Problems solved by technology

However, when the number of loads is small, there is no need to use pulleys with so many pulley grooves, so it will cause waste of materials, and increase the cost and processing time, and the protruding part of the pulley is too long, which not only affects the overall appearance of the engine, And it is not conducive to the normal operation of the engine

Embodiment 1

[0023] Such as Figure 1 to Figure 2 As shown, the superimposed pulley of this embodiment includes: a main pulley 1 and a plurality of auxiliary pulleys 2, and the plurality of auxiliary pulleys 2 are superimposed and arranged on the upper end surface of the main pulley 1 ( figure 2 It is shown that six auxiliary pulleys are superimposed), and the upper end surface of the outer ring of the main pulley 1 is provided with a plurality of bolt holes along the circumferential direction. The outer ring of each auxiliary pulley 2 is processed with a convex portion 21, the outer ring of each auxiliary pulley 2 is provided with a plurality of through holes in the circumferential direction, and the plurality of auxiliary pulleys 2 are fixedly connected with the main pulley 1 by bolts 3. Among them, the main pulley 1 and each auxiliary pulley 2 are provided with two positioning holes for installing positioning pins 4, so that the main pulley 1 and the auxiliary pulley 2 can be positioned ...

Abstract

The invention discloses an overlaid-type belt pulley. The overlaid-type belt pulley comprises a main belt pulley and one or more auxiliary belt pulleys; a plurality of main belt pulley grooves are machined in an outer ring of the main belt pulley, and a plurality of bolt holes are formed in the circumferential direction of the upper end face of the outer ring of the main belt pulley; a protrudingpart is machined on an outer ring of each auxiliary belt pulley, a plurality of through holes are formed in the circumferential direction of the outer ring of each auxiliary belt pulley, and the one or more auxiliary belt pulleys and the main belt pulley are fixedly connected through bolts; and the main belt pulley and all the auxiliary belt pulleys are each provided with two positioning holes formounting positioning pins, and thus the main belt pulley and the auxiliary belt pulleys can be positioned through the positioning pins. The number of the belt pulley grooves can be increased by increasing the number of the auxiliary belt pulleys, and thus can be reasonably selected to meet the requirements of loads of different numbers, thus material waste is avoided, the machining efficiency isimproved, and the machining cost is lowered.

Description

Technical field [0001] The present invention relates to a belt pulley, in particular to a superimposed belt pulley. Background technique [0002] At present, engines (including diesel engines, gasoline engines and other types of internal combustion engines) are driven by front-end pulleys to drive related loads (such as generators, sea water pumps, steering gears, etc.). According to different user requirements, the engine needs to drive a different number of loads. As a result, different engines need to match pulleys with different pulley groove numbers. [0003] The traditional pulley is an integrated structure, and more pulley grooves are processed in the convex part of the pulley, so that the pulley with a larger number of pulley grooves can meet the different needs of more users. However, when the load is small, there is no need to use so many pulleys with pulley grooves, which will cause waste of materials, increase cost and processing time, and the protruding part of the pu...
