Abstract
The invention provides a device which is fixed on an input shaft of a gear box and can quickly separate the rotating of a belt pulley from the rotation of the input shaft when over load is discovered. The device mainly comprises the following structural components: 1, a first-level input shaft; 2, a plane bearing; 3, a belt pulley; 4, a spring safety block; 5, a screw; 6, a spring; 7, a flat gasket; 8, a gland nut; and 9, a flat key. According to the invention, firstly the first-level input shaft of the original gear box is lengthened; then the belt pulley is assembled on the shaft and one end place of the belt pulley butts against one plane bearing; the belt pulley is in clearance fit with the shaft, the other end face of the belt pulley and one spring safety block are fixed together by the screw and the other half of the spring safety block is connected with the shaft by the flat key; one spring is assembled on the other half of the spring safety block and is pressed by one gland nut. The gland nut can be used for conveniently adjusting and controlling the over load; the tighter the spring is pressed, the harder the overload action capability is; and the lighter the spring is pressed, the easier the overload action capability is.
Description
Technical field
The present invention relates to a kind of gear-box overload protection arrangement, it can stop operating in the external device catastrophic failure, and before the motor overcurrent protection there was not action, can start urgent disengagement belt fast changeed and being connected of gear-box. protect motor and gear-box preferably.
Technical background
Present employed speed-changing gear box, its function are the equipment that transmits and change the output speed work done.When external device breaks down, in case can only lean on the motor overcurrent protection to open to beat make the back motor could stall. the electric prospection equipment malfunction, gently then belt fracture, heavy then speed-changing gear box foot-screw is broken, perhaps the motor feels hot burns, consequence is quite serious.
Summary of the invention
The present invention proposes a kind of being fixed on the gearbox input shaft, can find the quick automatically device that separates belt pulley and input shaft rotation of overload.Its main structural components is by (1) first order input shaft, (2) plane bearing, (3) belt pulley, (4) spring safety block, (5) screw, (6) spring, (7) flat gasket, (8) gland nut, (9) flat key.
Be contained on the axle at first with original gear case first order input shaft lengthening, and then with belt pulley, an end face can rotate freely it near a plane bearing.It is Spielpassung that belt pulley cooperates with axle, can rotate.Its other end and a spring safety block are lived with screw fixings, and second half of spring safety block is connected with axle with flat key.The structure of spring safety block connects together as a pair of garden arc gear wheel, and integral body is rotated together when compressing, and when unclamping, will throw off two flank of tooth.So this device just is equipped with a spring on another demifacet of spring safety block, compress with a gland nut.Gland nut can be regulated control to the overload load easily, and it is tight more that spring is pressed, and its overload Motor ability is also more difficult.It is more loose that spring is pressed, easy more overload action.
Beneficial effect of the present invention is to break down to start soon, and is simple in structure, easy to adjust, safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this patent is described further.
Fig. 1 is a gear-box overload protection arrangement structural representation.
Fig. 2 is a spring safety block structural representation.
(1) among the figure, first order input shaft, (2), plane bearing, (3), belt pulley, (4), spring safety block, (5), screw, (6), spring, (7), flat gasket, (8), gland nut, (9), flat key.
The practical implementation method
As long as with wrench rotational fixation nut (8), want to let it when high capacity, open jumping during use, as long as the gland nut that turns clockwise arrives to a certain degree.Want equally when hanging down load, to open jumping, arrive to a certain degree as long as be rotated counterclockwise gland nut.
