Problems solved by technology

[0002] The assembly of existing crane wheel bearings usually adopts the shrink-fit method. After the oil is heated, the bearings are pressed into the wheels and then transition fit. The operating mechanism on a crane has four wheels, and two bearings need to be installed on each wheel. The disadvantages of the above method of assembly are: first, the assembly speed is slow, and second, the quality is difficult to guarantee, which affects the delivery time and brings economic losses to the enterprise

Abstract

The invention discloses a crane wheel bearing pressing-in device which comprises a machine frame. The machine frame is of a door-shaped framework composed of an upper beam and side beams. A disc capable of bearing a hydraulic device is fixed to the center of the upper beam of the framework through a bolt. A positioning device and a base plate of a moving part are fixed to the foundation face inside the door-shaped framework. The hydraulic device is composed of a hydraulic cylinder, a hydraulic rod and a cylindrical pressing head. The positioning device is formed by a rectangular steel plate. An inverted-V-shaped gap is formed inside the steel plate. The base plate is a solid circular steel plate. A handle is welded to the outer circumferential wall of the steel plate. The rod wall of the hydraulic rod is wrapped by the cylindrical pressing head. A hole for assembling the hydraulic rod is drilled in the center of the cylindrical pressing head, and the hydraulic rod is in interference fit with the cylindrical pressing head. According to the technical scheme, hydraulic pressure is adopted as power to press a bearing into a wheel, a protective device is arranged to protect the bearing against damage, assembly is fast carried out in an effortless mode, the quality is ensured, and therefore production efficiency is improved.

Description

Technical field: [0001] The invention relates to a bearing assembling device, which is especially suitable for pressing and assembling crane wheel bearings. Background technique: [0002] The assembly of existing crane wheel bearings usually adopts the shrink-fit method. After the oil is heated, the bearings are pressed into the wheels and then transition fit. The operating mechanism on a crane has four wheels, and two bearings need to be installed on each wheel. The disadvantages of the above method of assembly are: firstly, the assembly speed is slow, and secondly, the quality is difficult to guarantee, thereby affecting the delivery time and bringing economic losses to the enterprise. Invention content: [0003] The task of the present invention is to propose a crane wheel bearing press-in device with fast assembly speed and guaranteed quality. [0004] The task of the present invention is accomplished in this way, a crane wheel bearing press-in device, which includes ...
