Abstract
The utility model discloses a motorcycle chain stretcher, which is characterized in that the fixed arm 8 is directly or through the fixing device 9 fixed on the rear wheel spindle stick 1 or the vehicle frame 2. The rocking arm 4 is connected with the fixing arm 8 through a spin axis 5. The torsion spring 6 takes the spin axis 5 as the mandrel, one end is fixed on the fixing arm 8 and the other end is fixed on the rocking arm 4. Each end of the rocking arm 4 is provided with a guide pulley 3 and a guide pulley 7 connected with the chain 1. The utility model guarantees the driving chain in the condition of appropriate tension all the time so as to reduce the chain vibration, decrease the chain wear and prolong the machinery durability. Meanwhile, the utility model reduces power loss and economizes fuel indirectly and need not be adjusted in use.
Description
Affiliated technical field:
The utility model belongs to transmission field, refers in particular to a kind of adjusting that in use do not need, and guarantees that chain is in the chain tensioning device of suitable tensioning state constantly.
Background technology:
The motor bike engine installation is by chain gear, drives trailing wheel and rotates to overtake.In vehicle ' after a period of time, chain is because wearing and tearing and elongated, makes that vibrations, climbing tooth appear in chain, phenomenon such as come off, and also causes power waste simultaneously, and the waste fuel oil must solve these problems by adjusting the chain tension degree.And the method for adjusting the chain tension degree now is by adjusting centre of sprocket apart from finishing.This method wastes time and energy, technical sophistication, adjusts improperly to cause physical damage easily, even leads to a disaster.
Summary of the invention:
The purpose of this utility model is to provide a kind of needn't the adjustment just can guarantee that driving chain is in the chain tensioning device of suitable tensioning state constantly, chain vibration is reduced, reduce chain wear, increase mechanical service life, the generation of phenomenon such as stop the chain climbing tooth, come off, reduce power waste simultaneously, the indirect saving fuel oil.
The purpose of this utility model is achieved in that fixed arm directly or by anchor fitting is fixed on hind axle rod or the vehicle frame; rocking arm is connected with fixed arm by rotating shaft; torsion spring is mandrel with the rotating shaft; an end is fixed on the fixed arm; the other end is fixed on the rocking arm; the rocking arm two ends are respectively installed a guide wheel and contacted with chain, makes chain be " S through two guide wheels the time " type.When the chain tension degree changed, torsion spring acted on rocking arm and drives the guide wheel be installed in the rocking arm two ends and act on chain, forces chain to be in suitable tensioning state.
Feature of the present utility model is: guide wheel adopts the flute profile guide wheel.
Feature of the present utility model is: the chain to duplex structure carries out tensioning, and two guide wheels can be installed on guide wheel shaft side by side.
Advantage of the present utility model is: can guarantee that driving chain is in suitable tensioning state constantly, two guide wheel designs can better increase the chain degree of stability, make chain vibration littler, reduce chain wear, increase mechanical service life, phenomenon such as stop the chain climbing tooth, come off reduces power waste, the indirect saving fuel oil simultaneously.
Description of drawings:
Accompanying drawing is the sketch of the utility model structure and embodiment.
Fig. 1: for the utility model A to structure diagram.
Fig. 2: be the utility model construction profile sketch.
Fig. 3: for the utility model is specifically implemented sketch.
Among the figure:
1---chain 5---rotating shaft 8---fixed arm
2---vehicle frame 6---torsion spring 9---anchor fittings
3---guide wheel 7---guide wheel 10---hind axle rods
4---rocking arm
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described further: fixed arm 8 directly or by anchor fitting 9 is fixed on hind axle rod 10 or the vehicle frame 2; Rocker arm 4 is connected with fixed arm 8 by rotating shaft 5; torsion spring 6 is a mandrel with rotating shaft 5; end is fixed on the fixed arm 8; other end is fixed on the Rocker arm 4; a guide wheel 3 respectively is installed at the Rocker arm 4 two ends and guide wheel 7 contacts with chain 1, make chain 1 through two guide wheels 3 and be " S at 7 o'clock " type.When chain 1 degree of tension changed, torsion spring 6 acted on Rocker arm 4 and drives the guide wheel 3 and 7 be installed in the rocking arm two ends and act on chain 1, forces chain 1 to be in suitable tensioning state.
Feature of the present utility model is: guide wheel adopts the flute profile guide wheel.
Feature of the present utility model is: the chain to duplex structure carries out tensioning, and two guide wheels can be installed on guide wheel shaft side by side.
