Abstract
The utility model relates to a novel gate mechanism, in particular to a gate mechanism which is provided with a fan cooling device and prevents a worm shaft from moving along the axial direction. The gate mechanism is characterized in that a fan groove and a screw hole are designed at the lateral surface of a speed reducer; and a fan is arranged in the fan groove. The fan cooling device lowers the temperature of a motor, so that the motor can well adapt to frequent start; a steel ball and a bolt are arranged in the screw hole at the middle-lower part of the speed reducer; the steel ball is in contact with a central hole at the bottom of the worm of the worm shaft, so as to prevent the worm shaft from moving along the axial direction.
Description
Technical field
The utility model relates to a kind of banister movement, relates to a kind of novel banister movement that has fan cooled and prevent worm shaft axial motion device specifically.
Technical background
1. existing banister core motor starts frequent, and caloric value is big, and does not have cooling device, and heat protection easily quits work motor.
2. the worm shaft of existing banister movement axially has the gap, and during work, axial motion can appear in worm shaft.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel banister movement, bans original banister movement, can reduce the temperature rise of motor and prevent the worm shaft axial motion, and structure is novel, and is simple and reasonable for structure.
Technical problem of the present invention realizes by following technical scheme: construct a kind of novel banister movement, comprise motor, reduction box, cooling device.
According to a kind of novel banister movement provided by the invention, it is characterized in that motor comprises motor casing, rotor, bearing, worm shaft.Rotor is fixed on worm shaft top, and a plurality of holes that are used to ventilate are arranged on the rotor.The upper end of worm shaft cooperates with motor casing by bearing, and the lower end cooperates with the top of deceleration box by bearing.The top of motor casing has a plurality of holes that are used to ventilate.Motor casing is fixed on the top of deceleration box.
According to a kind of novel banister movement provided by the invention, it is characterized in that reduction box comprises cooperation, the other end cooperates with end cap 207 by bearing 205.End cap 206 and end cap 207 are separately fixed at two of deceleration box 201.Steel ball 208 is installed in the screwed hole 211 of deceleration box 201, and the centre bore with the end of worm shaft 15 contacts, and the other end contacts with screw 209.Locking nut 210 is fixed on the screw 209.Adjust screw 209, can eliminate the end play of worm shaft 15, promptly eliminated the axial motion of worm shaft 15.
Description of drawings
Fig. 1 is banister cassette mechanism structure figure of the present utility model;
Fig. 2 is a banister movement cutaway view of the present utility model;
Fig. 3 is a banister movement cooling device structure chart of the present utility model;
Fig. 4 is banister movement gap adjusting structure figure of the present utility model.
Specific embodiment
Below in conjunction with specific embodiment, be further elaborated.
As shown in Figure 1 and Figure 2, novel banister core device of the present invention comprises motor 1, reduction box 2, cooling device 3.
In 201 the fan groove 33, fan guard 32 is fixed on the last plane of fan groove 33.Shown in figure three, fan groove 33 inside communicate with the top of deceleration box 201, so, when fan 31 rotated, cooling air flowed into from the top of motor casing 11, by the ventilation hole of rotor 12, flow out from fan groove 33, take away most of heat that motor 1 sends, reduce the temperature rise of motor 1, play cooling effect.
The utility model banister core device has overcome the shortcoming of traditional banister movement, and air cooling equipment has reduced the temperature rise of motor, makes motor more adapt to frequent operation.Eliminated the axial motion of worm shaft.And it is succinct, attractive in appearance.More can satisfy client's demand.
