Abstract
The utility model discloses a band pulley safety device, comprising a driven shaft and a wheel hub which sheathes the driven shaft and can be sliding. The outer side of the driven shaft is sheathed with a band pulley. One side of the wheel hub is provided with a fixed chain wheel integrated with the wheel hub. The driven shaft is also sheathed with a baffle; one sided of the baffle is provided with a movable chain wheel which sheathes the wheel hub and is in sliding connection with the fixed chain wheel through the sickle-shaped surface of the fixed chain wheel, and the other side of the baffle is provided with a compressed spring and a detection switch. While in normal use, the baffle is pressed by the compressed spring, making the fixed chain wheel to be compactly connected with the movable chain wheel for normal running; While in failure, the wheel hub and the fixed chain wheel can not move so that the movable chain wheel moves along the sickle-shaped surface of the fixed chain wheel to drive the baffle and the band pulley to simultaneously move leftward until the two chain wheels departs from each other, and then the baffle can be detected by the detection switch which simultaneously sends a signal of stopping motion to a drive motor so that the drive motor stops running. The utility model is provided with easy regulating, dependable performance, long service life and easy mounting and maintenance.
Description
Technical field
The utility model belongs to the belt transmission system in the mechanical motion, particularly a kind of belt wheel safety installations that is driven the slave end motion by motor driving, belt transmission.
Background technique
In machine driven system, the band transmission is made up of band (comprising flat rubber belting, V band, synchronous cog belt etc.) and the driving pulley and the driven pulley that are installed on driving shaft and the driven shaft, this kind of drive utilization is stretched in belt on the belt wheel by friction between them or engagement, transmitting movement and power between diaxon or multiaxis.Band transmission, stable drive simple in structure because of it, cheap, need not lubricate and cushion advantage such as shock-absorbing and be widely used in the machinery in modern age, but when stall, fortuitous event such as stuck appear in slave end, motor still drives follower by belt and rotates, burn out motor in this case easily, simultaneously under getting rid of the situation of stall, reason such as stuck, slave end do not continue motion, the damage that causes the machinery of slave end to be difficult to repair.
Summary of the invention
The purpose of this utility model is to provide a kind of can transmit stall signal, the belt wheel safety installations that drive motor is shut down to drive motor when stall, fortuitous event such as stuck appear in slave end.
For achieving the above object, the technical solution adopted in the utility model is: comprise driven shaft and the slidably wheel hub that is sleeved on the driven shaft, the outside at driven shaft is set with belt wheel, it is characterized in that: a side of wheel hub is provided with the fixedly chain wheel that is connected as a single entity with wheel hub, on driven shaft, also be set with baffle plate, one side of baffle plate is provided with to be sleeved on carves the movable chain wheel that type is slidingly connected with fixing chain wheel on the wheel hub, also is provided with stage clip and detecting switch at the opposite side of baffle plate.
Another characteristics of the present utility model are: fixedly the front end of chain wheel and movable chain wheel is one and carves the type inclined-plane; On the screw rod that stage clip is arranged on driven shaft is threaded; The opposite side of wheel hub also is provided with slide damper.
Because fixedly chain wheel of the present utility model and the employing of movable chain wheel are carved type and are slidingly connected, and the side at baffle plate is provided with stage clip, stage clip compresses baffle plate and fixedly chain wheel and movable chain wheel closely is connected under the drive of belt wheel run well when proper functioning, when breaking down wheel hub and fixedly chain wheel can't move, movable chain wheel will move along the profile of carving on the fixing chain wheel, drive the motion to the left simultaneously of baffle plate, belt wheel, contact up to the high face of two chain wheels; Baffle plate will detect by detected switch, and detecting switch sends the signal of stop motion simultaneously to drive motor, and motor shuts down.
Description of drawings
Accompanying drawing is an overall structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
Referring to accompanying drawing, the utility model comprises driven shaft 3 and the slidably wheel hub 4 that is sleeved on the driven shaft 3, side at wheel hub 4 is provided with the fixedly chain wheel 8 that is connected as a single entity with wheel hub 4, on driven shaft 3, also be set with baffle plate 5, one side of baffle plate 5 is provided with the movable chain wheel 9 that is sleeved on the wheel hub 4, fixedly the front end of chain wheel 8 and movable chain wheel 9 is an inclined-plane, fixedly chain wheel 8 and movable chain wheel 9 adopt and carve type and be slidingly connected, opposite side at baffle plate 5 also is provided with the screw rod 2 that is threaded with driven shaft 3, stage clip 1 is sleeved on the screw rod 2, lower end at stage clip 1 also is provided with detecting switch 10, the opposite side of wheel hub 4 also is provided with slide damper 7, is set with belt wheel 6 in the outside of driven shaft 3.
Working principle of the present utility model is as follows: under situation about working well, under the clamping force of stage clip 1, fixedly the type of the carving inclined-plane of chain wheel 8 and movable chain wheel 9 is engaged, cooperate closely, thereby belt wheel 6 and wheel hub 4 and fixedly chain wheel 8 and movable chain wheel 9 are synchronized with the movement, drive driven shaft 3 motions.If when stall, fortuitous event such as stuck appearred in slave end, driven shaft 3 can't move, after stall power surpassed the active force of stage clip 1, this device just began to act on.Be wheel hub 4 and fixing chain wheel 8 can't move, and the master end motion does not in time stop, still give belt wheel 6 and movable chain wheel 9 transferring rotational motion, the inclined-plane of at this moment movable chain wheel 9 will be along the fixedly inclined-plane slip of chain wheel 8, drive baffle plate 5, belt wheel 6, slide damper 7 and the motion to the left simultaneously of movable chain wheel 9, contact up to the high face of two chain wheels; At this moment baffle plate 5 will detect by detected switch 10, and detecting switch 10 sends the signal of stop motion simultaneously to drive motor, and motor shuts down, the also stop motion of parts on this device.
The utility model is the follower in the belt transmission system, is installed on the driven shaft.It is except cooperating belt movement with normal delivery motion and the power, can also be when stall, fortuitous event such as stuck appear in slave end, transmit the stall signal to drive motor, drive motor is shut down, thereby protection motor, in order to avoid burn out, prevent that also slave end from continuing motion and causing the mechanicalness of slave end, the damage that is difficult to repair under the situation of not getting rid of stall, reason such as stuck; After the slave end accident is all got rid of, can start drive motor, this device can rely on self interior mechanical mechanism to return to normal working, and normal operation can recover in system.
