Abstract
The utility model relates to a cold spinning belt pulley, which comprises a flange, a spoke and a hub, wherein the flange is provided with a plurality of multi-wedge type V-shaped slots, the center of an effective diameter of each V-shaped slot and the center of a shaft hole of the hub are concentric, the left and the right sides of each V-shaped slot are symmetrical, the center line thereof is perpendicular to the central axis of the hub, ring slots are arranged between the flange, the spoke and the hub, the spoke is provided with a plurality of arc-shaped slots, and the flange, the spoke and the hub are formed on a spinning machine by a steel plate through integrated cold spinning. The cold spinning single-stage coaxial multi-wedge type belt pulley has the advantages of excellent flexibility of flat belt wheels, simultaneously has the advantages of large transmission power of V-belt wheels, also can absorb impingement and vibration, has quiet operation comparing with the transmission of chains and gears, and has low noise.
Description
Technical field
The utility model relates to a kind of belt pulley, relates in particular to a kind of its wheel hub carries out cold spinning processing on spinning machine single-stage coaxle multi-wedge type pulley.
Background technique
Belt pulley is a modal transmission part in the mechanical transmission, generally partly is made up of wheel rim, former and wheel hub three, and type of belt drive such as flat belt transmission and V belt transmission are arranged.The flat belt transmission pulley, having overload can skid, protection safe in utilization, advantage such as flexible good, when velocity ratio is inaccurate, precision is not high, and service time is long, and flat belt can ownly extend when weather was hot, also can skid the generation power loss.The V-shape belt transmission pulley is provided with many flat rubber belting grooves, has the big advantage of transmission power, but because every belt is independent, be not conjuncted, each root belt stretching rate is different, rub proofness is also different, so the power when using is difficult to reach the power of design standard, precision is not high.
Along with social progress, such as modern product such as Vehicular air-conditioner compressors higher standard and the request are proposed technical performances such as the structure of the belt pulley of its use and precision, therefore need improve the structure of existing belt pulley, provide highi degree of accuracy, high performance belt pulley, to adapt to the requirement of modern high end product.
Summary of the invention
For overcoming the defective that existing belt pulley exists, the utility model provides a kind of single-stage coaxle multi-wedge type pulley by the integrated processing of cold spinning technology, to adapt to the requirement of modern high end product to belt pulley.
Technological scheme provided by the utility model is: a kind of cold spinning belt pulley, described belt pulley is the single-stage coaxle multi-wedge type pulley, comprise wheel rim, spoke and wheel hub, have many multi-wedge type V-type grooves on the described wheel rim, the effective diameter center of each bar V-type groove and the axis hole centres of wheel hub, every V-type groove bilateral symmetry, and its center line and wheel hub central axis are perpendicular, and described wheel rim, spoke and wheel hub are by sheet metal one cold spinning moulding on spinning machine.
Compared with prior art, the utlity model has beneficial effect is: 1, because the effective diameter center of each bar V-type groove of above-mentioned single-stage coaxle multi-wedge type pulley and the axis hole centres of wheel hub, every V-type groove bilateral symmetry, and its center line and wheel hub central axis center are perpendicular, and wheel rim, spoke and wheel hub are by sheet metal one cold moudling on spinning machine, thereby precision height, running steadily, both had the good advantage of flat tyre wheel ductility, has the big advantage of V belt wheel transmission power simultaneously, can absorb again simultaneously and impact and vibration, quiet than chain and gear transmission running, noise is little.2, adopt the whole spinning wheel hub of thin plate belt pulley, compare, overcome the distortion, the fatigue fracture that are brought because of welding with welding processing, improved fatigue strength greatly, simultaneously, the spinning wheel hub has increased the density of material behind spinning, thereby has improved the usability of part; Compare with traditional cast iron belt pulley, have material and economize (saving more than 70%), energy efficient, non-environmental-pollution, the manufacturing efficiency height, cost is low, and the product design that is processed is attractive in appearance, in light weight, rotary inertia is little, balance quality is good, noise is low, absorbs advantages such as the shock and vibration performance is good.3, whole processing on a special spinning machine does not need the multiple clamping mode transfer, realizes a clamping moulding, thereby guarantees the wheel rim of belt pulley and the concentric required precision of wheel hub.The utility model is particularly useful for multiple engineering goods such as automobile, tractor, reaper, air compressor.
The utility model is described in further detail below in conjunction with drawings and Examples.
