Abstract

The utility model relates to a linear electric motor with a simple installation process, which comprises a secondary pole and primary pole sheathed outside the secondary pole. The utility model is characterized in that a plurality of windings of a winding group and iron cores matched with the windings are stacked between two support seats, the windings, the iron cores and the support seats are sheathed outside the same inner sleeve, and the outer sides of the support seats are impacted by both ends of the inner sleeve. When users install the utility model, the windings, the iron cores and the support seats are sheathed outside the inner sleeve firstly, and both of the two ends of the inner sleeve are everted to impact the outer sides of the support seats, so each component turns into a machine core; then, the machine core can be conveniently put into an outer casing, and installation process is simplified.

Technical field

The utility model relates to a kind of motor, particularly a kind of linear electric motors.

Background technology

In November 28 calendar year 2001 disclosed Chinese patent bulletin CN2461436Y, a kind of " the quiet curtain of linear electric motors remote control " disclosed, it is made up of linear electric motors, Curtain rod and curtain, wherein the elementary of linear electric motors is enclosed within outside the secondary composite metal bar that is fixed on window two end supports, adorn bearing or rolling member between the two, be provided with elementary iron core, primary coil group and shell in elementary, be secondary iron core in the secondary composite metal bar, be secondary conductor outward, the tieback that casement is housed hangs on the secondary composite metal bar; When wherein linear electric motors are installed, be after earlier coil groups wiring and lead-in wire being connected, coil and iron core put into one by one shell again, its shortcoming is the mounting process complexity, and production efficiency is low, and installation process is damaged coil lead easily.

Summary of the invention

The purpose of this utility model is the low problem of mounting process complexity, production efficiency that exists in the existing linear electric motors in order to solve, and the linear electric motors that a kind of mounting process is simple, production efficiency is high are provided.

Technical scheme:

The purpose of this utility model is achieved in that a kind of linear electric motors, comprise secondary and be enclosed within secondary outer elementary, wherein elementaryly form by coil groups, iron core, shell, and secondary be that outer surface is the strip magnetic conductor of electric conductor, it is characterized in that the some coils and the supporting iron core that constitute coil groups overlay between two bearings spaced reciprocally, each coil, iron core and bearing are enclosed within outside the same interior cover, turn up and compress the bearing outside in interior cover two ends.During installation, outside the cover, in making turn up to compress the bearing outside in the cover two ends again, makes each parts become movement, can easily movement be put in the shell then, simplified mounting process in only needing earlier each coil, iron core and bearing to be enclosed within.

Described linear electric motors is characterized in that described two bearings outside is respectively equipped with the end cap of clamping the shell two ends, fix with screw between end cap and the corresponding bearing.Shell is a tubulose, clamps and fixes with movement by two end cap.

Described linear electric motors is characterized in that described end cap is provided with radiation-like and is distributed in the groove more than three or three that end cap is inboard and communicate with the end cap axis hole, are equipped with a roller in every groove, with reduce elementary and secondary between frictional force during relative motion.

Described linear electric motors, the outside that it is characterized in that at least one end cap is provided with leads the curtain arm, and this is led on the curtain arm and has hanging hole.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, when linear electric motors are installed, outside the cover, in making turn up to compress the bearing outside in the cover two ends again, makes each parts become movement in only needing earlier each coil, iron core and bearing to be enclosed within, can easily each winding wiring and lead-in wire be connected then, integral body is put in the shell afterwards, has simplified mounting process, has improved production efficiency, and, reduced the chance that coil lead is damaged in installation process; The roller that three radiation-like distribute is set on the end cap, has reduced the frictional force between elementary and secondary.

Embodiment:

Fig. 1 be linear electric motors described in the utility model be used for electrically driven curtain the time the internal structure schematic diagram.In conjunction with each accompanying drawing as seen, described linear electric motors, comprise secondary 5 and be enclosed within secondary 5 outer elementary, wherein elementary iron core 3, tube-like envelope 1 by coil groups 2, annular formed, coil groups 2 and iron core 3 overlay between two

bearings

61,62 spaced reciprocally, outside the cover 4, interior cover was translated into the outside that flange 401,402 compresses bearing 61,62 outside 4 two ends in coil groups 2, iron core 3 and bearing 61,62 were enclosed within.Shell 1 inwall is provided with axial location muscle 101, has the breach 622 (Fig. 3) that matches with positioning bar 101 on the
