Abstract
A front bearing positioning structure of motor relates to a motor bearing structure, in particular to a front bearing positioning and fixing structure of a shaft extending end of a two-speed flame-proof asynchronous motor. The front bearing positioning structure of motor comprises a frame (1), a front end cap (2), a front inner cover (3), a ball bearing (4), a front outer cover (5), a washer (6), a fastening nut (7), an oil seal (8), a rotary shaft (9), a seal cover (10), an O-shaped seal ring (11), a connecting bolt (12) and a fixed bolt (13), and obviously improves the intact rate of the motor, improves the call back rate from 10% to 2%, can tolerate a certain impact force, is not easy to damage a bearing, reduces stoppage of work and mistake production, and eliminates the potential safety hazard of coal mine production in a certain extent.
Description
Technical field:
A kind of motor fore bearing location structure is a kind of motor reel bearing structure, and particularly development machine is located and fixed structure with double speed flame proof asynchronous motor shaft extension end fore bearing.
Background technology:
As everyone knows, development machine is used under the coal mine both at home and abroad, and environment is abominable, and the working face angle of inclination is big, and complete machine operation climbing capacity requires high, is fit to contain the certain density environment of methane and explosion gas; Use the structure of front end housing, inner cap, roller bearing, back-up ring, enclosing cover, bolted connection at present with its supporting similar motor, this structure power of having certain impact that is in operation, cause damage of bearings, the mistake of stopping work is produced and is happened occasionally, and brings hidden danger to the colliery safety in production.
Summary of the invention:
A kind of motor fore bearing of the utility model location structure goal of the invention is: manufacture and design a kind of and the diverse motor fore bearing of prior art location structure.
A kind of motor fore bearing of the utility model location structure is achieved in that by support, front end housing, preceding inner cap, ball bearing, preceding enclosing cover, packing ring, lock screw, oil sealing, armature spindle, seal cover, O-ring seals, connecting bolt and set bolt to be formed; Preceding inner cap, ball bearing, packing ring, lock screw, oil sealing, seal cover are sleeved on armature spindle shaft shoulder relevant position successively; Front end housing, preceding inner cap, preceding enclosing cover are combined into bearing chamber by the connecting bolt connection, and ball bearing outer ring and front end housing inner ring are equipped; Front end housing is installed on the support by set bolt is fastening; Support and front end housing binding site are installed O-ring seals; Screw lock screw compressing packing ring and reach fastening ball bearing.
The beneficial effect of a kind of motor fore bearing of the utility model location structure: the availability ratio that uses of motor obviously improves, repair rate is increased to 2% by 10%, tolerates certain impulsive force, is difficult for causing damage of bearings, reduce the mistake of stopping work and produce, eliminated Safety of Coal Mine Production hidden danger to a certain extent.
Description of drawings:
Accompanying drawing 1 is a kind of motor fore bearing of the utility model location structure principle of device schematic diagram
Among the figure: support (1), front end housing (2), preceding inner cap (3), ball bearing (4), preceding enclosing cover (5), packing ring (6), lock screw (7), oil sealing (8), armature spindle (9), seal cover (10), O-ring seals (11), connecting bolt (12), set bolt (13)
Embodiment:
A kind of motor fore bearing of the utility model location structure is by being made up of support (1), front end housing (2), preceding inner cap (3), ball bearing (4), preceding enclosing cover (5), packing ring (6), lock screw (7), oil sealing (8), armature spindle (9), seal cover (10), O-ring seals (11), connecting bolt (12) and set bolt (13); Preceding inner cap (3), ball bearing (4), packing ring (6), lock screw (7), oil sealing (8), seal cover (10) are sleeved on armature spindle (9) shaft shoulder relevant position successively; Front end housing (2), preceding inner cap (3), preceding enclosing cover (5) are combined into bearing chamber by connecting bolt (12) connection, and ball bearing (4) outer ring and front end housing (2) inner ring are equipped; Front end housing (2) is installed on the support (1) by set bolt (13) is fastening; Support (1) and front end housing (2) binding site are installed O-ring seals (11); Screw lock screw (7) compressing packing ring (6) and reach fastening ball bearing (4).
Claims (2)
1, a kind of motor fore bearing location structure is characterized in that: be made up of support (1), front end housing (2), preceding inner cap (3), ball bearing (4), preceding enclosing cover (5), packing ring (6), lock screw (7), oil sealing (8), armature spindle (9), seal cover (10), O-ring seals (11), connecting bolt (12) and set bolt (13); Preceding inner cap (3), ball bearing (4), packing ring (6), lock screw (7), oil sealing (8), seal cover (10) are sleeved on armature spindle (9) shaft shoulder relevant position successively; Front end housing (2), preceding inner cap (3), preceding enclosing cover (5) are combined into bearing chamber by connecting bolt (12) connection, and ball bearing (4) outer ring and front end housing (2) inner ring are equipped; Front end housing (2) is installed on the support (1) by set bolt (13) is fastening; Support (1) and front end housing (2) binding site are installed O-ring seals (11).
2, according to the described a kind of motor fore bearing location structure of claim 1, it is characterized in that: screw lock screw (7) compressing packing ring (6) and reach fastening ball bearing (4).
