Abstract
The utility model belongs to the motor field, in particular to compact lead screw motor that transmission precision is high. Compact lead screw motor, it includes the stator, is provided with the rotor in the stator, is provided with in the rotor to lead to the axle, the both ends of stator are provided with front end housing and rear end cap, its characterized in that respectively: the both ends that lead to the axle all be equipped with and be provided with the tensioning spring along with leading to an axle pivoted nut, leading to between axle and the nut, screw connection is on the nut. The utility model discloses compact structure, the transmission precision of lead screw motor has been improved in the clearance of effectively eliminating the lead screw drive in -process.
Description
Technical field
The utility model belongs to machine field, the compact spindle motor that particularly a kind of transmission accuracy is high.
Background technology
Through spindle motor of the prior art, leading screw with the axis of motor in move up and down, owing to there is a gap between the screw thread on leading screw and the screw thread on axis, when motor rotates backward, leading screw needs first to run one end to offset the gap between threads of lead screw and axis screw thread, has influence on the transmission accuracy of whole system.
Summary of the invention
For above-mentioned technical problem, the utility model compact conformation, effectively eliminates the gap in lead screw transmission process, improves the transmission accuracy of spindle motor.
Realize the technical solution of the utility model as follows:
Compact spindle motor, it comprises stator, rotor is provided with in stator, axis is provided with in rotor, the two ends of stator are respectively arranged with front end housing and rear end cap, it is characterized in that: the two ends of described axis are equipped with the nut along with axis rotates, and be provided with tensioning spring between axis and nut, leading screw is connected on nut.
The end of described axis is provided with groove, and the surface of described nut is provided with locating piece, locating piece and groove fit, and the utility model is coordinated by locating piece and groove, when axis rotates, drives the rotation of nut.
Be provided with the bearing supported axis in described front end housing and rear end cap, the bearing of setting can support axis, improves axis traveling comfort, is then conducive to the transmission accuracy improving motor.
In sum, the utility model has following beneficial effect:
The utility model effectively eliminates gap between leading screw and nut to the impact of spindle motor transmission accuracy, improves the transmission accuracy of spindle motor, and not, the utility model structure is simple, can not increase the production cost of motor, be conducive to the popularization of motor simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be A-A of the present utility model to cutaway view;
Fig. 3 is the assembling schematic diagram of axis and nut;
Fig. 4 is the schematic diagram that nut thread coordinates with threads of lead screw;
In figure, 1 is front end housing, and 2 is nut, and 3 is leading screw, and 4 is stator, and 5 is rotor, and 6 is rear end cap, and 7 is bearing, and 8 is tensioning spring, and 9 is axis, and 91 is groove, and 21 is locating piece.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Compact spindle motor as shown in Figures 1 to 4, it comprises stator 4, rotor 5 is provided with in stator 4, axis 9 is provided with in rotor 5, the two ends of stator 4 are respectively arranged with front end housing 1 and rear end cap 6, the two ends of described axis 9 are equipped with the nut 2 along with axis rotates, tensioning spring 8 is provided with between axis 9 and nut 1, 3 leading screws are connected on nut, the tensioning spring arranged has an outside thrust, fitted with a side of the screw thread of leading screw all the time in one side of the screw thread of nut, then when motor rotates forward or reverses, gap is there is not between leading screw and nut, namely there is not driving error, improve the transmission accuracy of spindle motor.
The end of described axis 9 is provided with groove 91, and the surface of described nut 2 is provided with locating piece 21, and locating piece 21 coordinates with groove 91, and the utility model is coordinated by locating piece and groove, when axis rotates, drives the rotation of nut.
Be provided with the bearing 7 supported axis in described front end housing 1 and rear end cap 6, the bearing 7 of setting can support axis, improves axis traveling comfort, is then conducive to the transmission accuracy improving motor.
In sum, the utility model has following beneficial effect:
