Description
Technical field
This utility model relates to Timing Belt technical field, particularly relates to the polywedge bet that a kind of heat resistance is good.
Background technology
Polywedge bet refers to flat rubber belting as matrix, and its inner surface is placed with the ring-shaped rubber transmission of the most trapezoidal wedge
Band, its work surface is the side of wedge.Polywedge bet is relatively big with the contact area of belt wheel and frictional force, and load is more equal along the distribution of bandwidth
Even, thus transmission capacity is bigger；Owing to belt body is thin and light, flexible, rational in infrastructure, therefore working stress is little, can be at less band
Work on wheel.It is little that polywedge bet also has transmission vibration, smooth running, uses elongation little, and gear ratio is big and limit line speed is high
Feature, thus the life-span is longer.Additionally, the back side of polywedge bet also can transmission, and automatic tension regulator can be used so that transmission
More safe and reliable.Polywedge bet is particularly well-suited in the high-speed drive that structural requirement is compact, transmission power is big.Polywedge bet makes
Used time working temperature is higher, and easily generates heat during high-speed drive.And existing polywedge bet heat-resisting effect is poor, heat radiation effect
Fruit is the most poor, has influence on service life and the transmission efficiency of polywedge bet.
To this end, applicant carried out useful exploration and trial, have found result of the above problems, will be detailed below being situated between
The technical scheme continued produces under this background.
Utility model content
Technical problem to be solved in the utility model: provide a kind of heat-resisting effect good for the deficiencies in the prior art
The polywedge bet that heat resistance is good.
This utility model is solved the technical problem that to realize by the following technical solutions:
The polywedge bet that a kind of heat resistance is good, including annular belt body, between on the inner ring surface of described annular belt body, circumference is uniform
Every being provided with some triangular belt teeth, described wedge shape toothed profile of tooth end face is arc surface, circumferentially-spaced in the body of described endless belt sets
It is equipped with some pulling force heart yearns extended along body length direction, described endless belt, it is characterised in that the outer ring surface of described annular belt body
On be compounded with first thermal insulation layer being made up of ceramic fibre, the described toothed surface of some wedge shapes is compounded with one fine by pottery
The second thermal insulation layer that dimension is made.
In a preferred embodiment of the present utility model, the toothed height of described wedge shape is 1.2mm～9.8mm.
In a preferred embodiment of the present utility model, the toothed wedge of described wedge shape is away from for 1.6mm～9.4mm.
In a preferred embodiment of the present utility model, the toothed angle of wedge of described wedge shape is 40 °.
In a preferred embodiment of the present utility model, the arc radius of described wedge shape toothed profile of tooth end face is
0.3mm～0.75mm.
In a preferred embodiment of the present utility model, described wedge shape toothed bottom arc radius be 0.3mm～
0.75mm。
In a preferred embodiment of the present utility model, the thickness of described annular belt body is 3mm～17mm.
In a preferred embodiment of the present utility model, described pulling force heart yearn is the heart yearn being made up of ceramic fibre.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: due to the outer shroud of annular belt body
Being provided with first thermal insulation layer being made up of ceramic fibre on face, some wedge shapes are provided with one by ceramic fibre on toothed surface
The second thermal insulation layer made so that the heat-resisting effect of this polywedge bet is preferable, when working temperature is higher or rotating speed is higher, this practicality
Novel polywedge bet is not easy deformed damaged of generating heat.
Accompanying drawing explanation
