Mechanical-hydraulic bonding composite stepless speed regulating device

Abstract

The invention discloses a mechanical-hydraulic bonding composite stepless speed regulating device which comprises a support block (3), an input shaft (6), a disc spring (11), an outer friction plate (12), an inner friction plate (13), a planet wheel (16), a planet shaft (17), a sun wheel (18) and an output shaft (21); one end of the input shaft (6) is fixedly connected with the sun wheel (18), a planet transmission system is formed by the sun wheel (18), the plant wheel (16), the output shaft (21) and an inner gear ring (14), and the plant wheel (16) is connected with the planet shaft (17) into a whole through a planet bearing (25) and arranged on the shaft surface in closed space of the output shaft (21); the inner gear ring (14) is meshed with the planet wheel (16) through an internal tooth, and the other end of the inner gear ring is assembled with the outer friction plate (12) through an internal spline; and the inner friction plate (13) is fixed between the support block (3) and a link stopper (15) through a pin roll (10). The device has the advantages of reasonable, simple and compact structure and long service life, and is suitable for speed regulation and soft start of high-power equipment.

Description

technical field [0001] The invention relates to a stepless speed regulating device, in particular to a mechanical-liquid-viscosity compound stepless speed regulating device which utilizes liquid viscosity or shearing force to transmit power, and is suitable for high-power motors such as fans, water pumps and belt conveyors. The speed regulation and soft start process of the equipment. Background technique [0002] Liquid viscous transmission (referred to as liquid viscous transmission) is a new form of fluid transmission developed from abroad in the mid-1970s. It is based on Newton's law of internal friction and uses the shearing action of the oil film to transmit torque. By changing the oil film thickness control The size of the transmitted torque is characterized by high speed regulation sensitivity and good stability. The output speed can be adjusted steplessly within the range of 0-100%. It is an effective means to realize energy saving and consumption reduction of mecha...
