Abstract
A labyrinth seal structure for a direct-coupled cycloidal pin gear speed reducer comprises a rotating ring, a stationary ring and a fastening screw, wherein a set of labyrinth seal structure is additionally arranged in an original speed-down cavity; the rotating ring is fixed on a speed reducer spindle; the stationary ring is fixed on an end cover flange plate; a labyrinth seal mode is adopted between the rotating ring and the stationary ring; and a skeleton oil seal structure is adopted between the end cover flange plate and the speed reducer spindle. According to the utility model, the labyrinth seal structure is directly arranged in the speed-down cavity, is reasonable in design, convenient for installation, good in sealing performance, free from lubricant leakage and durable in use, and can not reduce sealing effect under the influence of high temperature as the labyrinth seal structure is made of a carbon steel material.
Description
Technical field
The utility model relates to a kind of labyrinth seal structure of direct connected type cycloid pin wheel speed reducer.
Background technique
A kind of direct connected type cycloid pin wheel speed reducer is arranged in the decelerator series that uses at present.The characteristics of this speed reducer are that motor and speed reducer share a main shaft and an end cap flange plate, and outside framework oil seal is fixed on the end cap flange plate, and motor cavity and speed reducer chamber are separated and seal.This outside framework oil seal is quality of rubber materials, and is cheap, but non-refractory, easily aged deterioration; After using a period of time, the outside framework oil seal hardening, sealing effect descends, and the lubricant oil steam of vaporization leaks in motor cavity from velocity-reducing chamber, affects the normal operation of equipment.
The model utility content
For the existing deficiency of original technology, the utility model provides a kind of labyrinth seal structure of direct connected type cycloid pin wheel speed reducer.This labyrinth seal structure is simple, and is easy for installation, and sealing effect is good, can use for a long time.
The purpose of this utility model is to realize like this, the labyrinth seal structure of direct connected type cycloid pin wheel speed reducer, comprise rotating ring, stationary ring and set screw, it is characterized in that: increase by a cover labyrinth seal structure in original velocity-reducing chamber, rotating ring is fixed on the speed reducer main shaft, stationary ring is fixed on the end cap flange plate, is between rotating ring and stationary ring labyrinth seal to be provided with outside framework oil seal between end cap flange plate and speed reducer main shaft.
The utility model compared with prior art advantage is as follows:
1, this labyrinth seal is directly installed in velocity-reducing chamber, on the end cap flange plate processing four fixedly the tapped hole of stationary ring get final product, reasonable in design, easy for installation.
2, this labyrinth seal structure good seal performance, non lubricant oil leaks.
3, carbon steel material is adopted in this labyrinth seal, can not be subjected to temperatures involved and reduces sealing effect, and is durable in use.

Fig. 2 is labyrinth seal movable ring structure figure;
Fig. 3 is labyrinth seal static-ring structure figure;
1. rotating ring, 2. stationary ring, 3. set screw, 4. stationary ring flat screw, 5. speed reducer main shaft, 6. end cap flange plate, 7. outside framework oil seal.
Embodiment
As shown in Figure 1, the utility model discloses a kind of labyrinth seal structure of direct connected type cycloid pin wheel speed reducer, comprise rotating ring 1, stationary ring 2 and set screw 3, it is characterized in that: increase by a cover labyrinth seal structure in original velocity-reducing chamber, rotating ring 1 is fixed on speed reducer main shaft 5, stationary ring 2 is fixed on end cap flange plate 6, is between rotating ring 1 and stationary ring 2 labyrinth seal to be provided with outside framework oil seal 7 between end cap flange plate 6 and speed reducer main shaft 5.The utility model rotating ring 1 is fixed on speed reducer main shaft 5 by retaining screw 3; Stationary ring 2 is fixed on end cap flange plate 6 by four flat screws 4; And near outside framework oil seal 7.By labyrinth seal and outside framework oil seal 7 double seals, guarantee that speed reducer has good sealing effect during the speed reducer operation.
