Embodiment Construction

[0067] In order to facilitate a better understanding of the content of the present invention, the present invention will be described in detail below in conjunction with the drawings. Since this embodiment is only an optimal embodiment and not the only way to achieve it, the present invention should protect the invention including this embodiment. widest range.

[0068] Such as figure 1 , 2 As shown in , 3, the present invention discloses a comprehensive self-cooling shaft seal system, which is applied to the shaft seal of the reducer. It is installed at the joint between the reducer shaft 62 and the chassis 8, and plays the role of sealing liquid. The system includes an end cover fixing assembly, a heat conduction and cooling ring 2 , a stationary auxiliary sealing ring 3 , a static liquid sealing friction ring 4 , a rotating liquid sealing assembly and a transmission key 61 on a crankshaft 62 . The rotary liquid seal assembly includes a rotary liquid seal friction ring 51 ...

Abstract

The invention discloses a comprehensive self-cooled shaft seal system. The comprehensive self-cooled shaft seal system is used for rotary sealing of a joint part between a speed reducer shaft and a machine box and comprises an end cover fixing assembly, a heat conduction and heat dissipation ring, a static auxiliary seal ring, a static sealing liquid friction ring, a rotary sealing liquid assembly and a driving key located on a shaft; the end cover fixing assembly comprises a fastener, a machine case seal ring, an end cover and a stop dowel; the rotary sealing liquid assembly comprises a rotary sealing liquid friction ring, an elastic and composite pressing component with the sealing function and an outer spiral groove driving base. According to the comprehensive self-cooled shaft seal system, the problems of the respiration effect of a framework oil seal and oil leakage caused by jittering of the speed reducer shaft due to the insufficient machining accuracy of the machining technology can be solved, and the service life of a shaft seal device can be greatly prolonged; the reasonable pressure design is adopted in a speed reducer with low rotation speed, and therefore the good effect that the shaft seal device of the speed reducer does not need to be replaced during the service life can be realized, and the production cost and the social resources can be saved.

Description

technical field [0001] The invention relates to a shaft seal system, in particular to a comprehensive self-cooling shaft seal system for the shaft end seal of a reducer. Background technique [0002] The reducer is a kind of transmission device, which is widely used in the modern machinery industry. The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. [0003] The reducer can be divided into single-stage and multi-stage reducer according to the number of transmission stages; according to the shape of the gear wheel, it can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear pulley reducer; according to the layout of the transmission It can also be divided into expansion type, shunt type and coaxial shaft reducer. However, these main transmission mech...
