Description
Technical field
The utility model is related to the tensioning apparatus of a kind of belt or chain, specifically a kind of stretcher.
Background technology
Belt or chain have a wide range of applications in transmission process, and belt or chain can become pine in long-term work
De-, tensile force is not enough, so as to cause belt slippage or Timing Belt to occur to jump tooth, de- tooth, or chain-loose, comes off, and influences
Normal work.
The content of the invention
The utility model is regarding to the issue above, there is provided a kind of stretcher, and the stretcher can provide appropriate to belt or chain
Tensile force, keep suitable tensioning degree.
According to the technical solution of the utility model：A kind of stretcher, it is characterised in that：Including bearing, in the chute of bearing
Nut slider is equipped with, a guide pad is respectively provided with corresponding to nut slider both sides on bearing, screw rod runs through along its length
Bearing chute is set, and nut slider is connected with screw flight, and screw rod outer end is pressed on bearing by briquetting, on the nut slider
Fixed shaft assembly, tensioning wheel is rotated and is arranged on the shaft assembly.
Used as further improvement of the utility model, the shaft assembly includes support shaft, holding screw, bearing and back-up ring,
Support shaft is fixed on nut slider, and tensioning wheel is rotationally connected with support shaft by bearing, and bearing is fixed by retainer ring spacing, gear
Circle is fixed on support shaft by holding screw.
Used as further improvement of the utility model, the nut slider both sides form symmetrical projection, raised
It is supported on bearing, and is compressed by corresponding guide pad.
Used as further improvement of the utility model, both sides are symmetrical arranged engaging lug to the bearing in the width direction.
It is of the present utility model to have technical effect that：The utility model product provides the pressure for pointing to belt or chain, tensioning
Wheel and Timing Belt directly contact, and guide rail is directly contacted with timing chain, they will while with belt or chain operation
The pressure that stretcher is provided applies thereon, to make them keep suitable tensioning degree.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the sectional view at the utility model center in the width direction.
Fig. 3 is tensioning wheel side of the present utility model end view.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 3, including shaft assembly 1, support shaft 1-1, holding screw 1-2, bearing 1-3, back-up ring 1-4, bearing 2, guiding

As shown in Fig. 1 ~ 3, the utility model is a kind of stretcher, including bearing 2, and spiral shell is equipped with the chute of bearing 2
Female sliding block 7, a guide pad 3 is respectively provided with bearing 2 corresponding to the both sides of nut slider 7, and screw rod 5 runs through bearing 2 along its length
Chute is set, and nut slider 7 is threadedly coupled with screw rod 5, and the outer end of screw rod 5 is pressed on bearing 2 by briquetting 4, the nut slider 7
Upper fixed shaft assembly 1, tensioning wheel 6 is rotated and is arranged on the shaft assembly 1.
Shaft assembly 1 includes support shaft 1-1, holding screw 1-2, bearing 1-3 and back-up ring 1-4, and support shaft 1-1 is fixed on nut
On sliding block 7, tensioning wheel 6 is rotationally connected with support shaft 1-1 by bearing 1-3, and bearing 1-3 is by the spacing fixations of back-up ring 1-4, back-up ring
1-4 is fixed on support shaft 1-1 by holding screw 1-2.
The both sides of nut slider 7 form symmetrical raised 7-1, and raised 7-1 is supported on bearing 2, and by corresponding
Guide pad 3 is compressed.
Both sides are symmetrical arranged engaging lug 8 to bearing 2 in the width direction.
The utility model provides the pressure for pointing to belt or chain, tensioning wheel and Timing Belt directly contact, and guide rail is straight
Connect and contacted with timing chain, the pressure that they kick stretcher while with belt or chain operation applies thereon, to make
They keep appropriate tensile force.
When in use, the utility model product is fixed in equipment by engaging lug 8, rotary screw 5, by screw rod 5
Nut slider 7 is driven, drives tensioning wheel 6 to move the tensioning operation realized for belt by nut slider 7.
