Abstract
A high-power inclinable angle coupling comprises an inner gear sleeve, a half coupling, an end cover and an intermediate shaft, wherein the half coupling extends into the inner gear sleeve, the inner surface of the inner gear sleeve is provided with equal axial semi-cylindrical straight grooves matched with steel balls on the half coupling, the outer surface of the half coupling is provided with a plurality of parallel elastic arc flat keys, and springs are arranged at the bottoms of the arc flat keys. For changing the line contact transmission defect of former single-row steel ball key and sphere cylinder key, the utility model discloses a be equipped with the spacing step of elasticity circular arc flat key on the half-coupling and be furnished with the angle, make it at the arbitrary angle during operation of big inclination work occasion, all be the face contact to improved transfer function, transmission steady and prolonged life greatly.
Description
(1) technical field:
But the utility model relates to a kind of high-power inclination angle coupling.
(2) background technique:
Notification number is that the utility model patent of CN2385139Y discloses, and a kind of " large inclined angle coupling " is made up of internal tooth casing, half-coupling, end cap and jack shaft, have the axial half-cylindrical straight trough of equal portions on the internal surface of internal tooth casing, on half-coupling, have the radially cylindrical hole of equal portions, be provided with the hemispherical head cylinder steel ball that spring has reached the key effect in each cylindrical hole.This patent has when working under the angle occasion between larger axis, the invar ball is line style with the surface of contact of the half-cylindrical straight trough of half-coupling outer surface and contacts (being the contact of point of contact or tangent-type), make between the half-cylindrical straight trough of steel ball and half-coupling outer surface because of the wearing and tearing gap increases, thereby influence the life-span of stationarity, power and the use of transmission.
(3) summary of the invention:
The purpose of this utility model promptly is to overcome the above-mentioned defective that prior art exists, and provides a kind of stable drive, power stronger, but longer service life and be suitable for a kind of high-power inclination angle coupling that the angle occasion is used between larger axis.
The purpose of this utility model is to be achieved through the following technical solutions: the utility model is by internal tooth casing, half-coupling, end cap and jack shaft are formed, a left side, right two-end structure is identical, jack shaft is assemblied on the half-coupling, half-coupling stretches in the internal tooth casing, having the axial half-cylindrical straight trough of equal portions and the steel ball on the half-coupling on the internal surface of internal tooth casing is complementary, in the utility model, on the half-coupling outer surface, be provided with a plurality of and steel ball elasticity circular arc flat key arranged side by side, the one head is oblate arc shape, the other end is a cylinder, cylinder and oblate arc connecting part be the angulation limited step then, oblate arc partly stretches in the half-cylindrical straight trough on the internal tooth casing, is provided with spring in the bottom of column part.
For further realizing the purpose of this utility model, the utility model can radially have the steel ball bowl on the half-coupling outer surface, in be provided with the steel ball of key effect, the steel ball key is not moved about arbitrarily in the R keyway, thereby can avoid coupling to produce vibrations at the volley and the steel ball displacement, change former inclination angle state, thereby caused the damage of coupling.
But high-power inclination angle of the present utility model coupling, the circular arc flat key that is provided with spring that adopts and first cylinder straight trough of internal surface of internal tooth casing fit tightly, and is furnished with the angle limited step, when making it the unspecified angle work of angle occasion between larger axis, all be with internal tooth casing in the semicolumn groove become face to contact, change the line Contact Transmission state of former single-row steel ball key and sphere round key, thereby increased moment of torsion, improved propagation function, stable drive greatly and prolonged the life-span of using.
(4) description of drawings:
But Figure 1 shows that the half of structure half sectional view of high-power inclination angle coupling.
Figure 2 shows that the plan view of circular arc flat key among Fig. 1.
Figure 3 shows that the side view of circular arc flat key among Fig. 1.
Figure 4 shows that the plan view of circular arc flat key among Fig. 1.
(5) embodiment:
Provide specific embodiment of the present utility model below in conjunction with Figure of description.As shown in Figure 1, but this high-power inclination angle coupling is by internal tooth casing 1, half-coupling 5, end cap 4 and jack shaft 6 are formed, a left side, right two-end structure is identical, be symmetric form, jack shaft 6 links with bolt and nut and half-coupling 5 by spacer flanger, coupling 5 stretches in the internal tooth casing 1, have the bowl-shape hole of equal portions on the half-coupling 5, in be provided with the steel ball 2 of key effect, having the axial half-cylindrical straight trough of equal portions and the steel ball 2 on the half-coupling 5 on the internal surface of internal tooth casing 1 is complementary, as Fig. 2, Fig. 3, shown in Figure 4, be provided with a plurality of and steel ball 2 elasticity circular arc flat key 3 arranged side by side on half-coupling 5 outer surfaces, one of circular arc flat key 3 is oblate arc shape, and the other end is cylindrical, oblate arc shape partly stretches in the half-cylindrical straight trough on the internal tooth casing 1, is provided with spring 9 in the bottom of column part.In the utility model, the outer surface that half-coupling 5 stretches into internal tooth casing 1 part can be designed to the arc surface type, and end cap 4 is installed in the end of internal tooth casing 1, is provided with 8 dustproof and seal actions of heat-resisting asbestos cloth 7 and seal ring between internal tooth casing 1 end and end cap 4.
Claims (2)
- But 1, a kind of high-power inclination angle coupling, form by internal tooth casing (1), half-coupling (5), end cap (4) and jack shaft (6), left and right two-end structure is identical, jack shaft (6) is assemblied on the half-coupling (5), half-coupling (5) stretches in the internal tooth casing (1), the axial half-cylindrical straight trough and the last steel ball (2) of half-coupling (5) that have equal portions on the internal surface of internal tooth casing (1) are complementary, and end cap (4) is installed in the end of internal tooth casing (1).It is characterized in that: on half-coupling (5) outer surface, be provided with a plurality of and steel ball (2) elasticity circular arc flat key (3) arranged side by side, the one head is oblate arc shape, the other end is a cylinder, cylinder and oblate arc connecting part be the angulation limited step then, oblate arc partly stretches in the half-cylindrical straight trough on the internal tooth casing (1), is provided with spring (9) in the bottom of column part.
