Problems solved by technology

However, due to the lack of machining accuracy, the fit gap between the splines is too large, and the tolerance between the internal spline and the gear is out of tolerance, which reduces the accuracy of the mechanical transmission, resulting in poor contact surfaces between the tooth surfaces of the gears. Unevenness, vibration and noise during gear operation, greatly reducing product quality and service life

Abstract

The invention relates to an auxiliary tool for detecting, in particular to a detection core rod for detecting the form and location tolerance between an internal spline and an external gear pitch circle. The detection core rod comprises a core rod body, the rotation centers of the two side end portions of the core rod body are respectively provided with a center hole, a first column body, a second column body, a third column body, a fourth column body and a fifth column body are sequentially arranged on the surface of the core rod body in the axial direction, and an involution external spline is machined on the outer surface of the third column body. By means of the detection core rod, the form and location tolerance between a finished spline and a gear pitch circle can be detected, and the ex-factory pass rate is improved.

Description

Technical field [0001] The invention relates to an auxiliary tool for detection, in particular to a detection mandrel for detecting the geometric tolerance between an internal spline and an external gear pitch circle. Background technique [0002] At present, in some construction machinery, many parts are mostly connected by involute spline to transmit torque, and the cylindrical hole and shaft are matched to center to ensure the accuracy and stability of mechanical transmission. Some of these parts can only transmit torque and centering by spline connection due to structural reasons. The spline connection in mechanical transmission is mainly used for torque transmission. To achieve the centering requirement, the machining accuracy of the internal spline must be improved. , But also to improve the geometric tolerance between the spline and the gear pitch circle. However, due to the lack of machining accuracy, the fit clearance between the splines is too large, and the tolerances...
