Abstract
The utility model relates to a coupling, semicircular arc slots equally and radially divided are formed circumferentially, and the semicircular arc slots are formed on the left and right couplings. Semicircular arc slots which are equally divided and corresponding to the left and right couplings are formed at the both ends of a sleeve. Spherical rollers are installed in the circular holes formed by the semicircular arc slots of the couplings and the sleeve. The utility model has following advantages compared with the prior art: the contact condition is not varied always being line contact without regard of the variation of the angle of skew when the coupling operates, so the coupling has big transfer torque, long service life and simple preparing process simultaneously.
Description
The utility model relates to a kind of coupling.
Existing gear coupling mainly comprises Left-wing Federation's axle, right shaft coupling, is with a sleeve between two shaft couplings, is meshed together by tooth between Left-wing Federation's axle, right shaft coupling and the sleeve.Because such coupling comes transmitting torque by tooth, when work, the angle of cut all may change at any time, and when the angle of cut changed, the contact of tooth was the some contact, thereby transmitting torque is little like this, and working life is low, simultaneously, the tooth processing difficulties, cost is higher.Therefore, develop a kind of novel coupling and substitute traditional gear coupling for being badly in need of.
The purpose of this utility model provides a kind of coupling, and its contact is good, transmitting torque is big, processing is simple, long service life.
The purpose of this utility model is achieved in that a kind of coupling, comprise Left-wing Federation's axle, right shaft coupling, sleeve, said jacket casing is at Left-wing Federation's axle, between the right shaft coupling, also comprise left spherical roller and right spherical roller, be processed with the semicircular arc groove that radially on circumference, distributes on Left-wing Federation's axle and the right shaft coupling, the sleeve two ends are processed with the semicircular arc groove with Left-wing Federation's axle and the corresponding five equilibrium of right shaft coupling, left side spherical roller is installed in the circular hole of Left-wing Federation's axle and the corresponding semicircular arc groove formation of sleeve left end, and right spherical roller is installed in the circular hole of right shaft coupling and the corresponding semicircular arc groove formation of sleeve right-hand member.
Semicircular arc groove on Left-wing Federation's axle and right shaft coupling and the sleeve is along the circumference five equilibrium.
Coupling comprises Left-wing Federation's axle, left side seal ring, the left end cap screw, left end cap, left side spherical roller, the flange attachment bolt, nut, packing ring, right spherical roller, right end cap, the right end cap screw, right seal ring, right shaft coupling, said sleeve divides left sleeve, right sleeve, left sleeve is enclosed within on Left-wing Federation's axle, left end cap is enclosed within on Left-wing Federation's axle, with the left end cap screw on left sleeve, seal with left seal ring between left end cap and the Left-wing Federation's axle, left sleeve and right sleeve flange attachment bolt, packing ring, nut is fixed, right jacket casing is on right shaft coupling, right end cap is enclosed within on the right shaft coupling,, on right sleeve, seal with right seal ring between right end cap and the right shaft coupling with the right end cap screw.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model coupling master pseudosection;
Fig. 2 is an A-A sectional view among Fig. 1.
The utility model coupling, comprise Left-wing Federation's axle 1, left seal ring 2, left end cap screw 3, left end cap 4, left spherical roller 5, left sleeve 6, flange attachment bolt 7, nut 8, packing ring 9, right sleeve 10, right spherical roller 11, right end cap 12, right end cap screw 13, right seal ring 14, right shaft coupling 15, left sleeve is enclosed within on Left-wing Federation's axle, left end cap is enclosed within on Left-wing Federation's axle, with the left end cap screw on left sleeve, with left seal ring sealing, left sleeve and right sleeve are fixed with flange attachment bolt, packing ring, nut between left end cap and the Left-wing Federation's axle; Right jacket casing is on right shaft coupling, and right end cap is enclosed within on the right shaft coupling,, seals with right seal ring between right end cap and the right shaft coupling on right sleeve with the right end cap screw.Also comprise left spherical roller 5 and right spherical roller 11, be processed with the radially semicircular arc groove 16 of five equilibrium on circumference on Left-wing Federation's axle and the right shaft coupling, be processed with semicircular arc groove 17 with Left-wing Federation's axle and the corresponding five equilibrium of right shaft coupling at the sleeve two ends, left side spherical roller is installed in the circular hole of Left-wing Federation's axle and the corresponding semicircular arc groove formation of left sleeve, and right spherical roller is installed in the circular hole of right shaft coupling and the corresponding semicircular arc groove formation of right sleeve.Like this, when coupling was worked, no matter how the angle of cut changed, and its contact situation is constant, always was the line contact.
Compared with the prior art the utility model has following advantage:
1, the utility model is by arc-shaped slot and spherical roller carry-over moment, and its contact form is The line contact, when the angle of cut changed, its contact form was constant, compare with unidimensional gear coupling, Institute's transmission torque improves a lot. Compare its structure with the gear coupling that transmits onesize moment of torsion Size is littler, and long service life.
2, the machined of half-arc groove of the present utility model and heat treatment are all easy than gear, ball The face roller can adopt standard component, and manufacturing cost is reduced.
3, the utility model is easy to according to requirements Design and manufacture, and operates steadily, Noise is low, and the dismounting adjustment is also comparatively convenient.
