Abstract
The utility model discloses a cleaving type spinning belt pulley used on a crankshaft. The spinning belt pulley comprises a shaft sleeve, a leather groove and a rotary table, wherein, the rotary table adopts a 'V' shape so as to form the leather groove; the shaft sleeve is in welded connection with the rotary table; and a leather belt is movably connected with the leather groove. By adopting the technical scheme, the spinning belt pulley has the beneficial effects that compared with a cast iron belt pulley, the spinning belt pulley has the advantages of spinning processing (non-chip machining), light structure and material conservation, so that the spinning belt pulley has small moment of inertia, is a material-saving and energy-saving new product, has high production efficiency and high balance performance, and needs no balance treatment; the streamline of the material is not cut off, and the surface production adopts a manner of cold-work hardening, and the organizational density is increased, so that the intensity and the hardness of the surface of the pulley groove are increased, and the dimensional accuracy is improved; and the slip frequency between the triangular belt and the pulley groove is small, so that the belt has a long service life and a beautiful appearance. As the weight of the spinning belt pulley is lighter than that of the cast iron belt pulley, the spinning belt pulley greatly reduces the centrifugal force, prolongs the service life of the bearing and the crankshaft, and reduces vibrations of the whole machine when in use in high speed rotation process.
Description
Technical field
The utility model relates to component of machine, the particularly a kind of formula of riving spinning belt pulley that is used on the bent axle.
Background technique
Present cast iron belt pulley structure weighs, takes material, thereby rotary inertia is big, balance quality is bad, need do Balance Treatment, the slippage of vee belt and race is big, belt life is shorter relatively, can reduce the working life of bent axle in the high speed rotating process under action of centrifugal force, and the vibrations of complete machine are also bigger.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of formula of riving spinning belt pulley that is used on the bent axle.
Rotary pressure technology also is the metal spinning forming technique, by rotation make it force bearing point by put line by line to face, simultaneously give certain pressure and make metallic material along this direction distortion with flow and the technology of a certain shape of moulding in certain direction.Here, metallic material must have plastic deformation or mobile performance, rotary press modelling is not equal to plastic deformation, it is the complex process of collection plastic deformation and flow deformation, special needs to be pointed out is, our said mould pressing technology is not single shear spinning and conventional spinning, and it is both combinations.In engineering goods, how to save material and but can improve the quality of products, the weight that alleviates product but can increase the service life, it is that people pay close attention to that the manufacture cost of reduction product and energy consumption but can reduce machining period always, " V " texrope belt V wheel is purposes one of mechanical transmission part very widely, if can be significant by steel plate forming.Metal plate system belt pulley is compared with traditional cast iron belt pulley, can save material.By metal metal plate material drawn--the metal plate system spinning belt pulley of-mould pressing is the belt wheel structural type of up-to-date the best.This belt wheel not only possesses above-mentioned advantage, and non-environmental-pollution, especially in multiple engineering goods such as automobile, tractor, reaper, air compressor, be widely used, on the belt pulley spinning lathe of employing steel metal plate blank special use blank produced by putting line, being made to the dough model bending by line.
The formula of the riving spinning belt pulley that is used on the bent axle provided by the utility model comprises axle sleeve, skin groove and rotating disk, and rotating disk is designed to " V " type and constitutes the skin groove, and axle sleeve and rotating disk are welded to connect, and belt and skin groove flexibly connect.
Owing to adopted above technological scheme, the utlity model has following beneficial effect: the advantage that the spinning belt wheel is compared with cast iron belt pulley is (chipless machining) that adopts spinning process to make, light in structure, material saving, thereby rotary inertia is little are a kind of material, energy-conservation new new products of saving.The manufacturing efficiency height, balance quality is good, generally need not Balance Treatment.Because the material streamline is not cut off, the surface production flow harden, tissue density improves, and the intensity hardness of wheel rooved face is improved, and the dimensional accuracy height, and the slippage of vee belt and race is little, and belt life is long, and aesthetic in appearance.In use.Because of weight is lighter than cast iron belt pulley, in the high speed rotating process, greatly reduce centrifugal force, improved bearing, in the working life of bent axle, reduced the vibrations of complete machine.
