Abstract
The utility model discloses a winch, which comprises a mechanical transmission mechanism, wherein, the mechanical transmission mechanism is composed of an inner gear ring which is fixedly connected with the end surface of one side of a reel, and two planetary gears engaged with the inner gear ring. The two planetary gears are respectively arranged on double eccentric sleeves which are fixedly connected with motor shafts. The two eccentric distances of the double eccentric sleeves are in opposite directions. The number of teeth of the two planetary gears are respectively less than the number of teeth of the inner gear ring. The utility model has the advantages that the utility model adopts a planetary transmission structure with little tooth difference, and two planetary gears arranged on the double eccentric sleeves are engaged with the inner gear ring for meeting the requirement of a speed reducing ratio. The winch uses few parts and components, and the winch which has a simple and compact structure is installed on one side of the reel close to a motor. The winch is conveniently repaired, lubricating oil is conveniently filled, and the service life of the winch is extended.
Description
Technical field:
The utility model relates to mechanical field, particularly relates to a kind of winch.
Background technology:
Winch is widely used in scheduling mine car under the mine, transported material, haulage equipment, surface structures construction etc.The transmission device of the present employed winch secondary inner gear speed-changing mechanisms that are installed in the reel inner chamber that adopt more, this just brings inconvenience to installation, maintenance, and this transmission device complex structure, high material consumption, the processing and manufacturing cost is higher.
The utility model content:
The purpose of the utility model is at above-mentioned existing in prior technology not enough and a kind of compact conformation is provided, is convenient to the winch of installation and maintenance.
For achieving the above object, the utility model can be achieved through the following technical solutions:
Winch described in the utility model comprises mechanical transmission mechanism, described mechanical transmission mechanism is to be connected in the internally toothed annulus on reel one side end face, two planetary wheels that are meshed with this internally toothed annulus, on two eccentric bushings that described two planetary wheels are separately positioned on motor shaft is connected mutually; Two eccentric throw directions of described pair of eccentric bushing are opposite; Two planetary numbers of teeth are less than the number of teeth of internally toothed annulus respectively.
Described internally toothed annulus is connected in the side of reel near motor.
Advantage of the present utility model is to adopt the small Tooth Number Difference Planetary Transmission structure, is meshed with described internally toothed annulus and reaches the reduction ratio requirement by being arranged on two planetary wheels on the described pair of eccentric bushing.The used parts of the utility model are few, and are simple in structure, compact, are installed in the side of reel near motor, are convenient to maintenance, filling lubricating oil, prolonged service life of equipment.
Description of drawings:
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment:
As shown in the figure, winch described in the utility model comprises mechanical transmission mechanism, described mechanical transmission mechanism is to be connected in the internally toothed annulus 2 on reel 1 one side end faces, two planetary wheels 3,4 that are meshed with this internally toothed annulus 2, on two eccentric bushings 6 that described two planetary wheels 3,4 are separately positioned on motor shaft 5 is connected mutually; Two eccentric throw directions of described pair of eccentric bushing 6 are opposite; The number of teeth of two planetary wheels 3,4 is less than the number of teeth of internally toothed annulus 2 respectively.Internally toothed annulus 2 is connected in the side of reel 1 near motor 7, makes structure compact more like this.
