Abstract
The utility model discloses a sealing structure for a transmission shaft of a speed reducer, which comprises sealing rings and at least two annular grooves arranged on a shaft end cover and/or the transmission shaft. The shaft end cover is movably matched with the transmission shaft; the sealing rings are arranged at one side of the shaft end cover and/or the transmission shaft, and the annular grooves are arranged at the other side of the shaft end cover and/or the transmission shaft; or the sealing rings and the annular grooves are arranged on the shaft end cover and/or the transmission shaft at intervals. As a plurality of sealing grooves and sealing rings are arranged between the transmission shaft and the shaft end cover, lubricating oil is subjected to multiple resistances in the process of leaking, and the effect of nearly zero leakage is finally reached. The sealing structure has the characteristics of simple structure, easiness in machining and manufacturing, long service life, low cost, good sealing effect and the like.
Description
Technical field
The utility model relates to the sealing configuration of transmission shaft, is specifically related to the sealing configuration of transmission shaft in a kind of retarder.
Background technique
Retarder of the prior art all needs to install additional seal ring between transmission shaft that stretches out cabinet and hubcap, the sealing circle is used to prevent that the oil leakage in the cabinet from coming out, simultaneously also can prevent that dust or dirt from entering in the cabinet of retarder.Because in the prior art, the seal ring that is installed between transmission shaft and the hubcap has only one, and great majority are the O RunddichtringO, and this sealing configuration sealing effect is poor, and lack working life, are difficult to reach prevent oil leak or the effect of oozing out.So be necessary in the existing retarder between transmission shaft and the hubcap sealing configuration improve.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, designs the sealing configuration of transmission shaft in the retarder of a kind of simple in structure, good sealing effect, long service life.
For achieving the above object, the technical solution of the utility model provides the sealing configuration of transmission shaft in a kind of retarder, it is characterized in that described sealing configuration comprises seal ring and at least two circular grooves that are arranged on hubcap and/or the transmission shaft, between described hubcap and the transmission shaft movingly.
Wherein optimized technical scheme is, described seal ring has 2～3.
Optimized technical scheme comprises that also described circular groove is the U-shaped opening slot or is spiral chute.
Optimized technical scheme comprises that also described seal ring is arranged on hubcap and/or transmission shaft one side, and described circular groove is arranged on the opposite side of hubcap and/or transmission shaft.
Optimized technical scheme comprises that also described seal ring and circular groove respectively are arranged on hubcap and/or the transmission shaft.
Optimized technical scheme comprises that also described seal ring and circular groove are arranged on the hubcap.
Optimized technical scheme comprises that also described seal ring and circular groove are arranged on the transmission shaft.
Optimized technical scheme comprises that also described seal ring is arranged on the hubcap, and described circular groove is arranged on the transmission shaft.
Advantage of the present utility model and beneficial effect are: because the utility model is provided with multiple-sealed groove and seal ring between transmission shaft and hubcap, make its lubricant oil run into multiple resistance in the process that leaks, finally reach the effect near zero leakage.Owing in the groove of seal groove and U-shaped opening slot seal ring, can hold lubricant oil, this lubricant oil both can play lubricated effect, also can play the effect of lubricant oil that stop, also can stop cabinet outer dust or dirt to enter in the cabinet simultaneously to external leakage.The sealing structure has simple in structure, is easy to manufacturing, and long service life is with low cost, characteristics such as good sealing effect.
Description of drawings
Fig. 1 is the sealed structural representation of transmission shaft in the utility model retarder.
Among the figure: 1, hubcap; 2, transmission shaft; 3, seal ring; 4, circular groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The utility model is the sealing configuration of transmission shaft in a kind of retarder, and the sealing structure comprises seal ring 3 and at least two circular grooves 4 that are installed on hubcap 1 and/or the transmission shaft 2, between described hubcap 1 and the transmission shaft 2 movingly.
In the utility model, described seal ring 3 can be equipped with 2～3; Described circular groove 4 can select for use the U-shaped opening slot or for spiral chute; Described seal ring can be arranged on hubcap 1 and/or transmission shaft 2 one sides, and described circular groove 4 is arranged on the opposite side of hubcap 1 and/or transmission shaft 2; Can also adopt described seal ring 3 and circular groove 4 respectively are arranged on technological scheme on hubcap 1 and/or the transmission shaft 2.
In the utility model, described seal ring 3 all can be arranged on the hubcap 1 with circular groove 4.Also described seal ring 3 all can be arranged on the transmission shaft 2 with circular groove 4; Described seal ring 3 can also be arranged on the hubcap 1, described circular groove 4 is arranged on the transmission shaft 2.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
