Description
Technical field
The present invention relates to mechanical transmission fields, particularly a kind ofly be used to transmit mechanokinetic joint group primer folder cloth formula V band.
Background technique
Joint group primer folder cloth formula V band generally is used in powerful machinery, and along with being widely used of machinery, service condition is harsh day by day, like the temperature in winters such as south poles, Russia all below-40 ℃.And mostly used joined v-belt material is natural rubber or neoprene at present; Effective serviceability temperature scope of natural rubber is-20 ℃～80 ℃, and effective serviceability temperature of neoprene is-30 ℃～100 ℃, surpasses this temperature range; Can descend significantly the working life of joint group primer folder cloth formula V band; Under-40 ℃ serviceability temperature, these two types of belts all follow the string, and the life-span also only has about 10 hours.Therefore mostly have to adopt expensive mechanical transmission at the outdoor powerful device of cold zone.
The disclosure of the Invention of publication number CN1370973A a kind of joined raw-edge V-belt and production method thereof, joined raw-edge V-belt is connected into integrative-structure side by side by the V more than two band, in V band set inside skeleton is arranged; V band bottom is a toothed region; Top is flat bottoms, and adjacent V band is into a single integrated structure through flat connection, and skeleton is arranged on toothed region and flat bottoms transition position; The V band is chloroprene rubber V band, and skeleton is polyester rigid line rope.This joined raw-edge V-belt is that neoprene is processed, and effectively serviceability temperature is-30 ℃～100 ℃, surpasses this temperature range, and can descend significantly the working life of joint group primer folder cloth formula V band.
Summary of the invention
It is narrower to the objective of the invention is to overcome the temperature range that has the joined v-belt use now; Surpass short defective of serviceability temperature scope life-span; A kind of joint group primer folder cloth formula V is provided band, and it can normally effective long-term works wider temperature range-40 ℃～121 ℃.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of joint group primer folder cloth formula V band; Said joint group primer folder cloth formula V band comprises the top layer of cloth from outside to inside successively, upholds layer, bonding layer and compression layer; The compression layer internal surface is that the middle part of burnishing surface and internal surface has V-shaped groove; Be distributed with framework layer in the said bonding layer, said compression layer is made up of with inboard primer canvas filler layer the main glue-line in the outside, and main glue-line connects bonding layer; Said primer canvas filler layer is made up of carcass and primer layer; Carcass is arranged by the primer layer devices spaced apart, and the said main gel kind of upholding layer, bonding layer and compression layer is an ethylene-propylene diene copolymer, and the adhesive plaster of carcass all is to be the cement dip processing of ethylene-propylene diene copolymer through the main gel kind in said top layer of cloth and the primer canvas filler layer.
Acting as of each layer of the present invention:

For the length that guarantees joint group primer folder cloth formula V band is even, the production procedure of adopting the moulding of whole tube, cutting back emery wheel to polish.
The mode of production of the present invention
Adopt the method for reverse wrap molding during moulding; That is: the two-layer top of bag subsides earlier layer of cloth 1 on metal mold wraps three layers of subsides again and upholds layer 2 film, wraps subsides one deck bonding layer 3 films afterwards; Twine framework layer 4; Bag pastes one deck bonding layer 3 films, and after bag pasted two-layer compression layer 5 films, last bag at interval pasted three layer compression layers, 5 adhesive plaster (forming primer canvas filler layer 52).
Top layer of cloth 1 is to form after the immersion treatment with adhesive plaster; Immersion treatment directly gets into baking oven under 100 ℃ ± 1 ℃ temperature after only needing to be immersed in top layer of cloth 1 or adhesive plaster in the rubber cement, and baking 2-3min gets final product, and film is all produced through mangler; The gap of control roller; Thickness 0.7-1.5mm, film cool off with cooling roll in calender line.
Sulfuration uses the flat gum cover of the vulcanization of rubber to carry out; That is: earlier by the technician on controlling computer, set curing parameter (temperature 160-180 degree, pressure 0.8-1.5Mpa, time 25-50min) again with the made-up belt of forming with metal mold; Hang on the platform of autoclave press; The flat gum cover of the good corresponding vulcanization of rubber of cover is pressed start button, and whole sulfidation is accomplished under the monitoring of computer automatically; The operator can not change the running parameter of sulfurizing pot, has guaranteed the uniformity of every product degree of cure.
The tensioning of horizontal pair of roller cutting machine is used in cutting, preestablishes cutting width and feed velocity, and the wolfram steel cylinder blade axially becomes the feed mode of 90 ° of vertical cuts with being with tube, and computer is controlled cutting automatically and accomplished.
Polishing uses horizontal automatic sander to carry out, and preestablishes the belt length and the polishing amount of feed, uses emery wheel to polish automatically.
