007] Furthermore, the hydraulic motor is fixedly connected to the mounting base by at least four bolts.

[0008] Furthermore, the key is made of steel.

[0009] Furthermore, the gear is made of steel.

[0010] Beneficial effects: Compared with the prior art, this utility model adds a retaining spring and a baffle inside the gear and fixes the gear with bolts, so that the gear will not slide axially or shift under the action of force when the hydraulic motor is running, thus better engaging with the meshing gear. At the same time, the key connection between the gear and the hydraulic motor is more secure, the structure is relatively simple and low in cost, and it is not easy to slip.
