Abstract
The utility model discloses a motor bearing locking structure, which includes a rotating shaft (1) and a bearing (2), wherein a locking cover (4) is arranged at the end part of the rotating shaft (1); the end surface (41) of the locking cover (4) is propped against the outer end surface (21) of an inner ring of the bearing (2); the rotating shaft (1) is fixedly connected with a locking bolt (3) in the axial direction; the rod body of the locking bolt (3) penetrates the locking cover (4) and then is matched with the rotating shaft (1); a locking piece (5) is arranged between the head part of the locking bolt (3) and the locking cover (4); and the edge of the locking piece (5) is outwards folded and clamps the head part of the locking bolt (3). According to the utility model, the bearing is locked by the locking cover, and the contact surface between the locking cover and the bearing can be well controlled, so that the service life of the bearing can be prolonged; and on the other hand, no damage is caused to the bearing when the locking piece is hammered during the assembly or disassembly process.
Description
Technical field
The utility model relates to a kind of locking mechanism, particularly relates to a kind of structure that is used for the locking motor bearing.
Background technique
In the existing technology, bearing is locked through locking nut and lock washer, and threading in rotating shaft is screwed in locking nut in the rotating shaft, lock washer is clenched block locking nut again, prevents that locking nut is loosening in the rotating shaft rotation process.The shortcoming of this structure is: through screw-threaded coupling, so lock washer can not contact with contact plane between the bearing fully, causes shaft strength uneven, damages bearing easily; On the other hand, need beat lock washer when assembling or dismounting,, be easy to strike bearing bad because lock washer contacts with bearing.
Therefore those skilled in the art are devoted to develop and a kind ofly can effectively lock bearing, and can avoid bearing to suffer the motor bearings locking mechanism of extra infringement.
The model utility content
Because the above-mentioned defective of existing technology, the utility model technical problem to be solved provides a kind ofly can effectively lock bearing, and can avoid bearing to suffer the motor bearings locking mechanism of extra infringement.
For realizing above-mentioned purpose, the utility model provides a kind of motor bearings locking mechanism, comprises rotating shaft and bearing; The end of said rotating shaft is provided with tightening cover; The end face of said tightening cover props up the exterior edge face of said bearing inner race; Said rotating shaft is fixedly connected with lock bolt vertically; The shaft of said lock bolt cooperates with said rotating shaft after passing said tightening cover; Be provided with lock sheet between the head of said lock bolt and the said tightening cover; The edge of said lock sheet turns up and blocks the head of said lock bolt.
Preferable, said lock bolt is circle distribution in the end of said rotating shaft.
Preferable, the end of said rotating shaft is provided with six said lock bolts.
The beneficial effect of the utility model is: the utility model is through tightening cover locking bearing, and contacting meet between tightening cover and the bearing can be controlled finely, thereby improves bearing life; On the other hand, beaing lock sheet in assembling or the unloading process can not damage bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the partial enlarged drawing at I place among Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of motor bearings locking mechanism comprises rotating shaft 1 and bearing 2.The end of rotating shaft 1 is provided with tightening cover 4, and the end face 41 of tightening cover 4 props up the exterior edge face 21 of bearing 2 inner rings.
Rotating shaft 1 is fixedly connected with lock bolt 3 vertically, and the shaft of lock bolt 3 passes tightening cover 4 back and cooperates with rotating shaft 1, is provided with lock sheet 5 between the head of lock bolt 3 and the tightening cover 4, and the edge of lock sheet 5 turns up and blocks the head of lock bolt 3.
In the present embodiment, the end of rotating shaft 1 is circle distribution has three lock bolts.
In other embodiments, the lock bolt of other quantity also can be set, as 4,6,8,9 etc., to reach essentially identical technique effect.
In other embodiments, lock bolt also can be the end of other distribution of shapes in rotating shaft, like rectangle, regular hexagon etc., to reach essentially identical technique effect.At this moment, the shape of lock washer is made corresponding change and is got final product.
Claims (3)
1. a motor bearings locking mechanism comprises rotating shaft (1) and bearing (2); It is characterized in that: the end of said rotating shaft (1) is provided with tightening cover (4); The end face (41) of said tightening cover (4) props up the exterior edge face (21) of said bearing (2) inner ring; Said rotating shaft (1) is fixedly connected with lock bolt (3) vertically; The shaft of said lock bolt (3) passes said tightening cover (4) back and cooperates with said rotating shaft (1); Be provided with lock sheet (5) between the head of said lock bolt (3) and the said tightening cover (4); The edge of said lock sheet (5) turns up and blocks the head of said lock bolt (3).
