Abstract
The utility model discloses a kind of device being exclusively used in adjustment belt train rate of tension, its structure is, the middle part of base is provided with bar-shaped trough, is provided with displacement stud in bar-shaped trough, belt pulley is installed on displacement stud and fixes with locking nut, in the tapped hole of the screw-in displacement stud of adjustment bolt.The below of displacement stud is provided with locating shoulder, and locating shoulder center is provided with tapped hole, and the thread section of adjustment bolt screws in the tapped hole of locating shoulder.Utilize the displacement stud on base and adjustment bolt to work in coordination, make this belt pulley produce displacement, regulate the tensioning degree of belt thus.The shape of this device pedestal, bolt fixed mode, position and height, can design according to the concrete condition of external engine spatial placement.To in belt train, arbitrary follower that most convenient regulates is fixed in this device, just can regulates the elasticity of drivign belt.This device is convenient to the installation on a production line of motor front-end wheel system annex and adjustment especially.
Description
Technical field
The utility model belongs to engine component, is specifically related to a kind of device adjusting engine belt pulley position.
Background technique
Along with the raising that people require automobile function and travelling comfort, the annex of motor is also being on the increase, and make external engine volume constantly increase like this, but the space of engine assembly car load is but very limited.Therefore how the engine accessory power rating of numerous complicated is carried out reasonable compact assembling, become the common issue that numerous engine production producer faces.In the outside train transmission system of motor, be substantially all rely on drivign belt multiple train to be twined to be connected together, provide power by one of them driving wheel, and drive other to rotate thus.Wherein modal is exactly by crank pulley as driving wheel, sends power to water pump (wheel), air compressor (wheel), generator (wheel) etc. by drivign belt.No matter be that new car dispatches from the factory, or all will regulate the rate of tension of drivign belt along with the lengthening of automobile service time, the method for adjustment is substantially all manage to change angle or the position of certain belt pulley.But as previously mentioned, because engine accessory power rating packaging density is excessive, make to increase pulley position regulating device difficulty comparatively large, controlling device cannot arrange on the engine by namely narrow space.
Accordingly, the utility model proposes a kind of very easy belt tightening controlling device, this device and belt pulley are fitted together, and do not take external engine space in addition, and can conveniently adjusting belt tension degree.
Summary of the invention
The purpose of this utility model is to provide a kind of device being exclusively used in adjustment belt train rate of tension, is applicable to eurypalynous belt tightening and regulates.
For realizing this object structure of the present utility model be: the middle part of base is provided with bar-shaped trough, is provided with displacement stud in bar-shaped trough, and belt pulley is installed on displacement stud and fixes with locking nut, in the tapped hole of the screw-in displacement stud of adjustment bolt.The below of displacement stud is provided with locating shoulder, and locating shoulder center is provided with tapped hole, and the thread section of adjustment bolt screws in the tapped hole of locating shoulder.
Principle of the present utility model is, controlled belt pulley can be any one follower in belt train, utilizes the displacement stud on base and adjustment bolt to work in coordination, makes this belt pulley produce displacement, regulate the tensioning degree of belt thus.
Feature of the present utility model and beneficial effect be, the shape of this device pedestal, bolt fixed mode, position and height, can design according to the concrete condition of external engine spatial placement.To in belt train, arbitrary follower that most convenient regulates is fixed in this device, just can regulate the elasticity of drivign belt.Be convenient to the installation on a production line of motor front-end wheel system annex and adjustment especially.

Embodiment
Structure of the present utility model to be further described by specific embodiment below in conjunction with accompanying drawing.
Be exclusively used in the device of adjustment belt train rate of tension, be made up of base, displacement stud, belt pulley, locking nut, adjustment bolt etc.Its concrete structure is: the middle part of base 1 is provided with bar-shaped trough, is provided with displacement stud 2 in bar-shaped trough, and belt pulley 3 is installed on displacement stud and also fixes with locking nut 4, in the tapped hole of the screw-in displacement stud of adjustment bolt 5.
The below of displacement stud is provided with locating shoulder 2-1, and locating shoulder center is provided with tapped hole, and the thread section of adjustment bolt screws in the tapped hole of locating shoulder.Base side is provided with circular hole, and in the center of circle of circular hole and bar-shaped trough, center line is same straight line, and Circularhole diameter is greater than adjustment bolt external diameter 0.5mm, and base stationary plane 1-1 is provided with three bolts hole.
As embodiment, base bar shaped slot length is 48mm; Groove width is 11mm.The width of locating shoulder is 10.5mm, is less than the width of bar-shaped trough, can not rotate in insertion groove, can only prolong groove direction and move.Displacement stud top 2-2 width is 18mm, ensures to move in base; Position, the aperture 6mm of locating shoulder bolt hole, adjustment bolt screws in this tapped hole.
Rotating adjustment bolt makes displacement stud move along the bar-shaped trough of base, change the position of belt pulley, when displacement stud moves to a certain position, the rate of tension of drivign belt just in time meets the requirements, be exactly now the optimum position of this belt pulley, then with locking nut, pulley position fixed.
