Embodiment Construction

[0011] Such as figure 1 , figure 2 As shown, the present invention is composed of an inner sleeve 1, an oil seal 2, a cage 3, a steel ball 4, an outer sleeve 5, an end tooth plate 6, a bolt 7, a sealing baffle 8, a retaining ring 9 for a hole, a gland 10, and an oil nozzle 11. ; The two inner sleeves 1 have spline through holes or inner holes with key grooves to cooperate with the corresponding shaft extensions, and the outer diameter of the inner sleeve 1 has a spherical ring boss, which is matched with the inner spherical surface of the cage 3. Two groups of steel balls 4 are installed between the inner sleeve 1 and the outer sleeve 5, and the specific number of the steel balls 4 is determined by the required transmission capacity and internal geometric dimensions; Evenly distributed on the circumference, the cross section is an elliptical or circular straight channel, and the torque is transmitted through the channel of the inner sleeve 1, the steel ball, and the channel ...

Abstract

The invention relates to a jacket-welded short CV joint coupling which is mainly used for power transmission of short distance, small inclination angle and high rotation speed in metallurgical machinery, heavy-duty machinery, mining machinery, hoisting machinery, transport machinery and other industries. The coupling consists of an inner sleeve, an oil seal, a retainer, steel balls, jackets, contrate gears, bolts, a sealing baffle, hole retaining rings, a gland and an oil nozzle, wherein the two contrate gears are installed between the two jackets, the flange bosses of the contrate gears are fixed together by the bolts, and the contact surfaces of the contrate gears are of a dentiform structure and are meshed with each other to realize power transmission from a driving end and a driven end. By dividing the original jackets into the fluted jackets and the contrate gears, the invention realizes that the jackets and the contrate gears can be respectively made of more appropriate materials and made into more appropriate dimensions, thereby greatly improving the material utilization ratio, reducing the process redundancy, lowering the materials loss and the shaping difficulty, facilitating the design and the selection of the connection type of the contrite gears, enabling the organization and the arrangement of production to be more flexible, and having a shorter processing cycle. Thus, the invention meets batch and emergency requirements of modern mechanical industrial equipment.

Description

technical field [0001] The invention relates to the technical field of mechanical component manufacturing, in particular to a short ball cage coupling for mechanical transmission. Background technique [0002] The existing short ball cage coupling is composed of inner, outer, cage, steel ball, gland, oil seal, sealing baffle, oil nipple and other parts, among them, there are many lines on the inner and outer outer, which are evenly distributed along the circumference, and the cross section is elliptical. Shaped or circular straight channels. The torque is transmitted (or in the opposite direction) through the inner sleeve channel, the steel ball, and the outer sleeve channel. The function of the cage is to keep the steel ball group always on the angle bisector of the inner and outer grooves. The power transmission between the driving end and the driven end is realized by the mutual meshing of the two outer sleeves through the teeth on the end faces. This type of short bal...
