Problems solved by technology
However, during long-term use, the belt will slip and other phenomena will occur. Due to the long-term wear of the belt and the long-term operation, the wheelbase of the two sets of drive shafts will also decrease, resulting in loose belts, and in severe cases, belt deviation will occur. The situation seriously affects the normal operation of the equipment

Embodiment Construction
[0017] Such as Figure 1 to Figure 5 As shown, a reinforced pulley plays a protective role in the safety during use, and effectively avoids the possible deviation of the belt due to long-term use in the belt drive. The symmetrical structural design of the pulley makes installation more convenient and quicker, improving installation efficiency. The present invention includes a cylindrical main structure 1, and the center of the main structure 1 is provided with an assembly inner hole 2, and the assembly inner hole 2 is connected with the rotating shaft of the engine, and the rotation of the pulley is driven by the rotation of the engine. The assembly inner hole 2 is composed of two tapered holes with an angle of α. The tapered holes can make the fixed connection stronger and the installation more convenient. The side of the assembly inner hole 2 is provided with two full-through threaded holes 3, the center line of the two full-through threaded holes 3 is just the diameter of ...

The invention relates to the technical field of mechanical spare and accessory parts, in particular to a reinforced belt pulley. According to the technical scheme adopted by the invention, the reinforced belt pulley comprises a cylindrical main body structure; the center of the main body structure is provided with an inner assembly hole; the outer cylindrical surface of the main body structure is provided with a first belt groove, a second belt groove and a third belt groove; a first deflecting preventing surface is arranged on the side, close to the third belt groove, of the first belt groove, and a second deflecting preventing surface is arranged on the side, close to the third belt groove, of the second belt groove; and the largest cylindrical surface of the main body structure is larger than cylindrical surfaces where bosses on the two edges of the third belt groove are located, and the reinforced belt pulley is of a symmetrical structure. The reinforced belt pulley has the advantages that the convenience during assembling is improved through reasonable structure design, in addition, deflecting of belts during using is effectively prevented, and the stability and safety of the belt pulley during using are improved.
Description
technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a reinforced pulley. Background technique [0002] Belt pulleys, which belong to disc hub parts, are generally relatively large in size. The manufacturing process is generally based on casting and forging (generally, the larger size is designed by casting method, and the material is generally cast iron (good casting performance). Use less cast steel (the casting performance of steel is not good); generally the size is smaller, it can be designed as forging, and the material is steel). Pulleys are mainly used for long-distance transmission of power, such as small diesel engine power output, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, and some small horsepower motorcycles. Transmission, transmission of agricultural machinery power, air compressor, reducer, reducer, g...
