Description
Technical field
The utility model relates to mechanical transmission fields, particularly a kind ofly is 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 that the purpose of the utility model is to solve 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 ℃.
