Abstract

The invention discloses a tapered roller bearing pressing and assembling device. The tapered roller bearing pressing and assembling device comprises a pressure machine, and a pressing rod, a pressing head and a guiding head which are sequentially connected along a pressure effect line of the pressure machine, wherein the pressing rod is fixedly connected to the pressure machine, a cavity is formed in the pressing head, the guiding head is fixedly connected to the inner part of the cavity through a connecting rod, and under the effect of spring force, the guiding head moves back and forth along the pressure effect line in the cavity; under the feed condition, a tapered roller bearing is assembled outside the guiding head in a sleeving manner and fixed on the guiding head through a ball head plunger, and the end surface of the tapered roller bearing is abutted to the guiding head; under the pressing and assembling condition, the guiding head is embedded into a positioning hole in a shaft to be pressed and assembled, and the pressing head is connected with the tapered roller bearing in a pressing manner on the shaft to be pressed and assembled. Through the adoption of the technical scheme, the working strength of manual pressing and manual assembling of an operator is reduced, and besides the pressing accuracy and the assembling accuracy of the tapered roller bearing are improved.

Description

technical field [0001] The invention relates to the technical field of bearing press-fitting, in particular to a press-fitting device for tapered roller bearings. Background technique [0002] Tapered roller bearings are widely used in the mechanical field. At present, in the assembly of tapered roller bearings, assemblers generally use press-fitting tools and knocking aids for assembly. Pressing tools such as figure 1 As shown, there is a cavity 11' in the pressing tool 1', and a sinking platform 12' is provided at the end in contact with the tapered roller bearing 2'. The end face of the tapered roller bearing 2' is against the sinking platform 12', and passes The percussion aid strikes the bottom end of the press-fitting tool. [0003] In the above installation structure, due to the randomness of manual knocking, the knocking force is difficult to ensure the concentricity of the tapered roller bearing and the shaft to be pressed, resulting in poor assembly accuracy; Re...
