Description

Technical Field

[0001] The present application relates to the technical field of gear transmission, and in particular to an outer gear ring. Background Art

[0002] The outer ring gear is a mechanical part that is usually used in transmission systems to transmit torque and motion. It consists of a series of equally spaced external gears that can have different numbers of teeth. The outer ring gear is used in conjunction with the inner ring gear (internal gear) to achieve transmission through the meshing between the gears. It is commonly used in equipment such as gear reducers and planetary gear transmissions to achieve speed reduction and torque increase between the input shaft and the output shaft. The outer ring gear has a wide range of applications in industrial production and mechanical fields, such as automotive transmissions, aircraft engines, construction machinery, etc. Its design and manufacturing need to consider factors such as gear strength, precision, lubrication and noise to ensure its normal operation and long life.

[0003] When the outer gear ring is subjected to heavy loads or frequent cyclic loads, fatigue cracks may occur, resulting in part failure. After the part fails, it will be replaced with a new one, resulting in high maintenance costs. Summary of the invention

[0004] In order to reduce maintenance costs, the present application provides an outer gear ring, which adopts the following technical solution:

[0005] An outer gear ring, comprising:

[0006] Ring gear body;

[0007] A gear ring, the gear ring body being sleeved on the gear ring;

[0008] A locking component is used to lock the gear ring body and the gear ring.

[0009] By adopting the above technical solution, since the gear ring body is sleeved on the gear ring, the gear ring and the gear ring body are locked by the locking component. Therefore, when the gear ring is damaged, only the gear ring needs to be replaced, or when the gear ring body is damaged, only the gear ring body needs to be replaced, and there is no need to replace the entire outer gear ring, thereby reducing maintenance costs.

[0010] Optionally, the locking component includes:

[0011] A locking plate, mounted on the end surface of the ring gear body;

[0012] A locking bolt is threadedly connected to the locking plate and the gear ring.

[0013] By adopting the above technical solution, when locking the gear ring body and the gear ring, the locking plate is brought into contact with the end faces of the gear ring body and the gear ring, and then the locking plate is locked by the locking bolt, thereby achieving the installation of the gear ring body and the gear ring.

[0014] Optionally, a guide connection block is fixedly connected to the outer wall of the gear ring; a connection groove is opened on the inner wall of the gear ring body, and the guide connection block is slidingly connected to the inner wall of the gear ring body through the connection groove.

[0015] By adopting the above technical solution, the guide connection block can enhance the stability of the connection between the gear ring body and the gear ring.

[0016] Optionally, the ring gear body comprises:

[0017] A gear ring connecting ring, sleeved on the gear ring;

[0018] The sector-shaped gear ring segment is provided with multiple segments, and the multiple segments of the sector-shaped gear ring segments are all installed on the gear ring connecting ring;

[0019] A connecting component, adjacent sector gear ring segments are connected by the connecting component.

[0020] By adopting the above technical solution, when the gear ring body is damaged, a damaged sector-shaped gear ring segment can be replaced separately, thereby further reducing the maintenance cost.

[0021] Optionally, the connecting component includes:

[0022] A rotating piece, rotatably connected to one end of the end surface of the sector gear ring;

[0023] A fixed column, fixedly connected to the other end of the end surface of the sector gear ring, and the rotating sheet can be clamped on the fixed column of the adjacent sector gear ring;

[0024] A connecting nut is threadably connected to the fixing column and is used to compress the rotating sheet.

[0025] Optionally, a positioning block is fixedly connected to the gear ring connecting ring, and the sector-shaped gear ring segment is provided with a positioning groove, and the positioning block can be snapped into the positioning groove.

[0026] By adopting the above technical solution, the assembly of the sector-shaped gear ring segment can be positioned.

[0027] In summary, the present application has at least the following beneficial effects:

[0028] 1. The purpose of setting the gear ring body, gear ring and locking component is that since the gear ring body is sleeved on the gear ring, the gear ring and the gear ring body are locked by the locking component. Therefore, after the gear ring is damaged, only the gear ring needs to be replaced, or after the gear ring body is damaged, only the gear ring body needs to be replaced, and there is no need to replace the entire outer gear ring, thereby reducing the maintenance cost.

[0029] 2. The purpose of setting the guide connection block is that the guide connection block can enhance the stability of the connection between the gear ring body and the gear ring.

[0030] 3. The purpose of providing the gear ring connecting ring, the sector gear ring segments and the connecting parts is that when the gear ring body is damaged, a damaged sector gear ring segment can be replaced separately, thereby further reducing the maintenance cost.

[0031] 4. The purpose of setting the positioning block is to position the assembly of the sector gear ring segment. BRIEF DESCRIPTION OF THE DRAWINGS
