The utility model has the advantages that: the sealing performance is good, simple structure reduces friction torque, prolongs the life of motor.
Description
Technical Field
The utility model relates to an electromechanical device, concretely relates to seal structure of motor shaft.
Background
Select rubber for use to seal usually between motor shaft and the end cover, but the sealed friction that exists of contact, mechanical loss increase causes the efficiency of motor to reduce, makes the pivot take place wearing and tearing easily, produces certain heat, big noise, and leads to rubber wearing and tearing easily, and the clearance appears easily in the rubber after wearing and tearing, causes to seal not tight the oil leak that appears, if sealing performance is not good can lead to impurity such as water, dust to get into inside the motor, influences the normal use and the life of motor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough to above-mentioned prior art provides a motor shaft's seal structure, and sealing performance is good, and simple structure reduces friction torque.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a seal structure of motor shaft which characterized in that: including pivot, bearing, cylindricality front end housing, rear end cap, first sealed lid, the bearing sets up between cylindricality front end housing and pivot, the rear end cap terminal surface is equipped with cyclic annular mounting groove, the terminal insertion of cylindricality front end housing is in cyclic annular mounting groove, first sealed lid overlaps in the pivot, keeps away from a terminal surface and the counterbalance of cylindricality front end housing of pivot, it will the two fixed connection to set up the jump ring between cylindricality front end housing and first sealed lid, also can come the cooperation to be connected through setting up bolt and screw thread.
The utility model discloses further setting is: the terminal surface of first sealed lid is equipped with the mounting groove, install the sealed lid of second in the mounting groove, the sealed lid of second cup joints with the pivot, the sealed side of covering of second is equipped with cyclic annular seal groove, it keeps sealed second sealing ring sealed to enable the sealed lid of second and pivot to set in the cyclic annular seal groove.
The utility model discloses further setting is: the outer side surface of the cylindrical front end cover is provided with a coaxial sealing groove, and a first sealing ring is arranged in the sealing groove.
The utility model has the characteristics as above: a first sealing cover is arranged between the rotating shaft and the end cover to prevent impurities such as water, dust and the like from entering, and a second sealing cover is further arranged between the first sealing cover and the rotating shaft to increase the sealing effect of the structure, avoid friction generated by contact type sealing and avoid the reduction of the service life caused by the heating of the rotating shaft; different sealing rings are used for fixing the cylindrical front end cover and the second sealing cover respectively, so that the sealing structure can also achieve a good sealing effect under the working condition of the motor, and oil leakage is avoided.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1, the sealing structure of a machine rotation shaft includes a rotation shaft 1, a bearing 2, a cylindrical front end cover 3, a rear end cover 4, and a first sealing cover 5, wherein the bearing 2 is disposed between the cylindrical front end cover 3 and the rotation shaft 1. The end face of the rear end cover 4 is provided with an annular mounting groove, the tail end of the cylindrical front end cover 3 is inserted into the annular mounting groove, the outer side face of the cylindrical front end cover 3 is provided with a sealing groove which is coaxial, and a first sealing ring 7 is arranged in the sealing groove. The first sealing cover 5 is sleeved on the rotating shaft 1, one end face far away from the rotating shaft 1 is abutted to the cylindrical front end cover 3, and a clamp spring 9 is arranged between the cylindrical front end cover 3 and the first sealing cover 5 to fixedly connect the cylindrical front end cover and the first sealing cover. The terminal surface of first sealed lid 5 is equipped with the mounting groove, installs the sealed lid 6 of second in the mounting groove, and the sealed lid 6 of second cup joints with pivot 1, and the sealed 6 side of lid of second is equipped with cyclic annular seal groove, and cyclic annular seal inslot is put second sealing ring 8.
When in work: bearing 2 cover is in pivot 1, cup joints rear end cap 4 in the pivot 1, sheathes rear end cap 4 in the bearing 2 front end, sheathes first sealed lid 5 in the bearing 2 front, installs the sealed lid 6 of second in the mounting groove, imbeds sealing ring 8 in the cyclic annular seal groove of the sealed lid 6 of second, use the bearing heater heating earlier sealing ring 8 again imbed in the cyclic annular seal groove. The first sealing cover 5 is externally sleeved with the cylindrical front cover 3 which is fixedly connected with the first sealing cover through the clamp spring 9, and the first sealing ring 7 is embedded into the sealing groove after the tail end of the cylindrical front cover 3 is fixedly connected with the rear end cover 4 in an inserted mode. Impurities such as water, dust and the like in work are isolated by the first sealing cover and the second sealing cover.
