Description

Technical Field

[0001] The utility model relates to the technical field of equipment for processing needle roller bearings without inner rings, in particular to a cleaning device for processing needle roller bearings without inner rings which is easy to access. Background Art

[0002] Needle roller bearings without inner rings are a special type of bearing, primarily consisting of an outer ring, a needle roller assembly, and a cage. Due to their lack of an inner ring, they are mounted directly on the shaft and are typically used in combination with needle rollers and inner rings of the same model. This design allows the shaft journal to serve directly as the rolling surface, placing high demands on the shaft's raceway surface. This design can accommodate bearing structures with limited radial mounting dimensions, thereby improving the lifespan and operating accuracy of the entire equipment.

[0003] At present, the existing cleaning devices need to be positioned when cleaning bearings, and the positioning structures of the existing cleaning devices mostly use bolts to clamp and position the outside of the bearings. Although this method can effectively fix the bearings, the process of manually fixing the bearings is relatively cumbersome, which makes it inconvenient for personnel to store and locate the bearings. In addition, long-term use of the bolts may be affected by external factors and cause thread slippage, which undoubtedly increases the operational burden and reduces the practicality of the device. Therefore, we propose a cleaning device for processing needle roller bearings without inner rings that is easy to store and access to solve the above problems. Utility Model Content

Specifically, by starting the clamping component, the two clamping seats 10 are moved to clamp the outside of the bearing, and the positioning component is started to drive the extrusion plate 13 downward to position the top of the bearing, which is suitable for bearings of different sizes to a certain extent. At the same time, it is convenient for personnel to place or remove bearings. Start the built-in water pump in the water tank 2 and use multiple nozzles 9 to flush the bearing through the transmission pipe 4 and the water storage pipe 3, which reduces the operating burden of personnel and improves the practicality of the device.

[0025] Furthermore, the clamping assembly includes a motor 5 arranged on one side of the box body 1. The bottom of the motor 5 is fixedly installed on the side wall of the box body 1 through a bracket. The output end of the motor 5 is driven and connected to a bidirectional screw rod 6. The end of the bidirectional screw rod 6 away from the motor 5 is rotatably connected to the inner wall adjacent to the cleaning tank. Specifically, through the setting of the bidirectional screw rod 6, the bidirectional screw rod 6 is driven to rotate by starting the motor 5, and then the two screw sleeves 7 are horizontally displaced closer to each other along the guide rod. The screw sleeve 7 then drives the connecting rod 8 to move the clamping seat 10 and clamp and position the outside of the bearing, thereby achieving a stable positioning of the bearing and adapting to bearings of different sizes to a certain extent, making it convenient for personnel to place and remove, reducing the operating burden, and improving the practicality of the device.

[0026] Furthermore, the clamping assembly also includes two screw sleeves 7 respectively sleeved on the two ends of the outside of the bidirectional screw rod 6, and one side of the outer ring of the two screw sleeves 7 is fixedly connected to the end of the adjacent connecting rod 8 away from the clamping seat 10.
