Abstract

A cross-axle universal coupling relates to the universal coupling technical field, in particular to the cross-axle universal coupling for providing power transmission in mine and metallurgy industries, which comprises a flange jaw (3), cross-axles (1), a bearing outer sleeve (4), end face bearings (5), an end cap (6) and a spline pair, wherein the end face bearings (5) of the cross-axles on two ends of the coupling are sliding bearings which are arranged between an axle end of the cross-axle (1) on the flange jaw and the end cap (6). The cross-axle universal coupling can be preferentially used for the cross-axle universal coupling which is applied in milling machineries and is higher in loading, heavy in loads, discontinuous in working state and large in impact, a certain protection is provided to connecting components of the cross-axle end and the end cap and the jaw, which increases the entire service life.

Description

Universal coupling with spider

Technical field

The utility model belongs to the Hooks coupling universal coupling technical field, particularly relates to a kind of universal coupling with spider that mine, metallurgy industry provide transmission of power that is used for.

Background technique

At present, the existing universal coupling with spider of using on the rolling machinery of domestic and international many metallurgy industries and the heavy mining equipment, under abominable, high-intensity service condition, load is bigger because coupling itself withstands shocks, this load makes the surface of contact overload between cross axle axle head and the end face rolling bearing rolling element easily and produces plastic incentation, makes bearing produce bigger frictional force and causes the connected element premature failure of cross axle end cap or end cap and jaw.

When being operated in the service condition of abominable, high working strength, the rolling bearing that the universal coupling with spider end face is adopted is just quite strict to the requirement of sealing, otherwise in case there are foreign material such as dust or metal fillings to enter the premature damage that will cause bearing in the bearing; When the special occasions condition of high temperature, the rolling bearing that the universal coupling with spider end face is adopted causes that easily bearing temperature rise is too high, and greasy property reduces, thereby causes damage of bearings.

Summary of the invention

Adopt rolling bearing under the special occasions condition of abominable, high strength, high temperature for solving existing universal coupling with spider end face, the technical problem that causes parts premature failure, damage of bearings, the purpose of this utility model provides a kind of universal coupling with spider, and the load that the rolling machinery that especially can suit is used is higher, heavy load, working state is discontinuous, impact is big universal coupling with spider; And the connected element of cross axle end cap and end cap and jaw played the certain protection effect, increased whole working life.

For achieving the above object, the utility model adopts following technological scheme:

Described universal coupling with spider, it comprises: flange jaw, cross axle, bearing outside, end face bearing, end cap and spline are paid, the end face bearing of the cross axle at two ends is a sliding bearing, and sliding bearing is arranged between the axle head and end cap of cross axle on the flange jaw.

Described universal coupling with spider, the end face that sliding bearing contacts with cross axle is provided with the lubrication groove of some arcs, and lubrication groove one end extends the outer, and the lubrication groove the other end extends axis hole.

Described universal coupling with spider, the lubrication groove cross section is circular arc or rectangle.

Owing to adopt aforesaid technological scheme, the utlity model has following superiority:

This universal coupling with spider, be by its structure is improved on the basis of existing universal coupling with spider technology, be mainly used in the special occasions of high temperature such as rolling mill, by adopting the sliding end spherical bearing of making by engineering plastics, thereby make its integral body decrease to the requirement of lubricating condition, friction factor descends, and increase working life.The sliding end spherical bearing has good self lubricity, wear resistance, low friction coefficient and special seizure resistance; the plastic deformation ability of its sliding end spherical bearing is bigger; the buffer capacity of the load that withstands shocks is stronger; so just the connected element to cross axle end cap and end cap and jaw has played the certain protection effect, and increased whole working life.And make the sliding end spherical bearing to air-proof condition require relatively lowly, and working life is longer, exactly can adapt to this abominable Environmental Conditions, thereby cost of production is reduced greatly.
