Abstract

The utility model relates to a two-layer porous V-belt. Aiming at currently widely applied three-layer solid V-belt structures, two layers of materials, namely, a tensile body and a rubber, are adopted, and the boundary of the tensile body and the rubber is accurately set in a neutral layer position of a V-belt section, so that the tensile potential of the tensile body can be effectively improved, the slippage damage to the V-belt caused by multiple layers and dislocation movement produced during bending deformation of different materials is prevented; secondly, multiple groups of cylindrical holes are evenly formed in the rubber on the inner periphery of the V-belt, each group comprises 2-5 cylindrical holes arranged in parallel, and hole diameters, hole lengths and dimensions of each group of hole distances are related to the model of the belt, so that bending flexibility of the V-belt is increased, machining stress concentration of the V-belt is reduced, the weight of the V-belt is reduced, and the bending stress and the centrifugal tensile stress of the V-belt during transmission are reduced; in addition, a piece of covering cloth of the V-belt is made of a magnetic material, and the adsorption force between the V-belt and an iron belt pulley is increased except fixation of the two layers of materials, so that the effective tensile force and the transmission capacity of the V-belt can be improved.

Description

A kind of two-layer, porous type V band

Technical field

The utility model relates to a kind of two-layer, porous type V band, specifically, relate to a kind of can improve V with bearing capacity, alleviate V with weight, reduce flexural stress, the centrifugal tensile stress of V band, increase V and be with effective driving force, prevent the destructions such as material dislocation that V band causes due to moment of flexure, bending deflection, slippage, fracture.

Background technique

Classical V-belt transmission is a kind of kind of drive extensively adopting in mechanical industry, and the classical V-belt transmission using in a large number in engineering machinery is at present three layers, solid formula V band.Because the transmission of V band is friction driving, it is that colloid, mesosphere are tension element that its V band is mostly designed to upper and lower layers.This V band structure, because V only has one with the neutrosphere of section, it depart from often tension element center and without any rule can say, when V band is in the time producing moment of flexure, bending deflection through belt wheel, can make tension element and between these two separating surfaces of colloid, all easily produce relative to dislocation and move up and down, cause the sliding rupture of V band.Be that current V is single with the material of tension element again, because position is limit, the material of tension element is relatively less, effective rate of utilization is low, a little less than V is with bearing capacity.Flexible poor, the Heavy Weight of the bending of solid formula V band in addition, flexural stress, centrifugal tensile stress are large, the easily generation fatigue ruption of V band.

Model utility content

For existing three layers, the shortcomings and deficiencies of solid formula classical V-belt transmission, the utility model provides a kind of two-layer, porous type V band, and it comprises tension element, colloid and magnetic infantees.Described cross-sectional configuration two-layer, porous type V band is two-layer different materials, the outer hard material that adopts tension, and internal layer is colloid, tension element and the colloid of V band are integrated with magnetic infantees bag.The tension element of V band and the separatrix of colloid are set in the neutrosphere position of V with section exactly, can effectively prevent that V is with due to bending moment, bending deflection, make to produce relative to dislocation and move between tension element and colloid, cause the sliding rupture of V band, can change the single-mode of tension element material simultaneously, strengthen tension element volume, effectively utilize the drawing-resistant function of tension element, increase the bearing capacity of V with transmission.Secondly, colloid has uniform array cylindrical hole, arranging 2-5 equidimension cylindrical hole for every group, size between the long and every group of pitch-row in aperture and hole is relevant with the model of band, its objective is that the bending flexibility, the minimizing V that increase V and be with are with the stress of processing to concentrate, alleviate the weight of V band, the counter-bending ability that increase V is with and flexural stress, the centrifugal tensile stress of minimizing V with transmission.The infantees of V band adopts magnetic material manufacture in addition, and tension element and colloid bag are integrated, and except fixing materials at two layers, has also increased the adsorption force of V band with ferrous material belt wheel, thereby has improved effective tension and the transmission capacity of V band.In order to ensure the Security with transmission and transmission quality, V belt transmission system is adopted to closed installation and transmission.

The beneficial effects of the utility model

1, improve the utilization ratio of V with tension element material, excavated the potential bearing capacity of V with transmission;

2, changed the single-mode of V with tension element material;

3, can effectively prevent the relative dislocation sliding rupture that produces between tension element and colloid;

4, increase the bending flexibility of V band, reduced the flexural stress of V band, effectively raised the counter-bending ability of V band;

5, alleviate the weight of V band, reduced the centrifugal tensile stress of V band;

6, increase the adsorption force of V band with ferrous material belt wheel, improved the effective tension of V band, improved the transmission capacity of V band.
