Abstract
The utility model relates to a tension pulley bracket, which includes a pin hole, wherein symmetrical through holes are arranged in the upper end surface of the tension pulley bracket; a through hole is formed at the lower end part of the tension pulley bracket; the pin hole is also arranged in the upper end surface of the tension pulley bracket between the through holes; a threaded hole is arranged at the center of the tension pulley bracket between the through holes; and a round pin is fixedly mounted in the pin hole. The tension pulley bracket provided by the utility model has the advantages of compact structure and reasonable design, realizes the gear train adjustment within a smaller space and saves space; the structure of an engine is compact; and the mounting difficulty of accessories is reduced.
Description
Technical field
The utility model relates to a kind of Idle wheel support.
Background technique
At present, train arranges that general space is less, generally realizes the tensioning of train through the belt wheel position of adjustment train annex, influences the compactedness of motor.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and saves a kind of Idle wheel support in space.In order to achieve the above object; The technological scheme that the utility model adopts is: comprise pin-and-hole; Be provided with the through hole and the through hole of symmetry in Idle wheel support upper-end surface, have through hole at Idle wheel support lower end part, the Idle wheel support upper-end surface between through hole and the through hole also is provided with pin-and-hole; Be provided with tapped hole at the through hole of symmetry and the Idle wheel carriage center position between the through hole, in pin-and-hole, be fixed with straight pin.The utility model has the advantages that: compact structure, reasonable in design, in less space, realized the adjustment of train, save the space, motor is compact, has reduced the installation difficulty of annex.

Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model straight pin is connected schematic representation with pin-and-hole;
Fig. 3 is the utility model stretching wheel assembly structural representation;
Fig. 4 is that the utility model driving pulley is connected schematic representation with driven pulley, stretching wheel assembly.
Embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Can know by Fig. 1-Fig. 4; The utility model comprises pin-and-hole 4; Be provided with the through hole 2 and through hole 6 of symmetry in Idle wheel support 1 upper-end surface, have through hole 3 at Idle wheel support 1 lower end part, Idle wheel support 1 upper-end surface between through hole 6 and the through hole 3 also is provided with pin-and-hole 4; Be provided with tapped hole 5 at the through hole 2 of symmetry and Idle wheel support 1 center portion between the through hole 6, in pin-and-hole 4, be fixed with straight pin 8.The utility model is connected fixed tensioning wheel support 1 at through hole 2, through hole 3 and the through hole 6 of Idle wheel support 1 with motor through bolt.Straight pin 8 on pin-and-hole 4 and the stretching wheel assembly 7 connects; Preliminary fixed tensioning wheel assembly 7; Interior hexagonal hole 10 is used for the tensioning of stretching wheel assembly 7, and allen wrench is inserted in the hole, and making stretching wheel assembly 7 is the center rotation with straight pin 8; Adjustment stretching wheel assembly 7 fits tightly with belt 13, applies the belt pretightening force.9 places install and fix bolt 11 at the adjustment arc; Fixing bolt 11 nut end faces and adjustment arc 9 place plane contact, fixing bolt 11 screws with the tapped hole 5 of Idle wheel support 1, realizes the fixing of stretching wheel assembly 7; And guarantee belt 13 tensionings, stretching wheel assembly 7 engine shaft to the planeness requirement.Belt 13 realizes that through the tension of stretching wheel assembly 7 driving pulley 14 drives driven pulley 12 and rotates.Through using this Idle wheel support 1, in very little space, realize the train layout, compact structure is saved the space, need not rotate annex adjustment train, has reduced the installation difficulty of annex.The utility model is used for fixing the Idle wheel support through through hole 2, through hole 3, through hole 6, and tapped hole 5 is used to install stretching wheel assembly 7 with pin-and-hole 4, saves the space, realizes the adjustment of train.This Idle wheel support successfully is used for forerunner, back drive engine, in less space, can realize the adjustment and the tensioning of belt, and compact structure need not rotate annex adjustment train, has reduced the installation difficulty of annex.
