Abstract

The invention provides a cross-shaft type universal coupling with a spline pair. The cross-shaft type universal coupling comprises two flange forks, two cross-shaft assemblies, a spline shaft, a spline sleeve and two welding forks, the spline shaft is made of a tempered 45# seamless thick-walled steel pipe, the outer wall of a pipe body is an outer spline, and the interior of the pipe body is hollow. The cross-shaft type universal coupling has the advantages that the spline shaft is made of the tempered 45# seamless thick-walled steel pipe instead of a round-steel bar, so that under the premise of guaranteeing the original design bearing capacity, manufacturing materials of the spline shaft can be saved, usability of the spline shaft can be improved, service life of the spline shaft can be prolonged, and cost performance of products has more market competitive advantages.

Description

technical field [0001] The invention relates to the field of shaft couplings, in particular to a cross-shaft universal joint with a spline pair. Background technique [0002] The cross-shaft universal coupling is the most commonly used coupling. Using its structural characteristics, it can make two shafts that are not on the same axis or have a large bending angle or a large axial movement continue to rotate at the same angular speed, and it is reliable. Torque and movement are transmitted accurately, generally the maximum angle between the two axes can reach 35°~45°, and the angle between the two axes can be changed at any time during the operation process, and its biggest feature is: it has a large angular compensation ability , compact structure, high transmission efficiency; can be widely used in lifting, engineering transportation, mines, petroleum, ships, coal, rubber, paper machinery and other heavy machinery industries to transmit torque in mechanical shafting.
