Abstract

The invention discloses a machining process of a roller carrier shaft of a belt conveyer, and relates to the field of mechanical manufacturing of conveyers. The machining process comprises the following steps: (1) feeding a blank; (2) milling the end face and punching a center hole; (3) roughly and finely turning the excircle and chamfering; (4) milling a shaft and flattening a groove; (5) grinding the excircle; and (6) relieving stress to anneal. According to the machining process of the roller carrier shaft, the manufacturing precision and strength of the roller carrier shaft are improved through controlling the parameters of the machining procedures of the roller carrier shaft. Moreover, stress relief annealing is finally used in the procedures of the roller carrier shaft to relive the stress in the roller carrier shaft machining procedure. A procedure centralizing principle is used, so that the target can be realized and the cost can be reduced at the same time.

Description

[0001] technical field [0002] The invention relates to the field of conveying machinery manufacturing, in particular to a processing technology for a belt conveyor roller shaft. Background technique [0003] The idler roller is one of the main parts of the belt conveyor. The function of the idler roller is to support the conveyor belt, reduce the running resistance, and make the sag of the conveyor belt not exceed a certain limit to ensure the smooth operation of the conveyor belt. The idler roller accounts for about The weight of the whole machine is 30%~40%. Because of the large number, the quality of the idler roller directly affects the normal operation and operating costs of the conveyor. The idler roller is known as the heart of the conveyor. [0004] One of the most critical parts in the idler is the idler shaft. Because the idler needs to rotate continuously, the manufacturing process of the idler shaft has a great impact on the reliability of the idler. At presen...
