Abstract
The utility model discloses a disc brake applied on a motor shaft, comprising a basal body fixed on a motor casing and a cover body connected with the basal body. A friction disc between the basal body and the cover body is fixed on the motor shaft; a wearing layer is respectively arranged at the side of the basal body and the cover body; a plurality of springs are evenly arranged around the motor shaft in the cover body, and prop against the wearing layer; and an energized magnetic field is also arranged on the cover. The disc brake applied on the motor shaft has the advantages that: with excellent braking effects, the size is relatively small, thus leading to more compact structure of the brake; simultaneously, due to the use of smaller radius, the moment of inertia is accordingly reduced, thus realizing quicker braking and saving the consumables.
Description
Technical field
The utility model relates to a kind of disk type braker that is applied on the motor shaft.
Background technique
Motor commonly used generally is not provided with brake structure, still is in operation for those and can often carries out arrestment as required, and the frequent power on/off of needs is controlled the motor operation or stopped.And generally be not easy to reduce to zero at once for the rotating speed of motor that runs up, and so a kind of braking device of employed design of electrical motor is given in the workplace of using such motor at needs, use that can more convenient user.
The multiple mode of braking of present domestic employing, but structure and characteristics respectively have quality, as application number is the Chinese patent that 02160856.3 disclosed name is called disk type braker and torque transmitter, can well play the effect of braking, but owing to adopt the mode of electric machine casing being carried out friction catch, so the radius of braking device is generally bigger, and then rotary inertia also increases the also increase of friction infringement that so each braking brought thereupon.
The utility model has been installed a kind of small size, the less relatively disc brake assembly of rotary inertia by my design on motor shaft, can play good braking effect, and the friction infringement is also less.
The model utility content
The purpose of this utility model provides a kind of disk type braker that is applied on the motor shaft, adopts simple and compact structure to reach the effect of braking.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of disk type braker that is applied on the motor shaft, comprise the matrix that is fixed on the electric machine casing and with matrix by bolted lid, on motor shaft, be fixed with friction plate, described friction plate is between matrix and lid, the side of matrix and lid is equipped with wearing layer, inside at lid evenly is provided with some springs around motor shaft, and described spring withstands on the wearing layer, also is provided with energising magnetic field on lid.
The beneficial effects of the utility model are: braking effect is good, but volume is less relatively, can make the structure of break compact more; Simultaneously, owing to adopt less integral radius, rotary inertia decreases, and brake faster rapidly, and can reach the purpose that reduces consumptive material.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the described disk type braker structural drawing that is applied on the motor shaft of the utility model embodiment.
Among the figure:
1, electric machine casing; 2, matrix; 3, lid; 4, friction plate; 5, wearing layer; 6, energising magnetic field; 7, spring; 8, motor shaft.
Embodiment
As shown in Figure 1, omitted the stator of motor among the figure, other parts of rotor portion and main shaft and body, the disk type braker that is applied on the motor shaft described in the utility model, comprise the matrix 2 that is fixed on the electric machine casing 1 and with matrix 2 by bolted lid 3, on motor shaft 8, be fixed with friction plate 4, described friction plate 4 is between matrix 2 and lid 3, the side of matrix 2 and lid 3 is equipped with wearing layer 5, inside at lid 3 evenly is provided with some springs 7 around motor shaft 8, described spring 7 withstands on the wearing layer 5, also is provided with energising magnetic field 6 on lid 3.
In the process of motor operation, give magnetic field 6 energisings, magnetic field 6 produces magnetic attraction wearing layer 5, and wearing layer 5 just can not contact with friction plate 4; When motor stopped operating, energising magnetic field 6 also cut off the power supply, and the magnetic force in magnetic field 6 disappears, and 7 pairs of wearing layers of spring this moment 5 produce the elastic force effect and push wearing layer 5 to friction plate 4, thereby wearing layer 5 closely contacts the purpose that reaches braking with friction plate 4.
Disk brake described in the utility model is compared with other brake, and braking effect is good, still The volume less can make the structure of brake compacter; Simultaneously, owing to adopt littler integral body half Directly, rotary inertia decreases, brake faster rapidly, and can reach the purpose that reduces consumptive material.
Claims (2)
1, a kind of disk type braker that is applied on the motor shaft, comprise matrix that is fixed on the electric machine casing and the lid that is connected with matrix, it is characterized in that: on motor shaft, be fixed with friction plate, described friction plate is between matrix and lid, the side of matrix and lid is equipped with wearing layer, inside at lid evenly is provided with some springs around motor shaft, and described spring withstands on the wearing layer, also is provided with energising magnetic field on lid.
2, disk type braker according to claim 1 is characterized in that, described matrix is connected by bolt with lid.
