Abstract
The utility model proposes a kind of oil resistant V-belts, including sandwich layer and the infantees layer being wrapped on the outside of sandwich layer, sandwich layer is made of the upper glue layer and primer layer shelved up and down, it is characterized in that, the both ends of the upper glue layer and primer layer intersection interface are provided with semi-circular recesses, semi-circular recesses extend along the length direction of V-belt, and oil-absorbing resin is filled in semi-circular recesses.The V-belt improves the oil resistivity of V-belt in the case where not changing core material rubber components by the way that oil-absorbing resin is arranged, and has many advantages, such as that low cost, effect are good.
Description
Technical field
The utility model relates to a kind of V-belts.
Background technique
V-belt is the transmission belt for power transmission between power device and transmission device.Three in currently available technology
Angle band mainly uses natural rubber/styrene-butadiene rubber, and the rubber cost is lower, but stability is poor, is in the ring of heavy wool for a long time
In border, quickly can aging, the V-belt tensile property after ageing of rubber is greatly reduced, it is therefore desirable to have it is a kind of have oil resistivity compared with
Good V-belt.
Utility model content
In order to solve the problems, such as background technique, the utility model proposes a kind of oil resistant V-belt, the V-belts
The oil resistivity for improving V-belt by the way that oil-absorbing resin is arranged in the case where not changing core material rubber components, has low cost,
The advantages that effect is good.
The utility model adopts the following technical solution:
A kind of oil resistant V-belt, including sandwich layer and the infantees layer that is wrapped on the outside of sandwich layer, sandwich layer is by the gluing shelved up and down
Layer and primer layer composition, which is characterized in that the both ends of the upper glue layer and primer layer intersection interface are provided with semi-circular recesses, and half
Circular groove extends along the length direction of V-belt, and oil-absorbing resin is filled in semi-circular recesses.
The cross section of upper glue layer and primer layer is trapezoidal, and the bottom of upper glue layer is identical as the upper bottom length of primer layer.
Multiple tracks polyester cord is provided in upper glue layer, multiple tracks polyester cord is generally aligned in the same plane.
The radius of semi-circular recesses is the 1/7-1/5 of V-belt profile height.
The lateral surface of oil-absorbing resin is flush with the infantees layer for being wrapped in sandwich layer side.
The beneficial effects of the utility model are: oil-absorbing resin is provided with by the side in V-belt, so that three
Angle band is applied to V-belt side oil when operating is gradually absorbed by oil-absorbing resin, so as to avoid oil to V-belt infantees
The erosion of layer, extends the service life of V-belt.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing
Fig. 1 is the cross section structure schematic diagram of oil resistant V-belt described in the utility model；
Specific embodiment
Explanation and specific embodiment are further described the utility model with reference to the accompanying drawing:
Embodiment 1
A kind of oil resistant V-belt, as shown in Figure 1, sandwich layer is by upper and lower including sandwich layer and the infantees layer 3 being wrapped on the outside of sandwich layer
Upper glue layer 1 and primer layer 2 composition shelved, the cross section of upper glue layer 1 and primer layer 2 be it is trapezoidal, and the bottom of upper glue layer 1 with
The upper bottom length of primer layer 2 is identical, and multiple tracks polyester cord is provided in upper glue layer, and multiple tracks polyester cord is generally aligned in the same plane.On
The both ends of 2 intersection interface of glue-line 1 and primer layer are provided with semi-circular recesses 6, semi-circular recesses 6 along V-belt length direction
Extending, the radius of semi-circular recesses 6 is the 1/7-1/5 of V-belt profile height, it is filled with oil-absorbing resin 5 in semi-circular recesses 6,
The lateral surface of oil-absorbing resin 5 is flush with the infantees layer 3 for being wrapped in sandwich layer side.
Side in V-belt is provided with oil-absorbing resin, so that being applied to triangle when V-belt operates
Oil with side is gradually absorbed by oil-absorbing resin, and the erosion so as to avoid oil to V-belt infantees layer extends V-belt
Service life.
It will be recognized by those skilled in the art, can be to above-mentioned under the premise of without departing from protection scope of the present invention
Embodiment is carry out various modifications, changes and is combined, and thinks that this modification, variation and combination are the models in originality thought
Within enclosing.
