Abstract
A dustproof device comprises a turntable soleplate, an outer dustproof ring, a central gyrator, an outer dustproof ring holder, a gyration decelerating frame, a gyration decelerator, a gyration pinion, a bracket, an inner dustproof ring holder, and an inner dustproof ring. The utility model prevents dust from entering the gyration pinion by adding a secondary dustproof ring between the turntable soleplate and the bracket of the excavator.
Description
Technical field the utility model relates to the used dust guard of a kind of excavator.
Background technology concerning domestic excavator, at present between the turntable base plate of excavator and support because of not adding dust ring, a large amount of dusts has entered the revolution pinion, causes the revolution pinion often will change, turn round pinion life-span reduction etc.
The summary of the invention the purpose of this utility model provides a kind of processing ease, dust guard easy to maintenance.
The purpose of this utility model is achieved in that this device is by turntable base plate, outer dust ring, center steering body, dustproof ring support, rotary decelerating support, rotary reducer, revolution pinion, support, interior dustproof ring support, interior dust ring are formed outward, utilization adds the secondary dust ring between the turntable base plate of excavator and support, prevent that dust from entering the revolution pinion.
The cross section is in the described outer dust ring: middle porose bottom loudspeaker buckle shape
The interior cross section of dust ring is in described: with groove shape in the middle of the T shape
The utility model has the advantages that: can prevent that dust from entering on the revolution pinion, improve the application life of revolution pinion.
Be described further below in conjunction with drawings and Examples.
Description of drawings Fig. 1 is the front view of an embodiment of the present utility model
Among the figure: 1. turntable base plate; 2. outer dust ring; 3. center steering body; 4. dustproof outward ring support; 5. rotary decelerating support; 6. rotary reducer; 7. revolution pinion; 8. support; 9. interior dustproof ring support; 10. interior dust ring
