Abstract
The utility model discloses a seal ring for a motor rotor shaft; the seal ring comprises a disk-shaped seal ring body with an installation hole in the center; a seal sleeve extends from one side of the seal ring body along the installation hole; a rotor shaft is arranged in the seal sleeve; and at least one round of convex seal strips extend from the side wall of at least one side on the seal ring body along a circumferential direction. The seal ring for the motor rotor shaft is in an integrated structure of the seal sleeve and the seal ring body, the seal cylinder is used for sealing a joint between the rotor shaft and a motor box body, the motor box body and a gearbox body are sealed through the convex seal strips on the seal ring body, so that not only are the processing and the installation convenient but also a sealing effect is good.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of seal ring that encapsulate electric rotors axle and deceleration box are sealed of being used for.
Background technique
At present, when the rotor shaft of motor connects reducing gear, because of wanting lubricating oil filling in the deceleration box; In order to prevent that lubricant oil from getting in the motor in deceleration box, need between rotor axis of electric and speed reducer casing, seal arrangement be installed, traditional sealing means is; On motor case body, offer mounting groove, the O RunddichtringO is installed in the mounting groove, on rotor shaft, install the standard seal pad simultaneously additional; This structure exists manufacturing procedure complicated; Inconvenient installation, the long-term and rotor shaft friction of sealing effect difference and sealing gasket very easily damages the shortcoming of rotor shaft.
The model utility content
The purpose of the utility model is to provide a kind of seal ring that is used for rotor axis of electric, its have easy to process, be convenient to install, the characteristics of good sealing effect, effectively solved the problem that sealing exists between the rotor axis of electric and reducing gear in the existing technology.
The purpose of the utility model is to realize through following technological scheme:
A kind of seal ring that is used for rotor axis of electric; It comprises the seal ring body in the form of annular discs of center mounting holes; Said seal ring body upper edge mounting hole is extended with seal sleeve to a side, and its circumferencial direction of sidewall upper edge of at least one side extends at least one circle sealed batten on the said seal ring body.
Especially, offer mounting groove on the end outer wall of said seal sleeve, mounting spring circle in the said mounting groove.
Especially, the two ends inwall of said seal sleeve is all established the chamfering of being convenient to install rotor shaft.
Especially, be coated with inserts in the said seal ring body.
Especially, said sealed batten is arranged on the sidewall that is extended with seal sleeve on the seal ring body.
Especially, said sealed batten is set to one, and its excircle along the seal ring body is arranged.
The beneficial effect of the utility model does; The said seal ring existing technology that is used for rotor axis of electric is compared the integrative-structure that adopts seal sleeve and seal ring body; Utilize seal sleeve that the connecting part of rotor shaft and motor case body is sealed; Utilize the sealed batten on the seal ring body to make motor case body and speed reducer box sealing, not only easy to process, be convenient to install; And good sealing effect.
Description of drawings
Fig. 1 is the sectional drawing of the seal ring of the rotor axis of electric that provides of the utility model embodiment 1;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and through embodiment.
See also Fig. 1 and shown in Figure 2, Fig. 1 is the sectional drawing of the seal ring of the rotor axis of electric that provides of the utility model embodiment 1; Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
In the present embodiment; A kind of seal ring that is used for rotor axis of electric comprises the seal ring body 1 in the form of annular discs of center mounting holes; Be coated with the inserts 7 that increases bulk strength in the said seal ring body 1; And said seal ring body 1 upper edge mounting hole is extended with seal sleeve 2 to a side, be extended with on the said seal ring body 1 seal sleeve 2 a sidewall extend a circle sealed batten 3 along its excircle direction.
Offer mounting groove on the end outer wall of said seal sleeve 2, mounting spring circle 4 in the said mounting groove, the effect of tightening up is played in the end of 4 pairs of seal sleeves 2 of said spring ring, so that fit tightly between seal sleeve 2 and the rotor shaft 5.
The two ends inwall of said seal sleeve 2 is all established the chamfering 6 of being convenient to install rotor shaft 5.
The said seal ring that is used for rotor axis of electric is sheathed on rotor shaft 5 through mounting hole; Seal through the connecting part of 2 pairs of rotor shafts of seal sleeve 5 with motor case body; When motor case body is connected with the speed reducer casing, make both realize good sealing simultaneously through sealed batten 3.
