Abstract
The invention relates to a braking part for motor, which is used for motor braking; the braking part comprises a shell (1), an air gap measuring table (2), a releasing screw (3), a friction plate (4), an end cover (6), a braking part (6), an armature (7), a compression spring (8) and an excitation winding (9); the braking part is characterized in that: the friction plate (4) is replaced by a friction block, and the friction block is directly placed in a braking disk, and the braking parties connected with the rotating shaft of the motor by a bond; when the excitation winding (9) is powered on, an iron core attracts the armature (7), the motor is released; when the excitation winding is powered off, the compression spring pushes the armature to push against the end cover by the friction block, so as to lead the rotating part not to rotate and lead the motor to brake. The braking part, the friction block of the braking part and the rotating shaft of the motor have no relative movement and the friction block does axial movement in the braking disk within a working air gap range, so as to lead the motor to release or brake.
Description
Technical field
The present invention relates in brake, replace friction plate with brake pad, improving brake component useful life, and simple in structure, transposing is convenient, belongs to technical field of motors.
Background technology
In electromotor brake, after the outage of the magnetizing coil in the brake, the compression spring promptly promotes armature, makes brake component withstand electric motor end cap, and brake component promptly can not rotate, thereby makes motor braking.
At present, motor braking spare all is to be formed on brake disc with rivet by friction plate, and brake component connects with motor shaft with spline, and brake component can be in axial sliding on axle.
Observe by research, this motor braking spare exists following several problem:
1, contact when braking with electric motor end cap when the brake component friction plate, the time of a stall arranged, this moment friction plate with end cap between a relative motion is arranged, motor speed by at a high speed until static.In time, friction plate just has wearing and tearing at this stall.And the friction plate outer peripheral portion since stall in the time relative velocity bigger, wearing and tearing are inevitable severe.Time one is long, make the friction plate outer peripheral portion when braking, contact with electric motor end cap defective tightness, this causes the braking radius of brake to reduce, braking moment diminishes, and has prolonged the braking time of brake, and makes the easier wearing and tearing of friction plate.
2, with the brake component complex structure of friction plate, make difficulty.
3, (working clearance of brake is generally 0.6～2.0mm), must change friction plate, and is because the structure of brake component is complicated, cumbersome when therefore changing after to a certain degree when friction disc wear.If replace friction plate with brake pad, the problems referred to above all can solve.
Summary of the invention
The purpose of this patent is to provide a kind of brake pad to replace friction plate in the electromotor brake, thus the useful life of improving brake component in the brake, and simple in structure, make convenient easy to use.
For achieving the above object, technical scheme of the present invention is: adopt brake pad in brake component, brake pad is provided with in the hole of brake component, be provided with certain clearance between brake pad and brake disc, brake pad can be rotated in brake disc, and when stall, the degree of wear of brake pad all is identical.Secondly, simple in structure with the brake component of brake pad, the transposing of wearing and tearing back is also very convenient, as long as open electric motor end cap, takes off the brake pad of wearing and tearing, changes new brake pad and gets final product.
Beneficial effect of the present invention: adopt this structure of the present invention because brake pad can rotate in brake disc, therefore wearing and tearing evenly, the life-span that can improve brake component, and simple in structure, change very conveniently, have the certain economic effect.
Below in conjunction with drawings and Examples to the technical scheme of the present invention detailed explanation of making comparisons.
Description of drawings
Fig. 1. for using the structure chart of the brake component of friction plate in the present brake;
Fig. 2. what use for brake is the brake pad structure chart;
Fig. 3. be the structure chart of the brake component of use brake pad of the present invention.
Embodiment
With reference to Fig. 1, this is the structure chart that uses the brake component of friction plate in the brake of prior art.
As shown in the figure, wherein rivet 1, friction plate 2, brake disc 3, two friction plates before and after its structure is served as reasons form on brake disc with rivet,
Brake component uses splined on motor shaft.Brake component can move axially in the air gap working range on the axle of motor with spline, motor is discharged or braking.The front is stated, friction plate in radius major part since when braking relative velocity big and wearing and tearing easily reduce the brake braking force square, its complex structure secondly, brake(-holder) block wearing and tearing back transposing is trouble very.
With reference to Fig. 2, what this was that brake uses is the brake pad structure chart.
Its structure as shown in the figure, wherein shell 1, measurement of air gap platform 2, release screw 3, brake pad 4, end cap 5, brake component 6, armature 7, compression spring 8, magnetizing coil 9, iron core 10.
After the magnetizing coil energising, the iron core adhesive armature discharges motor.After the magnetizing coil outage, the compression spring promotes armature, makes brake pad withstand end cap, brake component can not be rotated, thereby make motor braking.
With reference to Fig. 3, this is the structure chart of the brake component of use brake pad of the present invention.
Its structure as shown in the figure, wherein brake disc 1, brake pad 2, brake pad is as long as directly puts into brake disc.Brake component connects with machine shaft with key.Therefore during brake work, brake component and machine shaft do not have relative motion, but brake pad in brake disc in the working gas gap scope, move axially, motor discharged or brake.The front is stated, and therefore this structure weares and teares evenly because brake pad can rotate in brake disc, the life-span that can improve brake component, and simple in structure, change very convenient.
Though the present invention describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the present invention; should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense; so be not as limitation of the invention; as long as in connotation scope of the present invention, to the variation of above-described embodiment, the protection range that distortion all will fall into claim of the present invention.
