Abstract
The utility model discloses a three-phase asynchronous motor capable of bearing bidirectional axial force, which comprises a motor outer casing (1), a rotor, a stator, a junction box, a motor end cover (4), a spindle (2) and bearings (9) of the spindle. The bearings (9) are mounted between the spindle (2) and the motor end cover (4), and the spindle (2) is provided with a stop plate groove (8) and external threads matching with a stop nut (7). A stop plate (6) is mounted inside the stop plate groove (8) of the spindle (2) after the bearings (9) are sleeved onto the spindle (2), the stop nut (7) is mounted on the external threads, matching with the stop nut (7), of the spindle (2), and finally bearing outer end covers (5) are mounted. Additionally, the bearings adopt angle contact ball bearings mounted in pair. The three-phase asynchronous motor capable of bearing bidirectional axial force has the advantages of simple structure and strong universality, and is suitable for being adopted on motors of Y series and Y2 series.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of threephase asynchronous that can bear bi-directional axial power.
Background technology
At present known Y series threephase asynchronous, what bearing adopted is deep groove ball bearing, the axial force that this bearing can bear is very little, but the corollary equipment of a lot of motors often imposes unidirectional or two-way axial force to motor, make motor bearings under responsive to axial force, increase the friction and generate heat, shorten the working life of bearing greatly, and then make electric machine rotor sweep thorax, burn out motor.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can either bear radial force, can bear the stressed threephase asynchronous that can bear bi-directional axial power of bi-directional axial again.
The purpose of this utility model is achieved by following technical proposals: comprise motor casing, rotor, stator, and terminal box, End cover for motor, main shaft and bearing thereof, described Bearing Installation is between main shaft and End cover for motor; The external screw thread that described main shaft is provided with the stop film trap and mates with the retainer nut; After described bearing holder (housing, cover) is contained on the main shaft, locking plate is installed in the stop film trap of main shaft, on main shaft and external screw thread retainer nut coupling the retainer nut is installed, the bearing outer end cap is installed at last.
Described bearing adopts the angular contact ball bearing of mounted in pairs.
Compared with prior art, the utlity model has following advantage: simple in structure, highly versatile.Be suitable on Y, Y2 serial motors, adopting.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram;
Fig. 2 is the local structure for amplifying schematic diagram of the K of Fig. 1.
Among the figure: the 1-motor casing, the 2-main shaft, 3-bearing inner end cap, the 4-End cover for motor, 5-bearing outer end cap, the 6-locking plate, 7-retainer nut, 8-brakes film trap, 9-bearing.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to accompanying drawing, the utility model comprises motor casing 1, rotor, stator, and terminal box, End cover for motor 4, main shaft 2 and bearing 9 thereof, described bearing 9 are installed between main shaft 2 and the End cover for motor 4; The external screw thread that described main shaft 2 is provided with stop film trap 8 and mates with retainer nut 7; After described bearing 9 is sleeved on the main shaft 2, locking plate 6 is installed in the stop film trap 8 of main shaft 2, on main shaft 2 and external screw threads retainer nut 7 coupling retainer nut 7 is installed, bearing outer end cap 5 is installed at last.
Described bearing adopts the angular contact ball bearing of mounted in pairs.
Angular contact ball bearing can bear radial load and axial load simultaneously.Can under high rotational speed, work.Contact angle is big more, and axial carrying capacity is high more.High accuracy and high-speed bearing are got 15 degree contact angles usually.Under responsive to axial force, contact angle can increase.Single-row angular contact ball bearing can only bear the axial load of a direction, when bearing radial load, will cause additional axial force.And can only restrictive axes or shell in the axial displacement of a direction.If duplex is installed in pairs, make the outer ring of pair of bearings relative, promptly wide end surface is to wide end surface, and narrow end surface is to narrow end surface.Can avoid causing additional axial force like this, and can axle or shell are limited in the end-play scope at both direction.
Adopt the motor of the angular contact ball bearing of mounted in pairs, can bear bi-directional axial power, realized goal of the invention of the present utility model.
Claims (2)
1. threephase asynchronous that can bear bi-directional axial power, comprise motor casing (1), rotor, stator, terminal box, End cover for motor (4), main shaft (2) and bearing (9) thereof, described bearing (9) are installed between main shaft (2) and the End cover for motor (4); It is characterized in that: the external screw thread that described main shaft (2) is provided with stop film trap (8) and mates with retainer nut (7); Described bearing (9) is sleeved on after main shaft (2) goes up, and locking plate (6) is installed in the stop film trap (8) of main shaft (2), on main shaft (2) and external screw thread retainer nut (7) coupling retainer nut (7) is installed, and bearing outer end cap (5) is installed at last.
