Problems solved by technology

It is a better tensioning method to use an automatic tensioner to tension the front wheel train belt, which can ensure the tension of the belt and make the front wheel train run reliably, but some wheel trains have small space, which makes the automatic tensioner unable to At the same time, the price of the automatic tensioner is relatively high, and the cost is relatively high for small displacement engines; the cost of adjusting the pulley of the front-end wheel system components to tension the belt is relatively low, but the adjustment of the belt tension during later maintenance Tightness is more troublesome, and at the same time, when the wrap angle of the pulley at the front end of some wheel trains is small, it cannot play the role of increasing the wrap angle of the pulley

Embodiment Construction

[0011] see figure 1 , the present invention is composed of a mandrel 1, a bearing 2 (due to the existing common structure, it is only schematically expressed in the figure, and the inner and outer rings are not clearly drawn) and a pulley 3, and the inner rings of the mandrel 1 and the bearing 2 are made of The pulley 3 and the outer ring of the bearing 2 are connected together by an interference fit. A bolt connection hole and an adjustment hole are distributed on the mandrel 1, and the bolt connection hole 12 is set eccentrically. The bolt connection hole 12 is a round hole, and the adjustment hole 11 is a hexagonal blind hole.

[0012] When the mandrel 1 is tightened by the bolts passing through the bolt connection hole 12 on the mandrel, the mandrel 1 and the inner ring of the bearing 2 are fixed together, and the outer ring of the bearing 2 rotates together with the pulley 3 under the drive of the belt 7, as figure 2 shown. Wherein the feature of each component is: a h...

Abstract

The invention provides a motor head gear train belt tightener which consists of a mandrel, a belt pulley and a bearing. The mandrel 1 is mounted inside the bearing 2 and in interference fit with an inner ring of the bearing, and the belt pulley 3 is mounted outside of the bearing 2 and in interference fit with an outer ring of the bearing 2. A bolt connecting hole and a regulating hole are arranged on the mandrel 1, and the bolt connecting hole 12 is eccentrically arranged. The motor head gear train belt tightener is low in cost, simple and compact in structure, convenient to mount and adjust belt, small in size and capable of enlarging wrap angle of the belt pulley. Purposes for reducing high cost and solving difficulties in adjustment and maintenance are realized, and the wrap angle of the motor head gear train belt pulley can be enlarged.

Description

technical field [0001] The invention relates to a wheel system at the front end of an automobile engine, in particular to a tensioning device for a belt at the front end of the engine. Background technique [0002] The belt tensioning of the existing front wheel train of the engine generally adopts an automatic tensioner to tension or adjust a certain component pulley in the front wheel train to tension the belt. It is a better tensioning method to use an automatic tensioner to tension the front wheel train belt, which can ensure the tension of the belt and make the front wheel train run reliably, but some wheel trains have small space, which makes the automatic tensioner unable to At the same time, the price of the automatic tensioner is relatively high, and the cost is relatively high for small displacement engines; the cost of adjusting the pulley of the front-end wheel system components to tension the belt is relatively low, but the adjustment of the belt tension during ...
