Abstract
The utility model discloses a motor damping brake device which is arranged on a tail shaft of a motor, and comprises a fixed block (1) and a rubber ring (2), wherein the fixed block (1) is internally provided with a cylindrical hole (3), and the rubber ring (2) is fixed in the cylindrical hole (3); the interior of the fixed block (1) is made to be hollow, and the fixed block (1) is provided with a screw hole (4) and is internally filled with lubricating oil through the screw hole (4); a screw is adopted for sealing the screw hole; and the rubber ring (2) is communicated with the interior of the fixed block (1). When the motor is turned off, a motor shaft continuously rotates due to action of inertia; while under the action of the damping device, the motor can difficultly drive a speed reducer by virtue of inertia, thus playing a role of effective braking to the motor finally. Compared with the electromagnetic brake, the motor damping brake device has the advantages of simple structure, convenient maintenance and low cost.
Description
Technical field
The utility model relates to machine field, is a kind of motor damping brake apparatus specifically.
Background technology
The common connection reducer of the motor of prior art uses together, and the output shaft of decelerator drives other mechanism again, and decelerator inside is reducing gear, as worm-and-wheel gear.One end of the output shaft of motor is in order to connect decelerator to drive load, and the other end then dallies, and this end often is wrapped in the shell of motor, generally is referred to as tailing axle.
Yet in disable motor, motor can be rotated further owing to certain inertia, this inertia may drive decelerator works on a bit of time load, a lot of this inertia of occasion are harmful to, as are installed in the motor in the lowering or hoisting gear, if untimely braking then can exceed stroke.The braking of present motor generally adopts electromagnetism to stop, electromagnetism stop motor close the back energising can nip the effect that machine shaft plays braking, need energising and adopt electromagnetism to stop, and because the complicated general personnel that use of its structure are difficult to maintenance, cost is also higher relatively.In addition in motor-driven lowering or hoisting gear, in uphill process, disable motor or sudden power, on the goods carried too heavily overload because the action of gravity meeting descends and makes the motor counter-rotating.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of simple in structure, convenient for maintaining, cost low, can also prevent the motor damping brake apparatus of motor counter-rotating.
Technical solution of the present utility model is, a kind of motor damping brake apparatus of following structure is provided, and described damping device is installed on the tailing axle of motor, and it comprises fixed block and rubber ring, have a cylindrical hole in the described fixed block, described rubber ring is fixed in the cylindrical hole.
Adopt above structure, the utility model compared with prior art has the following advantages: the utility model is installed on the tailing axle of motor shaft, tailing axle is inserted in the rubber ring, the utility model is fixed on the casing of motor, like this, motor shaft rotates, and the utility model is fixed, and motor will produce certain frictional force with rubber ring when rotating, and therefore will be subjected to certain damping, and when motor cuts out, motor shaft can be rotated further owing to action of inertia, and under the effect of this damping, motor just is difficult to rely on inertia to drive decelerator, finally play effective braking, reduce the effect of inertia of motor motor.Stop with electromagnetism and to compare, have simple in structure, convenient for maintaining, advantage that cost is low, in the middle of lowering or hoisting gear, in uphill process, disable motor or sudden power, on the goods carried too heavily overload because the action of gravity meeting descends and the trend that makes the motor counter-rotating is arranged, under the effect of damping brake device, can effectively prevent the motor counter-rotating.
As improvement, described fixed block inside is made hollow, and has screw hole on fixed block, inserts lubricating oil within it by screw hole, adopts screw that screw hole is sealed, and described sealing ring communicates with the inside of fixed block.Like this, lubricating oil just can penetrate into rubber ring, rubber ring with the process of motor shaft friction in not fragile.
Description of drawings
Accompanying drawing is the structural representation of the utility model motor damping brake apparatus.
As shown in the figure 1, fixed block, 2, cylindrical hole, 3, rubber ring, 4, screw hole, 5, screw.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Motor damping brake apparatus of the present utility model, described motor damping brake apparatus is installed on the tailing axle of motor, comprises fixed block 1 and rubber ring 2, has a cylindrical hole 3 in the described fixed block 1, and described rubber ring 2 is fixed in the cylindrical hole 3; Described fixed block 1 inside is made hollow, and has screw hole on fixed block 1, inserts lubricating oil within it by screw hole, adopts screw that screw hole is sealed, and described sealing ring 2 communicates with the inside of fixed block 1.
Claims (2)
1. motor damping brake apparatus, described damping brake device is installed on the tailing axle of motor, it is characterized in that: comprise fixed block (1) and rubber ring (2), have a cylindrical hole (3) in the described fixed block (1), described rubber ring (2) is fixed in the cylindrical hole (3).
2. motor damping device according to claim 1, it is characterized in that: described fixed block (1) inside is made hollow, and on fixed block (1), have a screw hole (4), insert lubricating oil within it by screw hole (4), adopt screw (5) with screw hole (4) sealing, described rubber ring (2) communicates with the inside of fixed block (1).
