Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a hydraulic device for installing bearings. Background Technology

[0002] Bearings are one of the core components of electric motors, and their installation quality directly affects the test results and service life of the motor. Common bearing installation methods are divided into cold mounting and hot mounting. Cold mounting usually uses a suitable jig to support the inner ring of the bearing, and the operator uses a copper hammer to drive the bearing into the bearing race. This method is simple to operate, but due to uneven force on the bearing, it may cause scratches on the bearing roller.

[0003] In the prior art, patent (CN217890845U) proposes a bearing installation device, including a shaft, which includes a bearing diameter and a shaft extension. A reference hole is provided at the center of the end of the shaft, and the reference hole is screwed to a support stud. A bushing is fitted on the outer side of the shaft extension, with one end of the bushing abutting against the shaft shoulder and the other end abutting against the support stud. A hydraulic nut is fitted on the outer side of the support stud. A bearing is fitted on the outer side of the bushing, and a bearing pressure jack is provided between the bearing and the hydraulic nut. One side of the bearing pressure jack abuts against the hydraulic nut, and the other side abuts against the side of the bearing. The inner diameter of the bearing pressure jack is larger than the maximum outer diameter of the bushing, and the outer diameter of the bushing gradually increases from right to left. This device uses a hydraulic nut to push the bearing, which is a cold installation process and does not require heating the bearing. At the same time, the hydraulic nut pushing the bearing also solves the problem of uneven force when cold-driving the bearing.

[0004] However, in the aforementioned existing technologies, the installation and disassembly of the shaft are relatively inconvenient, and the subsequent replacement of the bearing is not convenient after it is installed stably, which takes a lot of time. Summary of the Invention

[0005] The purpose of this utility model is to provide a hydraulic device for installing bearings, which solves the problems of inconvenient installation and disassembly of shafts in the prior art, and the inconvenience of subsequent replacement after the bearing is installed stably, which consumes a lot of time.

[0006] To achieve the above objectives, this utility model provides a hydraulic device for bearing installation and processing, including a hydraulic base and a processing mechanism. The processing mechanism includes a hydraulic cylinder, a hydraulic rod, a pressure plate, a placement component, a locking component, and two anti-detachment components. The two anti-detachment components are fixedly connected to the hydraulic base and are located on both sides of the hydraulic base. The locking component is fixedly connected to the hydraulic base and is located on the front side of the hydraulic base. The placement component is slidably connected to the hydraulic base and is located on the inner side of the hydraulic base. The pressure plate is fixedly connected to the hydraulic rod and is located at the lower end of the hydraulic rod. The upper end of the hydraulic rod is fixedly connected to the output end of the hydraulic cylinder. The hydraulic cylinder is fixedly connected to the hydraulic base and is located above the hydraulic base.

[0007] The placement assembly includes a placement seat, a limiting plate, and a placement ring. The placement ring is fixedly connected to the placement seat and is located above the placement seat. The limiting plate is fixedly connected to the placement seat and is located on one side of the placement seat. The placement seat is slidably connected to the hydraulic seat and is located inside the hydraulic seat.

[0008] The locking assembly includes a mounting frame, a locking frame, and a locking plate. The locking plate is rotatably connected to the mounting frame and is located inside the mounting frame. The locking frame is fixedly connected to the placement seat and is located on one side of the placement seat. The mounting frame is fixedly connected to the hydraulic seat and is located on the front side of the hydraulic seat.

[0009] Each of the anti-detachment components includes an electric telescopic rod and an anti-detachment sleeve. The anti-detachment sleeve is fixedly connected to the electric telescopic rod and is located at one end of the electric telescopic rod. The electric telescopic rod is fixedly connected to the hydraulic seat and is located on one side of the hydraulic seat.

[0010] The hydraulic base includes a gantry frame and a base. The base is fixedly connected to the gantry frame and located below the gantry frame. The gantry frame is fixedly connected to the hydraulic cylinder and located below the hydraulic cylinder.

[0011] This utility model discloses a hydraulic device for installing bearings. The placement seat within the placement assembly can slide freely within the hydraulic seat. With the limiting effect of the anti-detachment component on the placement seat, the placement seat can move back and forth between the shaft and the bearing being processed. This facilitates the transfer of the fully processed bearing by the operator. This design solves the problems of inconvenient shaft installation and disassembly, and the difficulty in subsequent replacement of bearings after stable installation, which consumes a lot of time, without affecting the hydraulic processing of the bearing.

The 12 is fixedly connected to the hydraulic base 101, the anti-detachment sleeve 116 is fixedly connected to the electric telescopic rod 115, the electric telescopic rod 115 is fixedly connected to the hydraulic base 101, the base 118 is fixedly connected to the gantry frame 117, and the gantry frame 117 is fixedly connected to the hydraulic cylinder 103. The placement seat 109 in the placement component 106 can slide freely in the hydraulic base 101. With the limiting effect of the anti-detachment component 108 on the placement seat 109, the placement seat 109 can move back and forth to process the shaft and bearing, making it convenient for workers to transfer the fully processed bearing. This design solves the problems of inconvenient shaft installation and disassembly, and the inconvenience of subsequent replacement after the bearing is installed stably, which consumes a lot of time, without affecting the hydraulic processing of the bearing.

[0023] The two anti-detachment components 108 are located on both sides of the hydraulic base 101, the locking component 107 is located on the front side of the hydraulic base 101, the placement component 106 is located on the inner side of the hydraulic base 101, the pressure plate 105 is located at the lower end of the hydraulic rod 104, and the hydraulic cylinder 103 is located above the hydraulic base 101.
