Abstract
The utility model relates to a lead screw support structure of improvement type, including lead screw, bearing, the bearing be at least two, it is solid on the lead screw to arrange the cover in proper order. The utility model discloses an atress at motor lead screw support structure position is even, and quality of a motor is high.
Description
Technical field
This utility model is related to Motor drive field, especially relevant with a kind of screw mandrel supporting structure of modified form.
Background technology
At present more and more extensively, after Motor drive output, conventional is by circumference by feed screw nut for the application of small machine
Motion is converted into linear motion.General screw mandrel is all that one bearing of set is supported on housing, and at present existing screw structure, adopts
Supporting is gone with single bearing, such screw mandrel lifting surface area is little, and degree of stability is not high, therefore the present inventor designs a kind of modified form
Thus screw mandrel supporting structure, this case produces.
Utility model content
The purpose of this utility model is to provide a kind of screw mandrel supporting structure of modified form, it is ensured that uniform force, motor quality
It is high.
For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of screw mandrel supporting structure of modified form, including screw mandrel, bearing, described bearing is at least two, is arranged in order
It is fixed on screw mandrel.
Described screw mandrel is bearing in electric motor end cap by bearing.
The jut for accommodating bearing is outwardly formed on described electric motor end cap.
The height of described jut is the thickness sum of two bearings.
It is of the present utility model to have the advantages that compared with existing turning device：
1st, it is main by using duplex bearing supported in this utility model, than the stress surface that original single-bearing increased a times
Product so that the degree of support of screw mandrel is more stable.
2nd, duplex bearing is adopted in this utility model, in use one of bearing damage also has another to continue
Work, while also only needing to change one of bearing, maintenance cost is low, high working efficiency.
3rd, scalability design has also accordingly been done in electric motor end cap cooperation in this utility model, assembles between the screw mandrel for being and end cap
Small volume, reliability is high.
Description of the drawings
Fig. 1 is the generalized section of this utility model preferred embodiment.
Specific embodiment
Referring to Fig. 1, this utility model preferred embodiment is further elaborated.
A kind of screw mandrel supporting structure of modified form, the part being mainly concerned with has screw mandrel 1, bearing 2, the present embodiment middle (center) bearing
2 have 2 two, are arranged in order and are enclosed within screw mandrel 1.After 1 set of upper bearing (metal) 2 of screw mandrel, through electric motor end cap 3 supporting and fixing is carried out.
In the present embodiment in order to more preferably coordinate screw mandrel 1, outwardly convex forms a jut 4, jut to electric motor end cap 3
4 height is substantially equal with the height sum of two bearings 2, therefore can just coordinate receiving to install two tandems together
Bearing 2.
Screw mandrel 1 is bearing on electric motor end cap 3 during utility model works, two collective effects of bearing 2, is provided to screw mandrel 1
Dual stress, one of damage is unaffected, while screw mandrel 1 is big one times with the forced contact area of bearing 2, work
Make more stable reliability.
More than one kind of this utility model preferred implementation, make under this utility model concept thereof it is some its
He is simple to replace and changes, and should all be considered as belonging to protection category of the present utility model.
