Embodiment Construction

[0015] As shown in attached drawing 1, the outer dimension of the bush is φ560×φ670×220 (mm); the material of the bush is No. 45 steel, quenched and tempered; , the tolerance is -0.01 +0.03 mm; the coaxiality of the inner and outer surfaces of the bushing is not greater than 0.035mm; the roundness error of the inner and outer surfaces is not greater than 0.05mm; the verticality error of the two ends facing the inner and outer surfaces is not greater than 0.04mm; 2 ~ 4mm. After carefully analyzing the technical requirements of the product, the process is arranged according to the technical solution of the present invention, and the effect is good through verification.

Abstract

The present invention belongs to the field of bearing technology, and is process of producing bearing lining for the power end of mechanical diaphragm pump. The production process includes the following steps: coarse turning to form the surfaces, quenching and tempering, dissecting, combining, finish turning the surfaces, coarse grinding the surface, additional tempering, finish grinding the surfaces, separating and treating cuts, measuring deformation and trimming. The present invention solves the problem of installing non-split crankshaft bearing, and is significant economically.

Description

Technical field [0001] The invention belongs to the technical field of bearings and relates to a processing method for a bearing bush at the power end of a mechanical diaphragm pump. Background technique [0002] The half bush is the crankshaft bearing bush at the power end of the mechanical diaphragm pump. According to the needs of the user, due to the limitation of the design space of the main engine, and considering the load and economy, the user does not use split bearings, but uses normal spherical roller bearings. In order to solve the problem of bearing installation, the half bush is made by ourselves when ordering the bearing. However, after testing, the accuracy of the user-made half bushing is far from meeting the design requirements of the main engine. Contents of the invention [0003] The purpose of the present invention is to provide a processing method for the bearing bush at the power end of a mechanical diaphragm pump to solve the problem of processing a...
