Abstract
The utility model relates to a novel-structure joined V-belt for a belt gear, solving the problems that the prior joined V-belt is easy to generate heat and has short service life. The concrete structure improvement is as follows: a coating layer is arranged on the V-shaped lateral surface of each V-belt and a stretching glue film is arranged on the top of the V-belt; and over two V-belts are directly connected with the stretching glue film on the top of each V-belt through connecting layers on the upper surfaces of the V-belts to form a joined V-belt. The novel-structure joined V-belt has the advantages that: the glue of the connecting layers on the joined V-belt directly adheres to the stretching glue film (namely a polychloroprene layer) on the top of the single V-belt, thereby the adhesive power is increased hundreds of times; and the improved joined V-belt has reduced bending stress, reduced heat generation, slow temperature rise, difficulty in premature cure and prolonged service life.
Description
Technical field
The utility model relates to belt gear joint group V-shape belt.
Background technique
Joined v-belt is the V band group that the end face of several identical classical V-belts or narrow V belt combines as a whole.Be that each bar V strip length unanimity has good integrity by one group of band of same material and once-through sulfuration, each band is stressed evenly, operate steadily, so bearing capacity is higher, and the life-span is longer, is fit to high-power transmission.Joined v-belt (is example with 3HB1970) is to use as the associating device on combine-harvester, and when Idle wheel pressed down, adhesive tape began transmission, and when lifting on the Idle wheel, adhesive tape unclamps and stops transmission.When adhesive tape turns round, exist forward and back-flexing like this, flexural stress is bigger.The 3HB1970 of domestic production at present divides two kinds of situations substantially: first kind of major part can only be used half a year, or shorter; Another kind minority producer can use at least one year, but can use 2-3 seldom.
Existing joined v-belt 3HB1970 ubiquity two aspects problem: the one, single band and tie layer easily break away from, be single V band made-up belt to be carried out be unified into group again when producing joined v-belt, and the outermost surface of single band is the infantees that is soaked with glue, the intensity that connects depends on the Adhesion force of infantees and glue, although adopt the very high neoprene of Adhesion force, but still can not reach requirement; The 2nd, it is bigger to give birth to heat, and temperature is higher, and fall short of working life, and as can be seen, adhesive tape 8 straddles on driving wheel 6, the follower 9 from Fig. 2, when Idle wheel 7 presses down, and adhesive tape 8 beginning transmissions, when lifting on the Idle wheel 7, adhesive tape unclamps and stops transmission.When adhesive tape turns round, exist forward and back-flexing like this, flexural stress is bigger, and (infantees is the canvas that is made into by parallel and warp intersection 90 degree, and longitudinal flexible is relatively poor, and flexural stress increases, and gives birth to hot easily and single band upper surface is surrounded by infantees.
Summary of the invention
In order to increase the Adhesion force of single band, improve the working life of joined v-belt, the purpose of this utility model is: a kind of new structure joint group V-shape belt is provided.
The architecture advances scheme that realizes above-mentioned purpose is as follows:
New structure joint group V-shape belt comprises two above V-shape belts, and two above V-shape belts connect to form the joint group V-shape belt by the tie layer of upper surface; Every V-shape belt from top to bottom comprises upholds glue-line, strength layer and compression glue-line;
The V-arrangement outer side surface of described every V-shape belt is provided with the infantees layer, and end face is for upholding glue-line;
Described two above V-shape belts connect to form the joint group V-shape belt by the direct extension glue-line with every V-shape belt end face of the tie layer of upper surface.
Useful technique effect of the present utility model is embodied in following several aspect:
1, traditional joined v-belt structure glue that is tie layer and single V band outermost surface are that the infantees layer is bonding, and the structure after improving be tie layer glue directly with the extension glue-line bonding (being the neoprene layer) of single V band end face, increased the Adhesion force of hundred times.
2, the single V band of the joined v-belt structure after improvement end face is a glue, and the bending properties of glue is better than infantees greatly, and flexural stress is reduced, and gives birth to heat to reduce, and temperature rises slowly, is difficult for incipient scorch, the prolongation in working life.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the belt transmission structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, new structure joint group V-shape belt comprises three V-shape belts, and every V-shape belt from top to bottom comprises upholds glue-line 3, strength layer 4 and compression glue-line 5, and the V-arrangement outside bread of every V-shape belt is provided with infantees layer 2, and end face is for upholding glue-line 3;
Three V-shape belts tie layer 1 by upper surface directly with the extension glue-line 3 bonding joint group V-shape belts that connect to form of every V-shape belt end face.
Be with fatigue test method with (half-breadth) V band and GB/T12735-1991 farm machinery with V according to GB/T14829-1993 farm machinery.The utility model has carried out test of many times on multi-functional fatigue testing machine, natural running temperature is 85 degree, the test failure time is 144 hours, also meets the theory of " rubber industry handbook " adhesive tape part in working life: i.e. adhesive tape operating temperature rising 10 degree, the life-span reduces half.With the 3HB1970 that conventional construction is produced, natural running temperature is 105 degree, and the test failure time is 32 hours.
Claims (1)
1, new structure joint group V-shape belt comprises two above V-shape belts, and two above V-shape belts connect to form the joint group V-shape belt by the tie layer of upper surface; Every V-shape belt from top to bottom comprises upholds glue-line, strength layer and compression glue-line, it is characterized in that:
The V-arrangement outer side surface of described every V-shape belt is provided with the infantees layer, and end face is for upholding glue-line;
Described two above V-shape belts connect to form the joint group V-shape belt by the direct extension glue-line with every V-shape belt end face of the tie layer of upper surface.
