Abstract

The utility model relates to a combined sealing structure of a planetary wheel speed reducer. The front end of a gear ring is connected with a bearing seat; a motor seat extends into the bearing seat and the gear ring and is rotatablely matched with the bearing seat; a sealing ring is arranged at the inner side of a joint butted between the outer end of the bearing seat and the motor seat and is sheathed with a sealing ring; and a dustproof sealing ring is arranged at the outer side of the joint butted between the outer end of the bearing seat and the motor seat. The combined sealing structure has the advantages of reasonable and reliable structure, good sealing performance and long service life.

Description

The plane table thermoconductivity meter combined sealing structure
Technical field
The utility model relates to the sealing configuration of retarder, the combined sealing structure on specifically a kind of plane table thermoconductivity meter.
Background technique
In a kind of plane table thermoconductivity meter that is adopted on the existing crawler-type traveling equipment, only the seam inboard of docking between the outer end of bearing support and motor seat is provided with a road sealing device, this road sealing device is made up of seal ring and seal ring, seal ring is enclosed within on the seal ring, and both seam inboards of floating and docking between the outer end that is arranged on bearing support and the motor seat.Owing to the working environment that crawler-type traveling equipment is common is relatively abominable, the problem that the sealing configuration of above-mentioned this planet wheel decelerator in use exists is: the dust of working site and muddy water enter in the motor seat from the seam crossing between bearing support outer end and the motor seat easily, and then quicken the damage of seal ring and seal ring easily, in case seal ring and seal ring are damaged, dust and muddy water enter into retarder inside, then can quicken the damage of its inner components.Therefore, the sealing configuration of above-mentioned existing planet wheel decelerator exists the deficiency that sealing is not good, working life is short.
The model utility content
The purpose of this utility model is to provide a kind of plane table thermoconductivity meter combined sealing structure, the good airproof performance of this combined sealing structure.
For achieving the above object, the utility model adopts following scheme: the plane table thermoconductivity meter combined sealing structure, the front end of gear ring is connected with bearing support, the motor seat extend in bearing support and the gear ring, motor seat and bearing support are rotatably assorted, the seam inboard of docking between the outer end of bearing support and motor seat is provided with seal ring, is with seal ring on the seal ring, and dust-proof seal ring is equipped with in the seam outside of docking between the outer end of bearing support and motor seat.
By such scheme as seen, the seam inboard and the outside that the utility model docks between bearing support and motor seat are equipped with a road sealing device, have strengthened the sealing of seam crossing between the two so greatly, guarantee that dust and muddy water are difficult for entering in the work.
The utility model is rational in infrastructure, reliable, its good airproof performance, long service life.
Description of drawings
Accompanying drawing is the utility model one embodiment's a structural representation.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
In the plane table thermoconductivity meter combined sealing structure that the utility model provides, the front end of gear ring 1 is connected with bearing support 2, and motor seat 6 extend in bearing support 2 and the gear ring 1.The mode that motor seat and bearing support are rotatably assorted is: between motor seat 6 and bearing support 2 rolling bearing 7 is housed, the outer ring of rolling bearing 7, inner ring cooperate with bearing support 2, motor seat 6 respectively.The seam inboard of docking between the outer end of bearing support 2 and motor seat 6 is provided with seal ring 5, is with seal ring 4 on the seal ring.Dust-proof seal ring 3 is equipped with in the seam outside of docking between 6 in the outer end of bearing support 2 and motor.
By accompanying drawing as seen, the position in motor seat 6 outsides near bearing support 2 outer ends has ring-shaped step 6a, and dust-proof seal ring 3 lock rings are on this ring-shaped step 6a, and the outside of dust-proof seal ring 3 has " V " font groove 3a.The material of dust-proof seal ring 3 is a nitrile butadiene rubber.
