Abstract
Provided is tensioning mechanism of a belt conveyer. The tensioning mechanism includes a shaft coupling, a planetary decelerator, a permanent magnet synchronous motor, a power-off brake, and a rotary transformer which are sequentially connected. The tensioning mechanism is characterized in that the shaft coupling connects a bearing with the output end of the planetary decelerator, the input end of the planetary decelerator is connected with the permanent magnet synchronous motor, the tail end of the shaft of the permanent magnet synchronous motor is connected with the rotary transformer, and the permanent magnet synchronous motor is used as a system power device. Another new tensioning structure is formed by interchanging the connection sequences of the planetary decelerator and the shaft coupling.
Description
Affiliated technical field
The utility model relates to a kind of belt tensioning mechanism, and volume is little, tensile force is large.
Background technology
At present, known belt feeder stretching device is to be assembled by cylinder, planetary reduction gear, asynchronous motor, hydraulic brake, bearing brackett and base plate.But, because hydraulic braking needs extra hydraulic efficiency pressure system and power system as support, need exceptional space to lay.And the permasyn morot volume that the volume of asynchronous dynamo is compared under same power rotating speed is large.
Summary of the invention
The utility model provides a kind of stretching device, structure is that coupler, planetary reduction gear, permagnetic synchronous motor, electricity loss brake, magslip are linked in sequence, it is characterized in that, coupler is connected bearing with the mouth of planetary reduction gear, the input end of planetary reduction gear is connected with permagnetic synchronous motor, permagnetic synchronous motor is connected with electricity loss brake simultaneously, at permagnetic synchronous motor shaft end, is connected with magslip, and permagnetic synchronous motor is as system dynamic device.The order of connection of planetary reduction gear and coupler is exchanged, form another new tension structure.
Tradition tensioning device adopts hydraulic braking, and braking retardation is larger on the sensitieness impact of whole belt feeder.The utility model solves the technical scheme that its technical matters adopts: frequency conversion permanent magnet synchronous dynamo and magnet stopper are integrated in the middle of whole stretching device to the integrated design that realizes power output and control.Adopt electricity loss brake, just hydraulic braking can have been replaced, can realize faster the switching between braking and motor operating state than hydraulic braking.Meanwhile, electromagnetic brake system conserve space more.Permagnetic synchronous motor is larger than the power density of asynchronous motor, and required installing space is less.
The beneficial effects of the utility model are, can complete installation at finite space, control speed of response quicker simultaneously, and implementation is simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Fig. 1 is constructional drawing of the present utility model.
In Fig. 1:
1 is that bearing 2 is that spherical aligning coro bearng 3 is that coupler 4 is cylinder
5 is that planetary reduction gear 6 is that bearing seat 7 is that spherical aligning coro bearng 8 is bearing seat
9 for bearing 10 is for permagnetic synchronous motor 11 is for electricity loss brake 12 is for revolving change
The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
In Fig. 1, status signal is controlled motor and the energising of 11 electricity loss brakes, and motor normal operation, turns to the little rotating speed of high pulling torque by 5 planetary reduction gears by the little torque axis of high rotating speed and export, and by 3 coupler, is connected with 4 cylinders, guarantees the stable output of moment.When tension force is enough, status signal is controlled and is cut off motor and electricity loss brake power supply, guarantees that electricity loss brake is in braking mode.Total system carries out work under new operating mode.Once break down, status signal or unforeseen circumstances have a power failure, and motor and electricity loss brake can be cut off the electricity supply simultaneously, guarantee security of system.
