Abstract
The utility model relates to a rotary face envelope rolling type point engagement ring surface worm gearing, which is composed of an envelope worm and a worm wheel, wherein, the worm wheel is composed of a worm wheel body and a plurality of independent rolling units arranged on the periphery of the worm wheel body with specific rotary tooth shape faces. Each of the independent rolling unit is composed of a rotary element, a rolling element, a supporting element, etc. and is installed on the worm wheel body to form rolling teeth on the worm wheel body. The working shape face of the envelope worm and the working shape face of the independent rolling units form a point engagement transmission pair according to a media point engagement principle. The gearing has the advantages of high transmission efficiency, light transmission, strong adaptability to manufacturing and assembling error, small wear, low noise and long service life. The utility model not only can be used for decelerating rotation, but also can be used for accelerated transmission.
Description
The utility model belongs to the turning surface double enveloping worm transmission device of reduction of speed or raising speed.
Worm drive is power and the motion that is used for transmitting between the alternating axis of space.It has compact structure, stable working, can realize advantages such as big speed ratio transmission, thereby extensive use in engineering.But the axis of worm geared worm gear and worm screw interlocks, at conjugate tooth profiles point of contact place speed of related movement always greater than the peripheral velocity of worm screw or worm gear.Therefore slide relative is big between conjugate tooth profiles, frictional power loss is big, and transmission efficiency is low, normal cylindrical worm gear drive efficient has only 30～50%.In order to improve transmission efficiency, many experts and scholars will add the 3rd member roller tooth between worm and wheel two members, reduce slide relative between conjugate tooth profiles with this.Successively developed the transmission of roller enveloping worm, pinwheel worm drive, the transmission of tapper double enveloping worm.Although these novel worm drive have reduced the slide relative between conjugate tooth profiles to some extent, improved transmission efficiency, still exist some to need improvements.Such as:
(1) because the engagement driving mode that adopts line (or face) contact between the roller tooth working profile on enveloping worm working profile and the worm wheel body, thus these transmissions still to belong to slip in itself be the transmission of leading.Therefore, on the worm wheel body working profile of the working profile of roller tooth and enveloping worm or and the supporting element of roller tooth between still have very big relative sliding velocity, transmission efficiency is still very low.
(2) to make, the bad adaptability of assembly error, to make, the required precision height of assembling.
Above-mentioned deficiency is very big to the usability and the manufacture cost influence of worm gearing.
The purpose of this utility model provides a kind of novel rotation bread network rolling type point gearing toroid helicoids worm transmission device that has independent rolling unit.It can keep the advantage of existing toroid helicoids worm transmission, and can also overcome the deficiency of present toroid helicoids worm driving mechanism, improves transmission performance, improves the adaptability to manufacturing, assembly error, improves transmission efficiency and working life significantly.
The technical solution that the utility model proposes is: turning surface envelope rolling type point gearing toroid helicoids worm transmission device is made up of enveloping worm I and worm gear, its technical characteristics is, worm gear is to be made of worm wheel body II and several independent rolling unit III with specific revolution flank profil face of evenly being contained on the worm wheel body circumference, sees accompanying drawing 1.Enveloping worm I is shaped as toroidal surface, and its working profile is the specific wide face of turning surface double enveloping worm; The working profile A of the turning member on the independent rolling unit III and toroid helicoids worm working profile constitute the point gearing transmission.Being equipped with between the worm gear of independent rolling unit and the turning surface double enveloping worm can be the outer gearing transmission, sees accompanying drawing 1; Can be interior engagement driving also, see accompanying drawing 2.Independent rolling unit III is by turning member 1, rolling element 2 and supporting element 3, and block 4, circlip 5 is formed.Turning member 1 is specific turning surface A with the contacted surface of worm screw working profile, and this surface is the working profile of worm gear.The annular surface that turning member 1 contacts with rolling element 2 constitutes rolling pair by rolling element 2 and supporting element 3.There is ring raceway B at supporting element 3 endoporus two ends, and rolling element 2 rolls in ring raceway, sees accompanying drawing 3.Independent rolling unit III is installed on the worm wheel body by the caudal peduncle on the supporting element 3 (external cylindrical surface), constitutes the rolling tooth on the worm wheel body.The block 4 that is used for sealing filling slot is fixed on the external cylindrical surface of turning member 1 by circlip 5.The turning member working profile of independent rolling unit is specific turning surface A, and it can be a sphere, anchor ring, and cylinder, the conical surface or other turn round formed turning surface with straight line or curve around axis.Rolling element in the independent rolling unit can be a ball, roller, and needle roller, or the combination of ball needle roller are seen accompanying drawing 3, accompanying drawing 4, accompanying drawing 5.
Technological guidance's thought of the present utility model is by adding the rolling tooth that independent rolling unit constitutes worm gear on worm wheel body, creating into the enveloping worm working profile according to conjugate curved surface principle with the wide face of the theoretical work of worm gear.The worm screw working profile is the envelope surface of the wide face of theoretical work under special position and speed ratio condition of worm gear, and promptly the worm screw working profile is the conjugate surface of worm gear working profile.According to the rolling type point gearing transmission between media point engaging principle and technology realization worm gear and the worm screw.Thereby increase substantially transmission efficiency and working life.Reduce receptance effectively to manufacturing and assembly error.And in the design of independent rolling unit with make and introduced the rolling bearing design and manufacturing technology, not only can improve the transmission performance of mechanism, also help reducing design and manufacture cost, the standardization of being more convenient for, producing in serial form.
The utlity model has the transmission efficiency height, Windsor, it is little to wear and tear, and noise is low, and heating is few, characteristics such as long service life.This transmission is not only applicable to the reduction of speed transmission, can be used for the raising speed transmission yet.Replace existing worm and gear transmission with it, have tangible economic benefit.
