Description
Technical field
The utility model relates to machinery manufacturing technology field, the ball cage coupling that specifically uses on a kind of metallurgy, non-ferrous metal, the petroleum machinery.
Background technique
Existing ball cage coupling mainly is comprised of master and slave moving axis, jack shaft, outer ring, inner ring, retainer, steel ball, sealing system etc., wherein there are many to be oval or circular straight flute road along even circumferential distribution cross section on transmission shaft and the outer ring, torque is transmitted (or contrary direction) through transmission shaft raceway groove, steel ball, two outer ring raceway, realizes drive end and driven end transmission of power; The effect of retainer is that the steel ball group is on the equidistant point of transmission shaft, outer ring raceway constantly; The long-acting lubricating grease that sealing system inner filling ageing-resistant performance is good, contain extreme pressure agent.By the rolling of steel ball between the straight flute road, realize axially and the compensation of angle, and in the spatial design extreme angles, can be completely achieved constant speed.But the inefficacy of ball cage coupling all is due to the Internal and external cycle raceway fatigue wear, and after the Internal and external cycle fatigue wear lost efficacy, almost wearing and tearing or wearing and tearing were very not little for the steel ball in the ball cage coupling, make the degree of wear of Internal and external cycle and steel ball asynchronous.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of spherical roller ball cage coupling, by substituting steel ball with spherical roller, to realize increasing substantially the purpose of ball cage Coupling Life.
For achieving the above object, driving shaft of the present utility model is connected with the driving shaft flange through connecting key, jack shaft drive end outer ring links to each other with the driving shaft flange through bolt and key, the drive end outer ring, many the raceways that equidistantly distribute along circumference are arranged on the driven end outer ring, and roller one and roller two are housed between the jack shaft raceway, roller one and roller two are installed in the window of retainer one and retainer two, sealing system is equipped with in the end of drive end outer ring and driven end outer ring, the driven end outer ring is connected with the driven shaft flange through bolt and key, is connected with flat key between driven shaft and the driven shaft flange; Jack shaft two ends band elastic push rod device is equipped with tip-lever support one, push rod one in the drive end axis hole that described elastic push rod device is jack shaft, collar one is equipped with in the end of push rod one, and push rod one is spun on the bolt one, and cover has spring one on the bolt one; Tip-lever support two, push rod two are housed in the driven end axis hole of jack shaft, and collar two is equipped with in the end of push rod two, and push rod two is spun on the bolt two, and cover has spring two on the bolt two, it is characterized in that: the roller one in the raceway and roller two are spherical roller; Described raceway is arc raceway groove, straight flute road or V-shaped raceway groove.
The utility model is by substituting steel ball with spherical roller, the area of contact of ball cage coupling spherical roller and Internal and external cycle raceway groove is increased, the stressed surface unit area of raceway groove stress reduces, alleviate the wearing and tearing of raceway groove, make the inside and outside circle spherical roller inner with it of ball cage coupling reach the equivalent life design, significantly improve the working life of ball cage coupling, the radial and axial error of compensate coupling is brought into play ball cage coupling superiority of effectiveness to greatest extent.
The utility model compared with prior art has the following advantages.
1, the occasion of, continuous operation large in impact force, spherical roller substitutes steel ball, the spherical roller of ball cage coupling and the area of contact of inside and outside circle raceway groove are increased, the stressed surface unit area of raceway groove stress reduces, alleviate the wearing and tearing of raceway groove, make the Internal and external cycle spherical roller inner with it of ball cage coupling accomplish equivalent life design, the working life of significantly improving spherical roller ball cage coupling.
2, from the product safety aspect, because it is stressed to have improved the inside of spherical roller ball cage coupling, rated torque and the breakdown torque of spherical roller ball cage coupling significantly improve, under the identical applying working condition, improve the safety coefficient of spherical roller ball cage coupling, reduced the unsafe factor that the fatigue failure of ball cage coupling causes.
3, make spherical roller and the cost of making the same specification steel ball increase few, medium-and-large-sized ball cage coupling particularly, the increase cost of spherical roller, shared ratio is less, has given play to greatest extent spherical roller ball cage coupling superiority of effectiveness.
If 4 rated torque and breakdown torques at spherical roller ball cage coupling do not improve (with the ball cage coupling of same specification steel ball type), under the prerequisite that cycle in working life does not prolong, the profile of spherical roller ball cage coupling can design smaller, save the design space, allow and use the device structure of spherical roller ball cage coupling compacter, purchase cost and the manufacture cost of the equipment of spherical roller ball cage coupling used in corresponding reduction.
5, can reduce frequency and the number of times of changing spherical roller ball cage coupling, reduce the director costs of maintain and replace.
6, can shorten the fault power time of changing in the spherical roller coupler life cycle, raising metallurgical, coloured and the petroleum industry economic benefit seems more obvious to quantity-produced especially.
