Abstract

The utility model relates to a novel universal spindle which comprises Morse shafts, spherical hinges and an intermediate shaft. One end of each Morse shaft is manufactured to be cone-shaped, and is rapidly inserted into a to-be-connected part in a rigid connection mode. The other end of each Morse shaft is manufactured to be U-shaped, and is connected with a spherical hinge in a hinged mode. The spherical hinges are spherical. Grooves which are matched with the U-shaped end of each Morse shaft in an occlusive mode are machined on two planes which are perpendicular to each other on each spherical hinge. The intermediate shaft is a transition shaft between two spherical hinges. Two ends of the intermediate shaft are manufactured to be U-shaped, and are hinged with the spherical hinges. U-shaped connectors of the intermediate shaft can rotate after being connected with the spherical hinges. A Morse shaft, a spherical hinge, the intermediate shaft, a spherical hinge and a Morse shaft are connected in sequence, transmission of torsion and axial force can be achieved, and universal rotation can also be achieved. The novel universal spindle has the advantages of being good in angle compensation ability, compact and reasonable in structure, small in size, small in occupied space, good in bearing capacity, high in transmission efficiency, stable in carrying, low in noise, and convenient to disassemble, assemble and maintain.

Description

Novel universal spindle

Technical field

The utility model is related to a kind of novel universal shaft coupling, more particularly to a kind of novel universal spindle.

Background technology

Hooks coupling universal coupling is a kind of special shaft coupling, and traditional Hooks coupling universal coupling is formed by two fork-shaped parts and a cross part connection.In the case of the moments of torsion such as transmission, this shaft coupling weight is big, volume big, is generally not suitable for using to weight and the high occasion of size requirement, the angle maximum of this two axial lines is only capable of reaching 25 °, and installation is restricted.While its complex structure, weight are big, size is big, installation, maintenance is all inconvenient.

The content of the invention

The purpose of this utility model is to overcome the shortcomings of that prior art is present, and a kind of Universal coupling that can be realized transmitting torque, transmit axial force is provided, realize in the case of equal moment of torsion have low lightweight, noise, small volume, compact conformation, the features such as axial angle is big, transmission efficiency is high, energy-saving effect is obvious, it is convenient to install and maintain, fault rate is low, improves life-span and the overall security of shaft coupling.

Technical scheme：

To achieve the above object, the technical scheme of this practical use is：A kind of novel universal spindle, including Mohs axle, ball pivot, jackshaft, Mohs axle one end do tapered, are rigidly connected, the other end makes U-shaped, are hinged with ball pivot with connected piece quick insertion；Ball pivot is one spherical, processes the groove being mutually engaged with Mohs axle U-shaped end in mutually perpendicular two planes on ball pivot；Jackshaft is the excess axle between two ball pivots, and jackshaft two ends are all made U-shaped and are hinged with ball pivot, and U-joint can be rotated after being connected with ball pivot；Mohs axle, ball pivot, jackshaft, ball pivot, Mohs axle are linked in sequence, and realize transmitting torque, transmission axial force, can also universal rotational.

Do tapered in Mohs axle one end, conical nose does squarely, Mohs axle is connected with connected piece quick insertion, spindle nose square shaft is engaged with connected piece with transmitting torque, the Mohs axle other end makes U-shaped opening, reprocessing one exceedes the circular port of U-shaped rib profile in the middle of U openings, and Mohs axle is rotated by 90 ° after being connected with ball pivot, and circular port is engaged with ball pivot not to be fallen off and can rotate.

Ball pivot is spherical, by processing the groove being mutually engaged with Mohs axle U-shaped end in mutually perpendicular two planes at center on ball pivot, and groove other direction washes flat, and Mohs axle U-shaped end, which is inserted, to be rotated by 90 ° engaged after ball pivot groove, transmitting torque and can not fallen off.

U-shaped opening is all made at jackshaft two ends, and reprocessing one exceedes the circular port of U-shaped rib profile in the middle of U openings, and Mohs axle is rotated by 90 ° after being connected with ball pivot, and circular port is engaged with ball pivot not to be fallen off and can rotate.

The beneficial effects of the utility model

With larger angle compensation ability, axis knuckle can reach more than 25 °.

Rationally, small volume occupies little space compact conformation.

Large carrying capacity, compared with the shaft coupling of the other patterns of tactical diameter identical, the moment of torsion that it is transmitted is bigger, and this has more superiority to the restricted plant equipment of tactical diameter, its supporting scope.Transmission efficiency.Its transmission efficiency reaches 98-99.8%, for high-power transmission, and substantially, delivery is steady, and noise is low for energy-saving effect, assembles and disassembles easy to maintenance.
