Description
Technical field
The utility model relates to a kind of miniature power-off brake, is specifically related to a kind of geared sleeve of miniature power-off brake.
Background technique
HDWZ1 series mini power-off brake is energising release, and the frictin braek of spring to break braking, can be supporting with micro motor.Be widely used in the automation mechanical driving systems such as a machine driving, electric wheelchair, storage control for brake, stage and theater machinery, automatic door, medical apparatus, stepper motor, move quick parking, the effects such as safety brake.It is simple that this type of break has compact structure, and easy for installation, noise is low, brakes the features such as steady, and having braking maintenance two kinds of functions, is a kind of idealized executive component.
The geared sleeve of conventional power-off brake is in the process of installing, need first on the bearing of motor, a check ring inner ring to be installed, install geared sleeve again, geared sleeve installs a check ring outer ring after installing again, check ring needs the two ends successively check ring being arranged on geared sleeve with pliers when installing and using, the installation process time is longer, and prior art can not realize the installation of geared sleeve check ring fast, affects pilot break installation efficiency.
Model utility content
For above problems of the prior art, the utility model provides a kind of geared sleeve being different from conventional power-off brake.
The utility model is achieved through the following technical solutions:
The geared sleeve of miniature power-off brake, comprise bearing of motor, motor fan cover, geared sleeve and check ring, described geared sleeve is installed on the motor fan cover side of bearing of motor, it is characterized in that: described geared sleeve both ends of the surface are provided with arc groove, described arc groove is respectively arc groove and outer arcuate groove, the side of close motor fan cover is arc groove, inner spring back-up ring is provided with in described arc groove, outer spring back-up ring is provided with in described outer arcuate groove, two through circular holes are provided with between described two arc grooves, described circular hole is provided with two flat keys near inner spring back-up ring, the left side of described flat key is provided with spring, button is provided with on the left of described spring, described button is connected with thumb-button push rod.
Described Circularhole diameter is greater than the width of outer spring back-up ring.
Described its length is greater than the length of arc groove to geared sleeve exterior edge face.
Described spring diameter is greater than the distance in two flat key gaps, and described spring is less than Circularhole diameter.
The beneficial effects of the utility model are: by being provided with the button of arc groove and promotion arc groove inner spring back-up ring on geared sleeve, geared sleeve is directly shifted onto the corresponding position of bearing of motor in installation process, press the restraining groove that two button inner spring ejecting cards are incorporated into formulation, prevent geared sleeve without axial motion, outer spring back-up ring is taken out in outer ring groove, this practicality is installed faster, can reduce the time that power-off brake is installed, and improves the efficiency that power-off brake is installed.
