Abstract
The invention discloses a sealing structure for a transmission shaft in a speed reducer. The sealing structure comprises sealing rings which are arranged on a shaft end cover and/or a transmission shaft in movable fit and at least two annular grooves; the sealing rings are arranged on one side of the shaft end cover and/or the transmission shaft; the annular grooves are formed on 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. Because a plurality of sealing grooves and sealing rings are arranged between the transmission shaft and the shaft end cover, lubricating oil meets multiple resistance in the spilling process, and the effect close to zero leakage is achieved finally. The invention has the characteristics that: the sealing structure is simple, easy to process and manufacture, long in service life, low in cost, good in sealing effect and the like.
Description
Technical field
The present invention relates to the sealing configuration of transmission shaft, be 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.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the prior art, design 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, technological scheme of the present invention provides the sealing configuration of transmission shaft in a kind of retarder, it is characterized in that, described sealing configuration comprises hubcap and/or the seal ring on the transmission shaft and at least two circular grooves that are arranged on 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 invention and beneficial effect are: because the present invention 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 retarder of the present invention.
Among the figure: 1, hubcap; 2, transmission shaft; 3, seal ring; 4, circular groove.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only are used for technological scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
The present invention is the sealing configuration of transmission shaft in a kind of retarder, and the sealing structure comprises hubcap 1 and/or the seal ring 3 on the transmission shaft 2 and at least two circular grooves 4 that are installed in movingly.
In the present invention, 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 present invention, 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 invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
