Abstract
The utility model discloses a kind of grass-mowing machine motors, the grass-mowing machine motor includes shell and motor, and the motor is equipped with shaft, and the both ends of the shaft is all located at outside motor, the motor is mounted in shell, is flexibly connected between the shell and shaft by ball.By the way that ball is arranged in shaft one end inside grass-mowing machine motor, play the role of that shaft and shell is inhibited to collide, reduce the friction that shell is subject to, so that the stability of entire motor work improves, the service life of motor extends.
Description
Technical field
The utility model relates to the connections of the shaft and shell of a kind of grass-mowing machine motor more particularly to motor motor internal
Structure.
Background technique
The power of electric grass mowing equipment generallys use the structure that shell adds motor from motor, this motor, and motor is fixed
In shell, damage that this structure lower case can be effectively protected motor, avoid external factor.But this structure exists
Fault of construction, when use, which will appear, to collide and rubs between shell and the shaft of motor, causes the damage of housing interior structure
Wound, this can adversely affect entire motor, shorten the service life of grass-mowing machine.The shaft of motor can be along shaft centerline
Side translate up a distance, but translational movement is very small, and the motion feature be not in the original design of shaft both
Determine function, shaft translation will cause motor internal bearings and bear very big external force, easily motor be caused to damage.
Summary of the invention
The technical problems to be solved in the utility model is the translational motion for how inhibiting shaft to do along its centerline direction,
Thus obtain that a kind of structure is simple, grass-mowing machine motor with long service life.
In order to solve the above technical problems, the utility model adopts the following technical solution: the grass-mowing machine motor includes shell
And motor, the motor are equipped with shaft, the both ends of the shaft is all located at outside motor, and the motor is mounted in shell, institute
It states and is equipped with installation protrusion in shell, the extending direction of the installation protrusion is overlapped with the center line of shaft, in the installation protrusion
Equipped with joint face, the joint face is plane, and for the central axis of the shaft in joint face, the shaft is equipped with groove,
The groove be equipped with cross section in cone position, the groove direction is overlapped with the center line of shaft, the shell and
It is flexibly connected between shaft by ball, the ball is embedded in groove, and the ball is clamped in installation protrusion and shaft
Between.
Ball is set in one end of shaft, ball two sides are directly connect with shell and shaft, and shaft is inhibited to do along wherein
The translational motion in heart line direction, to make to avoid collision between shaft and shell.The connection of installation protrusion on ball and shell
Face is connected in a manner of point contact, this can greatly reduce the rubbing action that shell is subject to.Relative position based on shaft and shell
Changeless structure bearing inside effective protection motor and can improve the stability of entire motor work, extend electricity
The service life of machine.
Groove is greater than the diameter of ball in cross section in the width of the opening at the position of cone, on the one hand may insure to roll
The case where pearl is embedded in groove always, ball is avoided to be detached from groove, is on the other hand convenient for assembly operation.
By increasing shaft to the package degree of ball, the conjugation of ball and shaft, conjugation promotion pair can be promoted
In avoid ball be detached from groove the case where advantageously, as long as ball be located at installation protrusion and shaft between, even if between three
Gap is generated, still may insure that ball plays the effect avoided collision, this has important meaning for extending motor service life
Justice.For this purpose, the groove is additionally provided with the position that cross section is in rectangle, the cross section of the groove is in the center at the position of cone
Line is overlapped with the cross section of groove in the center line at the position of rectangle, and the cross section of the groove is in the maximum at the position of cone
Width be equal to groove cross section in rectangle position width.
The utility model is by adopting the above technical scheme: by the way that ball is arranged in shaft one end inside grass-mowing machine motor, rising
To inhibiting shaft and shell to collide, reduces the effect of the friction that shell is subject to, so that the stability that entire motor works
It improves, the service life of motor extends.
Detailed description of the invention
The utility model is further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural schematic diagram of grass-mowing machine motor of the utility model.
Specific embodiment
As shown in Figure 1, grass-mowing machine motor includes shell 1 and motor 2.Motor 2 is mounted in shell 1, and motor 2 is equipped with
Shaft 3,3 both ends of shaft are all located at outside motor 2 and one end of shaft 3 is located inside shell 1, the other end conduct of shaft 3
The power output end of entire grass-mowing machine motor is located at outside shell 1.Installation protrusion 4 is equipped in shell 1, installation protrusion 4 is prolonged
It stretches direction to be overlapped with the center line of shaft 3, installation protrusion 4 is equipped with joint face, and joint face is plane, and the center line of shaft 3 hangs down
Directly in joint face.Shaft 3 is equipped with groove 6, and groove 6 includes two parts, one be cross section in cone position, another
A is the position that cross section is in rectangle, and the cross section of groove 6 is in square in the center line at position and the cross section of groove 6 of cone
The center line at the position of shape is overlapped, and the cross section of groove 6 is in the cross section that the maximum width at the position of cone is equal to groove 6
The width at the position of rectangle.The direction of groove 6 is that the center line of groove 6 is overlapped with the center line of shaft 3, shell 1 and shaft 3 it
Between be flexibly connected by ball 5,5 side of ball is embedded in groove 6, the other side and joint face are located next to, and ball 5 is clamped in
Between installation protrusion 4 and shaft 3.Since groove 6 is greater than the straight of ball 5 in the width of the opening at the position of cone in cross section
Diameter, so the cross section of groove 6 is wrapped in 5 surrounding of ball in the position of rectangle.Shaft 3 is connect by ball 5 with shell 1, is pressed down
It has made shaft 3 and has done translational motion along its centerline direction, to make to avoid collision between shaft 3 and shell 1.Ball 5 with
The joint face of installation protrusion 4 on shell 1 is connected in a manner of point contact, this can greatly reduce the rubbing action that shell 1 is subject to.
