Description

A kind of can the drum type tooth pivoting support of beat

Technical field

The utility model relates to pivoting support field, particularly a kind of can the drum type tooth pivoting support of beat.

Background technique

Pivoting support is a kind of large size bearing that can bear combined load, can bear larger axial, radial load and tilting moment simultaneously.

Pivoting support is turntable bearing again, and some people is also called: swivel bearing, convolution supporting.Pivoting support is applied very extensive in real industry, and being called by people: " joint of machine ", is need between two articles to do relative rotation motion, needs again the necessary important transmission part of machinery simultaneously bearing axial force, radial force, tilting moment.Along with developing rapidly of machinery industry, pivoting support is widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.

The spiral chip removal machine of long distance needs transmitting torque under the swinging state of several angle in the course of the work, and when bearing multiple load at the same time, common pivoting support structure cannot meet this duty requirements.

Summary of the invention

The utility model proposes a kind of can the drum type tooth pivoting support of beat, under bearing the operating mode of thrust load, radial load and tilting moment at the same time, allow the transmitting torque when beat several angle.

For realizing above-mentioned technical purpose, the utility model propose a kind of can the drum type tooth pivoting support of beat, it comprises outer ring, centre circle, inner ring, outer end cap and some attachment screws, described centre circle comprises outer upper ring gear and outer lower ring, outer upper ring gear is connected by attachment screw with outer lower ring, outer upper ring gear is cambered surface drum type tooth, the ring gear of outer ring and the inner headed face of outer end cap are inner ball surface, the outer upper ring gear of centre circle and the periphery of outer lower ring are outer spherical surface, the ring gear of outer ring and the outer lower ring sphere of centre circle paste merga pass combined seal ring, end cover seals, outer upper ring gear and the outer end cap sphere of centre circle are fitted, raceway between inner ring and the outer lower ring of centre circle, raceway between inner ring and the outer upper ring gear of centre circle all arranges cylindrical roller and retainer, form three row's roller type pivoting supports.

The utility model propose a kind of can the drum type tooth pivoting support of beat, structure is simple, easy to use, when outer ring is fixing, the engagement at cambered surface drum type tooth place and the cooperation of sphere can be passed through, make inner ring carry out the swing of several angle, adapted to the requirement of complex working condition, and improve teeth portion transmission stability, simultaneously easy to process, be easy to produce, there is great application value.

Accompanying drawing explanation

Fig. 1 is that a kind of that the utility model proposes can the structural representation of drum type tooth pivoting support of beat.

Embodiment

See accompanying drawing, a kind of can the drum type tooth pivoting support of beat, it comprises outer ring 1, centre circle, inner ring 7, outer end cap 8 and some attachment screws 10, described centre circle comprises outer upper ring gear 9 and outer lower ring 4, outer upper ring gear is connected by attachment screw with outer lower ring, outer upper ring gear is cambered surface drum type tooth, the ring gear of outer ring and the inner headed face of outer end cap are inner ball surface, the outer upper ring gear of centre circle and the periphery of outer lower ring are outer spherical surface, the ring gear of outer ring and the outer lower ring sphere of centre circle paste merga pass combined seal ring 3, end cover 2 seals, outer upper ring gear and the outer end cap sphere of centre circle are fitted, raceway between inner ring and the outer lower ring of centre circle, raceway between inner ring and the outer upper ring gear of centre circle all arranges cylindrical roller 5 and retainer 6, form three row's roller type pivoting supports.

The utility model propose a kind of can the drum type tooth pivoting support of beat, under bearing the operating mode of thrust load, radial load and tilting moment at the same time, allow the transmitting torque when beat several angle.
