Abstract
A belt pulley assembly comprises a belt pulley shaft, wherein the belt pulley shaft is connected with a simple and duplex chain wheel in a rotating mode, and one end of the simple and duplex chain wheel is fixedly connected with a large belt pulley. The simple and duplex chain wheel is a tubular piece with the outer cylindrical surface provided with a simple and duplex chain wheel body and a connecting flange, wherein the large belt pulley is fixedly connected with the simple and duplex chain wheel into a whole through the connecting flange, the inner walls of the two ends of the tubular piece are in interference fit with the outer circle of a bearing, the belt pulley shaft is in interference fit with the inner circle of a bearing, and a portion, between the two bearings, of the belt pulley shaft is sleeved with a partition sleeve. One end of the belt pulley shaft is provided with connecting threads and a cover type nut. The belt pulley assembly has the advantages of being flexible in combination method, simple in production process and low in manufacturing cost.
