Abstract

The utility model relates to a hoist and traction device. The utility model comprises at least a prime mover, a speed reducer and a roller, wherein, cables are wound to the roller, and the prime mover makes rotating movement through a drive roller of the speed reducer. The utility model has an essential point that the speed reducer is a transmission bearing. The utility model has the advantages of small size, low manufacture cost, high transmission efficiency, etc.

Description

Hoisting, tracting device

The utility model relates to a kind of elevator, draw gear, particularly contains elevator, the draw gear of retarder.

Existing elevator, draw gear comprise at least: primary mover, retarder and cylinder, be wound with hawser on the cylinder, and primary mover rotates by the retarder head roll.Its weak point is: owing to adopt gear reducer to make transmission device, and make that machine volume is big, cost is also high; Because the single-stage ratio coverage of gear reducer is little, have to adopt two-stage even three grades of deceleration transmission usually again, like this,, also increased the length of messenger chain simultaneously, and hindered the raising of complete machine driving efficiency though satisfied the speed ratio requirement.

For this reason, the purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, and a kind of improved elevator, draw gear are provided, and it can reduce machine volume, cost-cutting, and improves driving efficiency.

Realize that the utility model purpose technical scheme is when having above-mentioned formation, its special character is that described retarder is a drive bearing.

And the output shaft of primary mover and the eccentric stiffener of drive bearing link, and the internally toothed annulus of drive bearing is fixed, and its transmission circle and drum shaft or cylinder link.

Perhaps, the output shaft of primary mover and the eccentric stiffener of drive bearing link, and the transmission circle of drive bearing is fixed, and its internally toothed annulus and drum shaft or cylinder link.

Compared to existing technology, because the described retarder of above-mentioned formation is a drive bearing, (be Chinese patent application number: 85200923.2 or follow-up improvement patent 87206687.8,91201091.6 or 92201375.6 described drive bearing or drivings device), and the output shaft of primary mover and the eccentric stiffener of drive bearing linked, drum shaft or cylinder and its transmission circle or internally toothed annulus link, so can be under the situation of the size that does not increase other all directions, shorten elevator effectively, the axial dimension of draw gear, even when in end that drive bearing is contained in primary mover (by its output shaft one side) or the cylinder, then from the appearance less than retarder.In other words, shared space and the weight of drive bearing of making retarder can only be equivalent to the bearing of similar specification, thereby has reduced the volume and weight of elevator, draw gear significantly, and its price of complete machine reduces by 30% than prior art; Again because the single-stage ratio coverage of drive bearing big (6～60), efficient height, compact conformation, thereby shorten messenger chain, improved the complete machine driving efficiency.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the integrally-built cutaway view of signal the utility model.

Fig. 2 is the transmission scheme drawing of second kind of embodiment.

Fig. 3 is the transmission scheme drawing of the third embodiment.

With reference to Fig. 1, this elevator, included primary mover ［ 2 ］, drive bearing ［ 5 ］ and the cylinder ［ 8 ］ of draw gear can be arranged on the support ［ 1 ］.Be wound with the hawser ［ 9 ］ that draws or promote object along cylinder ［ 8 ］ circumference, as wirerope.Described primary mover ［ 2 ］ can be motor ［ 2 ］ or combustion engine (calling motor in the following text), and motor ［ 2 ］ is done forward and reverse rotatablely moving by drive bearing ［ 5 ］ head roll ［ 8 ］ of making retarder.Structure can be more specifically: the output shaft ［ 3 ］ of motor ［ 2 ］ links with the eccentric stiffener ［ 14 ］ of drive bearing ［ 5 ］, connect as key ［ 13 ］, fix its internally toothed annulus ［ 6 ］ (can be fixed on the body), transmission circle ［ 7 ］ links with drum shaft ［ 10 ］.In fact, an end of drum shaft ［ 10 ］ can have one to be the tie-plate of one ［ 12 ］ with it, is Bolt Connection or riveted joint between this tie-plate ［ 12 ］ and the transmission circle ［ 7 ］, then links with key ［ 11 ］ between drum shaft ［ 10 ］ and the cylinder ［ 8 ］.Obviously, similarly scheme also can be a (not shown), transmission circle ［ 7 ］ directly and cylinder ［ 8 ］ link, be about to cylinder ［ 8 ］ and make shape as above-mentioned tie-plate ［ 12 ］ by an end of drive bearing ［ 5 ］, and itself and transmission circle ［ 7 ］ linked, drum shaft ［ 10 ］ then only plays idler pulley ［ 8 ］ (not holding concurrently to the cylinder transmitting torque).The present embodiment can realize the deceleration transmission in the same way between motor ［ 2 ］ and the cylinder ［ 8 ］.

Embodiment of the present utility model also can be as shown in Figure 2, that is: the output shaft ［ 3 ］ of motor ［ 2 ］ links with the eccentric stiffener ［ 14 ］ of drive bearing ［ 5 ］, fix its transmission circle ［ 7 ］ (can be fixed on the body), internally toothed annulus ［ 6 ］ and drum shaft ［ 10 ］ or cylinder ［ 8 ］ link (connecting mode is similar to such scheme).Like this, can realize reverse deceleration transmission between motor ［ 2 ］ and the cylinder ［ 8 ］.

Such scheme also can be as shown in Figure 3, be located at drive bearing ［ 5 ］ in the cylinder ［ 8 ］ or be located at the end (by output shaft one side) of motor ［ 2 ］, especially when the design and installation space is restricted (as the self-help traction device as cross-country car) then more helps shortening the complete machine axial dimension.

About the brake equipment in above each embodiment, can select magnet stopper ［ 4 ］ (as Fig. 1) for use, also can select the motor that itself has brake equipment for use, also claim tapered electrical motor.Because this belongs to known prior art, so be not described in detail.
