Abstract
The utility model relates to a drum-shaped dentition formula shaft joint, which comprises a shaft-housing, an internal gear ring, an outer gear sleeve, a bolt, and an end closure, two ends of the shaft joint are directly connected with a machine shaft. The utility model is characterized in that the internal gear ring and the shaft-housing take the shape of a jaw, the internal gear ring and the outer gear sleeve are connected by a plurality of drum-shaped rollers distributing evenly, the internal gear ring and the end closure are connected into one by bolts on the right end of the shaft-housing. The utility model is separately manufactured, which is capable of making full use of material. A high admissible point contact stress is achieved through driving the drum-shaped rollers, which improves strength and precision of the integral structure, thereby the drive capability is improved 20%-93%, and the useful life can be extended more than twice. The utility model substitutes general drum-shaped dentition formula shaft joint and is especially suitable for drive of metallurgy machinery and heavy machinery.
Description
The utility model relates to a kind of coupling, refers in particular to a kind of drum-shaped tooth type shaft coupling.
Common drum-shaped tooth type shaft coupling transmission capacity is little, and working life is short.In order to improve its working life, Chinese patent once disclosed a kind of " novel drum-shaped tooth type shaft coupling " (ZL00241041.9, CN2457397Y), owing to make running more steady, therefore prolonged the working life of drum-shaped tooth type shaft coupling, but still do not satisfied the requirement of mechanical transmission its transmission capacity and working life.
The purpose of this utility model is to provide a kind of drum-shaped tooth type shaft coupling, and it is remarkable that it improves the transmission capacity effect, long service life.
For achieving the above object, the solution that the utility model is taked is: a kind of drum-shaped tooth type shaft coupling, comprise axle sleeve, ring gear, external tooth cover, bolt, end cap, the coupling two ends directly connect machine shaft, it is characterized in that ring gear and axle sleeve make 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 axle sleeve right-hand member.
The utility model adopts the split manufacturing, can make full use of good material and a very high contact stress of allowing be arranged, improve overall structure precision and intensity, thereby make transmission capacity improve 20%～93% by the transmission barrel shaped roller, effect is remarkable, can increase the service life more than one times.It replaces common drum-shaped tooth type shaft coupling, is specially adapted to metallurgical machinery and heavy machinery transmission.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is a present embodiment master pseudosection.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Referring to Fig. 1, a kind of drum-shaped tooth type shaft coupling, comprise axle sleeve 1, ring gear 2, external tooth cover 3, bolt 5, end cap 6, the coupling two ends directly connect machine shaft, it is characterized in that ring gear 2 and axle sleeve 1 make 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 axle sleeve 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, owing to linking to each other ring gear 2 with external tooth cover 3, the exact position by a plurality of barrel shaped rollers 4 of key component transmits big torque, 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.
