Abstract
The utility model provides a worm transmission mechanism which comprises a worm, wherein a motion body is matched with the worm, rolling wheels are evenly arranged on the motion body at intervals, and the rolling wheels are exactly meshed with worm teeth on the outer side of the worm. During the working of the worm transmission mechanism, parts contacting with the worm teeth (8) are the rolling wheel pieces, so that the abrasion is decreased greatly, the transmission efficiency is improved, the vibration, the impact and the noise are decreased to some degrees, the working is stable, and the worm transmission mechanism also has the advantages of being high in single-stage transmission ratio. In addition, the whole structure is simple, the processing is easy, standard parts can be selected for use, the manufacturing cost is low, the worm transmission mechanism is convenient to dismantle and repair, and several damaged rolling wheels can be replaced alone, and therefore the application range is wide and the economic value is high.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of worm gearing.
Background technique
Worm drive is gear-driven a kind of, be used for to transmit motion and power between the staggered diaxon in space, is generally two shaft staggered 90 ℃, and worm geared vibration, impact and noise are all very little, and the stable working single staged transmission ratio is big, compact structure.Maximum shortcoming is that efficient is low and need the good precious materials of antifriction quality, also needs good lubricatedly in running, and existing worm drive also has operating cost and the high defective of manufacture cost under the situation of inefficiency.
Summary of the invention
The purpose of this utility model provides and a kind ofly reduces wearing and tearing, can select the worm gearing that standard piece, operating cost and manufacture cost are relatively low, improve transmission efficiency for use, overcomes the deficiencies in the prior art.
Worm gearing of the present utility model comprises worm screw, is furnished with moving body mutually with described worm screw, evenly has been spaced roller on the described moving body, and described roller just is meshed with the worm tooth in the described worm screw outside.
Worm gearing of the present utility model, wherein said moving body are gyrostat, and described roller array is at the periphery of gyrostat.
Worm gearing of the present utility model, wherein said moving body are the straight line moving body, and described roller linear array is on the straight line moving body.
Worm gearing of the present utility model, wherein said roller are the roller roller bearing of strap bolt axle and eccentric bushing and are installed on the moving body by the bolt axis on this bearing and eccentric bushing.
Worm gearing of the present utility model compared with prior art has following advantage:
1, the parts that contact with worm tooth in service are roll piece, greatly reduce wearing and tearing, have improved transmission efficiency, and vibration, impact, noise all reduce to some extent, and it is more steady to work, and has the big characteristics of single staged transmission ratio equally.
2, overall structure is simple, and easy processing can be selected standard piece for use, and is cheap, overhauls conveniently, and indivedual rollers damage and can change separately.
3, wide applications is arranged, very high economic value.

Fig. 1 is the structural representation of embodiment 1 in the utility model embodiment;
Fig. 2 is the structural representation of embodiment 2 in the utility model embodiment.
Embodiment
Embodiment 1
As shown in Figure 1: 6 is worm screw, and the two ends of worm screw 6 are provided with worm shaft bearing 5, is connected on the worm shaft bearing 5 by bearing during installation, is used for the support to worm screw 6.Be processed with trapezoidal worm tooth 8 worm screw 6.3 is gyrostat, and the center portion of gyrostat 3 is provided with wheel shaft 2, and wheel shaft 2 is connected on the bearing 1 by bearing, is used for the support to gyrostat 3.Wheel shaft 2 is spatially vertical mutually with the shaft axis of worm screw 6.Outer circumference at gyrostat 3 is evenly distributed with roller 7, and roller 7 just is meshed with the worm tooth 8 in worm screw 6 outsides.Determine the number of the roller 7 that is meshed with worm tooth 8 according to the size of transferring power.
As shown in Figure 2: 6 is worm screw, and the two ends of worm screw 6 are provided with worm shaft bearing 5, is connected on the worm shaft bearing 5 by bearing during installation, is used for the support to worm screw 6.Be processed with trapezoidal worm tooth 8 worm screw 6.9 is the straight line moving body, can form sliding pair by slideway and other parts, namely moves as straight line along slideway.Be provided with a plurality of rollers 7 of evenly spaced and linear array at the side of straight line moving body 9, roller 7 just is meshed with the worm tooth 8 in worm screw 6 outsides.Determine the total length of worm screw 6 according to the size of transferring power, guarantee to have enough rollers 7 to be meshed with worm tooth 8 simultaneously.
The worm gearing of the present utility model parts that contact with worm tooth 8 in service are roll piece, greatly reduce wearing and tearing, have improved transmission efficiency, and vibration, impact, noise all reduce to some extent, and it is more steady to work, and has the big characteristics of single staged transmission ratio equally.Overall structure is simple, and easy processing can be selected standard piece for use, and is cheap, overhauls conveniently, and indivedual rollers damage and can change separately.Wide applications is arranged, very high economic value.
The structural type of present embodiment 1 can replace existing Worm gear and worm transmission mechanism, and concrete characteristics are as follows:
1, becomes roller and worm meshing by the engagement of worm and wheel tooth, become the rolling transmission by the sliding friction transmission, kept the big characteristics of single staged transmission ratio, become efficiently by poor efficiency.
2, roller is strap bolt axle spheric roller bearing (GB/T6445.1, JB/T7754), and easy to use, great variety of goods, quality are secure, cheap.The use of supporting eccentric bushing, the convenient installation reduced the form and position tolerance precision of worm gear mounting hole significantly, and worm gear is processed without precision machine tool, only can process with special tooling equipment and instrument, reduces cost significantly.
3, strap bolt axle spheric roller bearing adopts the grease centralized lubrication, eliminates oil lubricating, has cancelled the housing of retarder, be suitable for open-air dirty environment, and the worm gear diameter is not limited, can adopt welding to wait the whole bag of tricks processing, makes velocity ratio bigger, and moment of torsion is bigger.
4, can determine the number of turns (can 1 to multi-turn) of worm gear upper roller according to the size of load, the size of number or specification also can change the number of engagement roller.Especially be suitable for the big loading device of low speed.
5, available output shaft output also can be fixed the annex as reel and so in the worm gear both sides, the structure of simplified apparatus.
6, worm gear can be by along the tangential a plurality of worm drive of circumference, and a worm screw also can drive a plurality of worm gears of different direction.
7, can drive and rotatablely move, also can drive straight line motion (as embodiment 2), straight line motion also can precisely be located by the twin worm pretension.
8, has the worm and gear transmission simultaneously, the feature of pin tooth transmission and rolling screw transmission.
