Abstract
The utility model relates to a motor-driven rotary drum for a conveyor, in particular to an external motor-driven rotary drum. The external motor-driven rotary drum can be divided into two types, namely a WD type external motor-driven rotary drum and a WD2 type external motor-driven rotary drum. The external motor-driven rotary drum comprises a motor, a coupling and a rotary drum body which are connected in sequence, wherein an input shaft is arranged at the right end of the rotary drum body, a supporting shaft is arranged at the left end of the rotary drum body, a small gear is arranged at a shaft end of the input shaft inside the rotary drum body, the small gear is meshed with a big gear, one section of the right shaft end of a shaft where the big gear is located is directly machined into a gear shaft, the gear shaft is meshed with an inner gear ring, the inner gear ring is fixedly connected with a right end cover inside the rotary drum body, and a bearing is arranged at the left end of the gear shaft. According to the external motor-driven rotary drum, an inner gear ring transmission structure is adopted, the number of the gears is reduced, the structure and the size are optimized, the requirements for different belt speeds are met, and usability of products are improved. The external motor-driven rotary drum has the advantages of being stable in transmission, large in bearing capacity, strong in overload capacity, small in noise, and easy to maintain.
Description
Technical field
The utility model relates to a kind of transport plane motorized pulleys, i.e. electric roller with external.Trademark: WD type electric roller with external and WD2 type electric roller with external.
Background technology
In the prior art, motorized pulleys have been widely used in the fields such as harbour, mine, metallurgy, cement, chemical industry, power plant.Electric roller with external comprises and connects in turn motor, coupler, barrel; The barrel right-hand member has input shaft, and left end has pivot shaft.Electrical motor and cylinder input shaft are by the coupler direct connection, and the motor main shaft rotation is transferred to the cylinder inner gear structure by input shaft, the rotation of head roll body.Its shortcoming is that the cylinder inner gear structure adopts the external tooth wheels to connect, and huge structure takes up room, and transmitting ratio is little, can not satisfy different belt speed requirements.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, the rational electric roller with external of speed change for above-mentioned deficiency.
Technical solution of the present utility model is: electric roller with external comprises connecting in turn motor, coupler, barrel; The barrel right-hand member has input shaft, and left end has pivot shaft.The input shaft axle head has miniature gears in the barrel, and miniature gears and big gear wheel engagement, one section of the right axle head of big gear wheel place axle directly are processed into gear wheel shaft, and this gear wheel shaft meshes with an internally toothed annulus, and this internally toothed annulus is captiveed joint with the interior right end cap of barrel; The big gear wheel place left axle head of axle is overlapped on the pivot shaft bearing.
Electric roller with external is the novel driving device of belt conveyer, the actuating device that it can replace now widely used electrical motor-retarder-driving drum to form.Can add holdback or drg according to customer requirements, make cylinder have check or braking function.As: distribution transforming is change-speed motor frequently, can carry out speed control by constant torque etc. to cylinder.Electric roller with external has good sealing property, can be used for dust and reaches greatly moist muddy place.
The utility model has the advantages that: 1, adopt the internally toothed annulus drive mechanism, save gear quantity, structure, volume are optimized, and can satisfy the requirement of different belt speed, improve the product in-use performance.2, stable drive, load-carrying capacity is large, and overload capacity is strong, noise is low, maintenance is simple.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
The specific embodiment
Referring to Fig. 1, electric roller with external comprises and connects in turn motor 17, coupler 16, holdback 15, right support abutment 14, right flanged shaft 12, input shaft 13, barrel 7; Barrel 7 right-hand members have input shaft 13, and left end has pivot shaft 11(or claims left flanged shaft).Barrel 7 interior input shaft 13 axle heads have miniature gears 5(or claim mill pinlon), miniature gears 5 and big gear wheel 4 engagements, one section of the right axle head of big gear wheel 4 place axles directly is processed into gear wheel shaft 3, this gear wheel shaft 3 and internally toothed annulus 2 engagements, this internally toothed annulus 2 is captiveed joint with right end cap 1 in the cylinder, and internally toothed annulus 2 rotates and drives barrel 7 rotations.Gear wheel shaft 3 left ends have bearing 6.Other component names is as follows: oil filler plug 9, left support abutment 2, left end cap 8.
Electric roller with external can also adopt two-stage or three grades of fixed gear axle slowing-down structures, can satisfy the requirement of different belt speed; Electric machine external, heat radiation and easy to maintenance, highly versatile, gear adopt seven class precisions, have stable drive, and load-carrying capacity is large, and overload capacity is strong, noise is low, safeguard the characteristics such as simple; Barrel 7 interior retarders adopt oil immersed type lubricated, make the lubricated more reliable of retarder; Barrel 7 surfaces can cold bonding rhombus glue face or chevron pointing glue face also can cast glue, improved surface friction coefficient, reduced the tension force of load-transfer device, thereby prolonged the service life of adhesive tape, and reduced the consumption of power energy savings.
Claims (1)
