Abstract
The utility model discloses an electric roller with an external transmission, which comprises a roller, a shaft, a bearing block, a support, a frame, a transmission flange, a speed reducer and a motor. The electric roller with the external transmission is characterized in that the shaft is connected with a hub of the roller through the transmission flange, two ends of the shaft are connected with the speed reducer and the bearing block respectively, the bearing block is connected with the support and the frame sequentially, the speed reducer is connected with the motor, and a flat key mounted on the shaft is matched with the transmission flange. The electric roller with the external transmission is simple in structure and more direct and convenient in checking, maintenance and overhauling since the transmission is externally positioned, and the problems of high failure rate and difficulty in overhauling of internal electric rollers are solved thoroughly.
Description
Technical field
The utility model belongs to the main drive disk assembly of the belt feeder in the field of transport machinery of colliery, i.e. transmission external motorized pulleys.
Background technology
In the supporting drive disk assembly of belt feeder, the general built-in electric cylinders that adopt more.The built-in electric cylinder is arranged in all transmission parts in the leak free cylindrical shell, and manual work can't direct viewing move and damaged condition with inspection, and temperature is higher in the cylindrical shell, and motor and parts only depend on the fluid heat radiation.In actual use, easy et out of order.
1. motor is prone to scaling loss.Because barrel high temperature, motor radiating is difficulty relatively, breaks, insulate when reducing short circuit and waiting until situation when running into oil starvation, a phase terminal external force, very easily causes motor burning.
2. parts wear.The metallic particles that mechanical component mesh in the relative motion process, friction generates is certain and other oxidation impurities remain in the fluid, and easy to clean can not cause crush injury, spot corrosion, metal surface to peel off until damaging fully to piece surface.
3. fastener becomes flexible, comes off.Motor pinion, inner holding screw etc. become flexible, come off, and can't move.
No matter the fault what reason causes all must all be disassembled repairing with motorized pulleys and could get rid of, labor manpower and time, seriously restrict the normal operation of Coal Production and transport systems.
Summary of the invention
In order to overcome the deficiency of prior art, and provide a kind of simple in structure, transmission is external, makes inspection, maintenance, maintenance more directly perceived and convenient, has thoroughly solved the high problem with the maintenance difficulty of built-in electric cylinder fault rate.
Aforesaid transmission external motorized pulleys mainly are made up of cylinder, axle, bearing seat, bearing, frame, driving flange, retarder and motor, it is characterized in that: described axle is connected with the wheel hub of cylinder through driving flange; The two ends of axle are connected with bearing seat with retarder respectively; Described bearing seat is connected with bearing, frame in order; Described retarder links to each other with motor; On the described axle flat key is installed, described flat key matches with driving flange.
Transmission principle:
The rated speed of rotation of motor, behind retarder two-stage gear reduction, the rotating speed that makes output shaft obtain stipulating.The output shaft of retarder passes to the driving flange driving flange through flat key with moment of torsion and is connected fasteningly through screw with roller hub, and head roll rotation designs a positioning step between the two, assurance bonded assembly concentricity and support strength.
Drum shaft does not participate in rotatablely moving, and the two ends of axle are separately fixed on left-hand axis bearing and the right side retarder driving flange 3, and back-up roller rotates around the line of centers of axle.
The height of left side bearing and bearing seat confirms that with the retarder height of center base fixed orifice position is identical with retarder with size, the general and interchangeability when being convenient to install.
The utility model is to above-mentioned defective and problem; On structure design, done very big improvement, the transmission parts are all external, operation under normal temperature condition; Make inspection, maintenance, maintenance more directly perceived and convenient, thoroughly solved the problem of built-in electric cylinder fault rate height and maintenance difficulty.
Description of drawings
The structural representation of Fig. 1 the utility model
The practical implementation method
Below in conjunction with description of drawings, the utility model is done further elaboration.
Aforesaid transmission external motorized pulleys mainly are made up of cylinder 4, axle 11, bearing seat 14, bearing 15, frame 17, driving flange 3, retarder 2 and motor 1, it is characterized in that: described 11 is connected with the wheel hub 6 of cylinder 4 through driving flange 3; The two ends of axle 11 are connected with bearing seat 14 with retarder 2 respectively; Described bearing seat 14 is connected with bearing 15, frame 17 in order; Described retarder 2 links to each other with motor 1; On the described axle 11 flat key 19 is installed, described flat key 19 matches with driving flange 3.Driving flange 3 time must make the positioning step of driving flange 3 pack into fully in cylinder 4 bearing seats in assembling, and two composition planes are combined closely, and guarantee that driving flange 3 is steady with the concentricity and the transfer torque of cylinder 4.Driving flange 3 is connected holding screw with cylinder 4 must use 8.8 grade high-strength screws, and Tightening moment is not less than 250N.M, guarantees the reliability of transmission.
The external safe in operation of this transmission, the unique novelty of technology.The running parts place the cylinder outside fully, work under natural environment, and motor, retarder and bearing temperature rise are starkly lower than the built-in electric cylinder; And inspection, maintenance etc. are very convenient; Equipment is moved under good environment, and except that the normal mechanical wearing and tearing, fault is generally zero.
