Abstract

The utility model discloses a slide block transmission shaft coupling with large torque and large inclination angle, which comprises a transmission disk and a shaft sleeve arranged therein, a half-bulb round pin arranged in a hole in the circumference of the shaft sleeve, wherein a slide block is arranged in an axial groove on the circumference of the transmission disk, the lower part of the slide block is provided with a concave surface for matching with the half bulb of the half-bulb round pin, the outer cylindrical surface on the upper part of the slide block is in contact with the inner cylindrical surface of an inner ring sleeved on the transmission disk. In the case of transmission, the slide block is driven by the half-bulb round pin, and drives the transmission disk through its side surface. In the case of angular displacement existing between two transmission shaft lines, the slide block slides in an axial gap of the axial groove of the transmission disk, thereby having large angular compensation, realizing large inclination angle through two shaft connection, due to surface contact transmission moment, bearing large torque. The shaft coupling is suitable for general machinery, especially heavy type mechanical transmission.

Description

Big torque, large inclined angle, slide block transmission coupling

Technical field

The utility model relates to mechanical transmission, and its big angular compensatory amount is applicable to the common mechanical transmission, especially heavy machinery transmission with the ability of bearing torque.

Background technique

Coupling is indispensable parts in the mechanical transmission, in the present big torque transmission, being known as drum type gear coupling torque transmission capability maximum generally uses, but because of it is not that face contact carry-over moment ability is very restricted, the poorer maximum of its angular compensatory amount allowable is 1.5 degree only, therefore need a kind ofly with the face contact, torque transmission capability is bigger, and angular compensatory amount allowable also is very big coupling.

The model utility content

For coupling can transmit big torque, and big angular compensatory amount arranged, the technical solution adopted in the utility model is: coupling has driving disk axle sleeve to be arranged in it, the hemispherical head round pin is set in the hole on the axle sleeve circumference, the hemispherical head of hemispherical head round pin is in the concave spherical surface of slide block, slide block is again in the axial elongated slot on the driving disk circumference, the external cylindrical surface of slide block contacts with the endoporus of outer shroud on being enclosed within driving disk, when the diaxon that is connected has the angle deviation, slide block slides in the axial elongated slot of driving disk, therefore allow big angular compensatory amount, coupled diaxon can large inclined angle, and because of the hemispherical head of the hemispherical head round pin in axle sleeve and the concave spherical surface of slide block are the spheres that matches, slide block also drives driving disk with its side simultaneously, all be the face Contact Transmission, so can transmit big torque.

The coupling end also is provided with elastic sealing ring, prevents that lubricating grease from spilling.

The effect that the utility model is useful is that torque transmission capability is big, and allows coupled diaxon large inclined angle, and the coupling volume is also little, and energy in light weight is saved a large amount of valuable alloy steel products.This coupling is applicable to all mechanical transmission, especially heavy machinery transmission.

Embodiment

Fig. 1 is a plan view of the present utility model, and Fig. 2 is a sectional view, Fig. 3,4,5,6, the 7th, and other is part figure.

Originally execute the big torque of example, large inclined angle, the slide block transmission coupling is in the hole 1a on axle sleeve 1 circumference hemispherical head round pin 5 to be set, its cylindrical body 5b is in 1a, its hemispherical head 5a is in the concave spherical surface 4b of slide block 4, slide block 4 is again in the axial elongated slot 6a of driving disk 6, the external cylindrical surface 4a of slide block 4 contacts with the inner cylindrical surface of outer shroud 3 on being enclosed within driving disk 6, axle sleeve 1 drives hemispherical head round pin 5 with hole 1a during transmission, its hemispherical head 5a driving block 4, slide block 4 its sides drive driving disk 6, when the diaxon of coupling connection has the angle deviation, because of there is axial air gap in the axial length of the axial elongated slot 6a of driving disk 6 greater than the length of slide block 4, slide block can slide in axial air gap, so allow big angular compensatory amount, coupled diaxon can large inclined angle.Because of the hemispherical head 5a of hole 1a on the axle sleeve 1 and interior hemispherical head round pin 5 thereof is and the same sphere of concave spherical surface 4b radius of slide block 4, it all is with the face contact, so can transmit big torque that slide block 4 drives driving disk 6 with its side.

Need to prove at the hemispherical head 5a of hemispherical head round pin 5 and be arranged with elastic mat 7, cylindrical body 5b is arranged with elastic mat 8, contact with the concave spherical surface 4b of slide block 4 is identical with the hemispherical head 5a that guarantees hemispherical head round pin 5, cylndrical surface, the top 4a of slide block 4 is affixed on the endoporus of outer shroud 3, so slide block 4 can slide in the axial elongated slot 6a of driving disk 6 and realizes large inclined angle.

The coupling end also is provided with elastic sealing ring 2 and holds axle sleeve 1 groove and spill to prevent lubricating grease, and guarantees that axle sleeve 1 and driving disk 6 are axially having definite position.

Be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, with reference to embodiment the utility model is had been described in detail, those skilled in the art can make amendment or replacement on an equal basis to technical solutions of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
