Abstract

The utility model relates to a drum-shaped roller universal coupling which comprises a flange seat, an inner tooth ring, an outer tooth sleeve, a screw bolt, an end cover, a spline shaft and a blocking ring, wherein the left end of the flange seat is connected with the outer face by the screw bolt through an end face key and a centering rabbet. The utility model is characterized in that the inner tooth ring is split with the flange seat to form a tooth inserting shape, the inner tooth ring is connected with the outer tooth sleeve by a plurality of drum-shapes rollers which are uniformly distributed, and the inner tooth ring is integrally connected with the end cover at the right end of the flange seat by the screw bolt. The utility model has the advantages of large transmission capability and long service life.

Description

The barrel shaped roller Hooks coupling universal coupling

One, affiliated technical field

The utility model relates to a kind of coupling, refers in particular to a kind of Hooks coupling universal coupling.

Two, background technique

At present, the universal coupling with spider of extensive use in China's mechanical transmission fields, through updating, its transmission capacity is enhanced, as: Chinese patent disclosed " ball coupling " (ZL92212131.1, CN2121567U), " ball Hooks coupling universal coupling " (ZL96221510.4, CN2266054Y) and " oval roller coupling " (ZL00230444.9, but still do not satisfy the requirement of mechanical transmission CN2435564Y) etc., to its transmission capacity and working life.

Three, model utility content

The purpose of this utility model is to provide a kind of barrel shaped roller Hooks coupling universal coupling, and its transmission capacity is big, long service life.

For achieving the above object, the solution that the utility model is taked is: a kind of barrel shaped roller Hooks coupling universal coupling, comprise flange seat, ring gear, external tooth cover, bolt, end cap, splined shaft and back-up ring, the flange seat left end connects with the outside with bolt by straight end-face key, centering seam, it is characterized in that ring gear and flange seat are separately made tooth embedding shape, there are several equally distributed barrel shaped rollers that ring gear is linked to each other with external tooth cover, with bolt ring gear and end cap are linked to be an integral body at the flange seat right-hand member.

The utility model adopts the split manufacturing, makes full use of good material and by the transmission barrel shaped roller, has improved overall structure precision and intensity, thereby transmission capacity is improved more than 20%, can increase the service life more than one times.It is specially adapted to metallurgical machinery and heavy machinery transmission.

Four, description of drawings

Fig. 1 is present embodiment master pseudosection (having omitted another universal joint).

Fig. 2 is the A-A sectional drawing among Fig. 1.

1, flange seat, 2, ring gear, 3, external tooth cover, 4, barrel shaped roller, 5, bolt, 6, end cap, 7, splined shaft.

Five, embodiment

Below in conjunction with embodiment and accompanying drawing thereof the good effect of the utility model and generation thereof is remake description.

Referring to Fig. 1, a kind of barrel shaped roller Hooks coupling universal coupling, comprise flange seat 1, ring gear 2, external tooth cover 3, bolt 5, end cap 6, splined shaft 7 and back-up ring, flange seat 1 left end connects with the outside with bolt by straight end-face key, centering seam, it is characterized in that ring gear 2 and flange seat 1 are separately made tooth embedding shape, there are several equally distributed barrel shaped rollers 4 that ring gear 2 is linked to each other with external tooth cover 3, with bolt 5 ring gear 2 and end cap 6 are linked to be an integral body at flange seat 1 right-hand member.This structure can improve main part ring gear 2 split manufacturings part precision and intensity and be convenient to change spare part, can rationally utilize steel.

Referring to Fig. 2, exact position by a plurality of barrel shaped rollers 4 of key component links to each other ring gear 2 and transmits big torque with external tooth cover 3, therefore designing and calculating is the umbilical point contact stress, and its admissible value is more much higher than other proof stress value of bending, turning round state, so can improve transmitting torque.Again because its contact is a barrel shaped roller 4, so its friction ractor is little, efficient is high, rotate freely.

Referring to Fig. 1, the axial stretching of present embodiment is to realize by the splined shaft 7 and the spline pair of external tooth cover 3, its axis knuckle is that the outer spherical surface by external tooth cover 3 rotates relative to the endoporus of ring gear 2 and obtains, and general axis knuckle β=0 °～10 °, present embodiment recommend with β=0 °～6 °.
