Abstract
The utility model discloses an inertia brake, which is mainly composed of a static disk (2), a dynamic disk (3), a leaning disk (7), and a screw thread sleeve with a shaft (8). The static disk is fixed onto an electric motor end cover (1) or a speed reducer with a bolt; the screw thread sleeve with the shaft (8) is connected with an electric motor shaft; as the synchronized operation of the electric motor, the dynamic disk (3) and the screw thread sleeve with the shaft (8) which are matched through the screw threads can move along the direction of the screw thread sleeve shaft; when the screw direction is braking, the dynamic disk can be tightly close to the static disk; the inertia moment of the dynamic disk is 3.5 times larger than the frictional resistance moment among the screw threads, and the leaning disk (7) which is fixed onto the screw thread sleeve with the shaft (8) can proceed the synchronized operation as the screw thread sleeve. The inertia brake which makes use of the inertia braking can be driven by the idle work; the inertia brake can save the energy consumption, the copper material, etc; the inertia brake has simple structure, accurate suspension position of the instruction, and the safe inertia brake which needs not to be operated can be automatically controlled and braked.
Description
The utility model belongs to the break that vertical tackling system uses, and is the automatic control break that utilizes inertia-activated.
The break that known vertical tackling system uses has electromagnetic brake, is to drive with useful work, and power consumption is big, need consume the copper material and the silicon steel sheet of some when manufacturing, and its cost is higher, manufactures complexity.
The purpose of this utility model provides a kind of simple in structure, consumed energy not, the inertia brake that idle work drives.
For achieving the above object, as shown in drawings, the inertia brake of forming by quiet dish (2), Moving plate (3), by dish (7), tape spool thread bush (8), its quiet dish (2) is fixed on electric motor end cap (1) or the retarder with screw (6), tape spool thread bush (8) links with motor shaft (5), with synchronizing motors, Moving plate (3) is loaded on quiet dish and becomes screw-thread fit with thread bush (8) between coiling, can move axially along thread bush, its spiral shell is to deciding with motor rotation direction, and Moving plate is close to quiet dish when making braking; The moment of inertia of Moving plate is fixed on the thread bush (8), with thread bush run-in synchronism by dish (7) greater than frictional resistance moment between screw thread.When tired when raising machine and beginning to promote by state of rest, behind the starting electrical machinery, motor shaft (5) drives thread bush (8) and rotates together, if counterclockwise rotate, the Moving plate (3) that remain static this moment, because and the friction torque between screw thread is less than the moment of inertia of Moving plate, therefore left spiral shell to Moving plate can axially move to left along thread bush, separate with quiet dish (2) and to form certain interval, after moving a determining deviation, stop nut on the Moving plate (4) with collide and lean on by the nut (9) of dish (7), make Moving plate (3) with by coiling (7) with synchronizing motors, reach the purpose of lifting.When hanging the hurdle and rise to specified position, along with closing of electric power switch, motor is stall immediately under the effect of hanging the hurdle weight, at this moment because inertia, Moving plate still has certain momentum, and under the effect of this moment of momentum, Moving plate can axially move to right along thread bush in 1% second, can be close to quiet dish, thereby check weight.If still do not check weight after being close to quiet dish, then weight can be similar to the acceleration whereabouts of freely falling body, under the effect of weight, thread bush (8) is high speed rotating clockwise, owing to become left spiral shell to cooperation between Moving plate (3) and the thread bush (8), force Moving plate (3) to continue axially to move to right, impel tighter that Moving plate (3) and quiet dish (2) lean on, till checking weight along thread bush.
Advantage of the present utility model and good effect are: owing to be the Moving plate inertia braking, made full use of idle work, saved the driving energy consumption.Compare with existing electromagnetic brake, not only do not have the energy consumption of driving, and save copper material and silicon steel sheet, it is simple in structure, volume is little, can automatic control brake, need not operate, braking ability is flexible, safe and reliable, the instruction suspension point is accurate, and rate of descent is the loss motor soon and not.
Embodiment's accompanying drawings of the present utility model is as follows: (1) is electric motor end cap among the figure, (2) be quiet dish, be fixed on the electric motor end cap (1) with screw (6), (3) be Moving plate, become screw-thread fit with the tape spool thread bush, its moment of inertia is advisable greater than 3.5 times of frictional resistance moment between screw thread, when motor when turning clockwise, Moving plate becomes right spiral shell to cooperation with thread bush (8), otherwise then is that left spiral shell is to cooperation; If quiet dish is contained in the right side of retarder, still is that right spiral shell is to cooperation.For make motor rotation direction be fit to spiral shell to, to be held together the nut on the Moving plate with by the nut on the dish during motor wiring, after waiting to prove that motor steering is correct, can untie nut and start working, (4) are the stop nuts on the Moving plate, (5) be motor shaft, (6) be the screw of fixing quiet dish, (7) are by dish, can directly be welded on the tape spool thread bush (8), (8) be the tape spool thread bush, its screw thread can be trapezoidal.(9) be by the nut on the dish.
Claims (1)
1, a kind of inertia brake is characterized in that: by quiet dish (2), Moving plate (3), form by dish (7), tape spool thread bush (8); Quiet dish (2) is fixed on electric motor end cap (1) or the retarder, tape spool thread bush (8) links with motor shaft (5), Moving plate (3) is loaded on quiet dish and becomes screw-thread fit with thread bush (8) between coiling, and can move axially along thread bush, and its spiral shell Moving plate when making braking is close to quiet dish; The moment of inertia of Moving plate is fixed on the thread bush (8) by dish (7) greater than frictional resistance moment between screw thread.
