Abstract
The invention provides a worm drive mechanism, comprising 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 engaged with worm teeth on the outer side of the worm. During the working of the worm drive mechanism provided by the invention, parts contacting with the worm teeth 8 are the rolling wheels; in such a way, 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 more stable; the worm drive mechanism also has a great drive ratio like the single-stage drive; in addition, the whole structure is simple, the processing is easy, standard parts can be selected for use, the manufacturing cost is low, the dismantling for repair is convenient and several damaged rolling wheels can be replaced alone; and therefore, the application range is wide and the economic value is quite high.
Description
Technical field
The present invention 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 diaxon of spatial intersecting, 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 large, 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 in the situation of inefficiency.
Summary of the invention
The purpose of this invention is to provide and a kind ofly reduce wearing and tearing, can select the worm gearing that standard piece, operating cost and manufacture cost are relatively low, improve transmission efficiency, overcome the deficiencies in the prior art.
Worm gearing of the present invention comprises worm screw, is furnished with mutually moving body 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 invention, wherein said moving body are gyrostat, and described roller array is at the periphery of gyrostat.
Worm gearing of the present invention, wherein said moving body are the traveling priority body, and described roller linear array is on the traveling priority body.
Worm gearing of the present invention, 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 invention 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 equally the large characteristics of single staged transmission ratio.
2, overall structure is simple, and easy processing can be selected standard piece, and is cheap, overhauls conveniently, and indivedual rollers damage and can change separately.
3, wide application area is arranged, very high economic value.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 in the specific embodiment of the invention;
Fig. 2 is the structural representation of embodiment 2 in the specific embodiment of the invention.
Embodiment
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 mutually vertical 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 traveling priority body, can form sliding pair by slideway and other parts, namely makes traveling priority along slideway.Be provided with a plurality of rollers 7 of evenly spaced and linear array at the side of traveling priority 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, ensure enough rollers 7 and be meshed with worm tooth 8 simultaneously.
The worm gearing of the present invention 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 equally the large characteristics of single staged transmission ratio.Overall structure is simple, and easy processing can be selected standard piece, and is cheap, overhauls conveniently, and indivedual rollers damage and can change separately.Wide application area 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 large 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, the form and position tolerance precision of decrease worm gear mounting hole, worm gear is processed without precision machine tool, only can process the decrease cost with Special frock device and instrument.
3, strap bolt axle spheric roller bearing adopts grease centralized lubricating, eliminates oil lubricating, has cancelled the housing of retarder, applicable open-air dirty environment, and also the worm gear diameter is not limited, can adopt welding to wait the whole bag of tricks processing, makes velocity ratio larger, and moment of torsion is larger.
4, can determine according to the size of load the number of turns (can 1 to multi-turn) of worm gear upper roller, the size of number or specification also can change the number of engagement roller.Especially the applicable large loading device of low speed.
5, available output shaft output also can be fixed in the worm gear both sides annex such as reel and so on, 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 (such as embodiment 2), straight line motion also can twin worm pretension precise positioning.
8, has simultaneously Worm Wheel System, the feature of pin tooth transmission and rolling spiral drive.
