Abstract
The utility model relates to hoisting machinery equipment, in particular relates to and discloses an electric winch which comprises a motor; the output end of the motor is provided with a pinion; a bull gear meshed with the pinion is installed on a worm shaft; a worm gear meshed with the worm shaft is matched with a winding drum shaft coaxially; the winding drum is sheathed on the winding drum shaft; and a nylon belt is wound on the winding drum. The electric winch has the superior effects of simple structure, low noise, capability of braking reliably when hoisting a rated load, and the winch is not easy to abrade as the nylon belt serves as a flexible construction member.
Description
Technical field
The utility model relates to a kind of lifting equipment, particularly be a kind of electric capstan.
Background technology
In the prior art, the driving system of electric capstan is various gear transmissions, thereby complex structure and noise are big; Because electric capstan do not have stop mechanism mostly, though the part electric capstan has stop mechanism, so the braking force out of reach load in full of stop mechanism is the workplace of the rated load, nominal load that can not be used to hoist; Electric capstan is all used the rope traction load, and steel rope weares and teares easily and ruptures, and needs running check and replacing.
Summary of the invention
At prior art complex structure and the big defective of noise, it is a kind of simple in structure that the utility model provides, and noise is low, can reliably brake when the work of the rated load, nominal load that hoists, and use nylon tape to make the electric capstan of flexure member.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric capstan comprises motor, and the mouth of described motor is a miniature gears, is contained on the worm shaft with the big gear wheel of pinion, and with worm shaft ingear worm gear and drum shaft coaxial cooperation, reel is enclosed within on the drum shaft, the nylon tape of reeling on the described reel.By the rotation of motor, drive the rotation of big miniature gears, by the effect of worm shaft, transmit torque to worm gear, drum shaft, drive the coiling of nylon tape.Worm drive is according to the design of the less angle of spiral, and less than equivalent friction angle, so transmission has self-locking property, substituted stop mechanism, worm drive is in the rear end of messenger chain, adopts bigger transmitting ratio, so simplified drive mechanism, nylon tape flexible good, not easy to wear, and noise is low.
As preferably, described reel comprises the reel end plate at bobbin trunk and two ends, has through hole on the described reel end plate, and the termination point casing of nylon tape is on bolt, and bolt passes through hole and fixes.The termination of nylon tape can be stabilized on the reel, help electric capstan tractive load reliably.
Electric capstan described in the utility model, its superior effect is simple in structure, noise is low, can reliably brake when the work of the rated load, nominal load that hoists, and it is not easy to wear to use nylon tape to do flexure member.
Description of drawings
Fig. 1 is the structural representation of electric capstan embodiment described in the utility model.
Fig. 2 is the M-M cutaway view of Fig. 1.
Fig. 3 is the reel structure scheme drawing among the electric capstan embodiment described in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawing 1-3 and the specific embodiment the utility model is described in further detail:
A kind of electric capstan as shown in Figure 1 and Figure 2, comprises motor 13, and described motor 13 is DC machine, and its mouth is a miniature gears 7, is contained on the worm shaft 5 with miniature gears 7 ingear big gear wheels 6, by the flat key transmitting torque; The rear end of worm shaft 5 is contained in 16 li of bearing seats by bearing, and the front end of worm shaft 5 is contained in 23 li of bearing cap shims by bearing, and bearing cap shim 23 usefulness fasteners are fixed on the frame 21; With worm shaft 5 ingear worm gears 4 and drum shaft 3 coaxial cooperation, by the flat key transmitting torque, reel 8 is enclosed within on the drum shaft 3, and reel 8 also is a key connecting with drum shaft 3.As shown in Figure 3, reel 8 comprises the reel end plate 25 at bobbin trunk 24 and two ends, has through hole 2 on the described reel end plate 25, and the termination point casing of nylon tape 1 is on bolt 11, and bolt 11 passes through hole 2 and fixed by nut, and nylon tape 1 is wound on the bobbin trunk 24.
By the rotation of motor 13, drive the rotation of miniature gears 7, big gear wheel 6, by the effect of worm shaft 5, transmit torque to worm gear 4, drum shaft 3, drive the coiling of nylon tape 1.
