Abstract
The utility model relates to an oil film clutch for the soft start of a belt conveyor with a heavy load, which is characterized in that the utility model also comprises a hydraulic oil inlet, a piston ring, a thrust bearing, and a spring, wherein, the hydraulic oil inlet is aligned with the end face of the piston ring; the piston ring is sheathed on a bearing seat; the thrust bearing is positioned between the piston ring and a thrust shaft; one end of the spring is fixed in a hole of a thrust disc; the other end is fixed on a drive shaft. The utility model can carry out two-way protection with a load to a motor and a speed reducer, can increase the service life, and can realize the soft start of the belt conveyor.
Description
The utility model relates to a kind of oil film clutch that is used for heavily loaded belt transporter soft start, belongs to the mechanical transport equipment technical field.
Existing belt transporter, generally all adopt the hard reboot mode, directly drive cylinder by heavy-duty motor by reductor, its shortcoming is under heavily loaded situation, because run up time is short, it is very big to start acceleration/accel, thereby belt tension is excessive, makes the serious surge of conveyer, running is unstable, load-transfer device skids, and starting power is big, and is uneconomical.
The purpose of this utility model is a kind of oil film clutch that is specifically designed to heavily loaded belt transporter soft start of design, improve the structure of existing oil film clutch, and it is arranged between the motor and reductor of belt transporter, make heavily loaded belt transporter realize soft start.
The utility model design-calculated is used for the oil film clutch of heavily loaded belt transporter soft start, comprise imput shaft, driven axle, upper box, lower box, left end cap, right end cap, bearing seat, thrust disc, active friction plate, driven friction, lubricating oil inlet, it is characterized in that also comprising hydraulic oil inlet, piston ring, thrust baring and spring; Described piston ring set is on bearing seat, and the hydraulic oil inlet is aimed at the end face of piston ring, and thrust baring places between piston ring and the thrust shaft, and an end of spring is fixed in the hole of thrust disc, and the other end is fixed on the imput shaft.
Effect of the present utility model is that oil film clutch provides the bidirectional protective to electrical motor and reductor load; improved the life-span; the impact of 5-7 times of rated current when having avoided electric motor starting; also avoided of the influence of conveyer shock load to retarder; owing to limited maximum delivered moment; thereby also to drive torque the excessive infringement that brings to conveyer protect good seal performance simultaneously.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:
The oil film clutch of heavy duty belt transporter soft start, comprise imput shaft (1), driven axle (14), upper box (15), lower box (20), left end cap (2), right end cap (19), bearing seat (3), thrust disc (9), active friction plate (10), the passive sheet that rubs (11), lubricating oil inlet (23), also has hydraulic oil inlet (22), piston ring (6), thrust baring (4), and spring (8), the enter the mouth end face of accurate piston ring of hydraulic pressure, piston ring set is on bearing seat, thrust baring places between piston ring and the thrust shaft, one end of spring is fixed in the hole of thrust disc, the other end is fixed on the imput shaft, imput shaft is connected with motor by coupler, left end cap is fixed by bolt and bearing seat, bearing seat is by bolt and last, lower box connects fixing, thrust baring bears axial force, on the bearing seat rigid drive shaft, cylinder body (5) and upper box interference fit, when pressure oil is entered by inlet, the promotion piston ring travels forward, promoting thrust disc by bearing (7) is used in masterpiece on the internal friction sheet, force spring application simultaneously, make the driven friction rotation by oil-shear power, driven friction and spline housing (21) engagement, spline housing links by bolt and driven axle, bearing (13) bearing radial force, support friction shoe (12), friction shoe is connected with driven axle by bolt, driven axle is connected with retarder by coupler, retarder is connected with belt roller, bearing (16) bearing radial force, baffle ring (17) is fixed with upper box, bearing (18) bearing radial force, right end cap is by bolt and last, lower box is fixed, lower box is fixing with lubrication box, and lubricating oil enters in the power-transfer clutch lubricated to friction lining by inlet.
Working process:
At first start lubricating pump and by the inlet input clutch; make the master; driven friction produces lubricant film; restart electrical motor; make the electrical motor No Load Start; coupler passes to the imput shaft of power-transfer clutch; the imput shaft splined end drives main friction lining rotation, opens Hydraulic Pump simultaneously, and hydraulic oil promotes piston makes the thrust disc of rotation move axially to active friction plate; effect by oil-shear power reaches driven friction; by the pattern chain cover power is reached driven axle, driven axle links by coupler and retarder, and retarder rotates and the operation of drive belt feeder; when shutting down; by the effect of spring, and friction lining is separated, and quit work.
