Problems solved by technology

[0002] At present, the torque when the gear rotates cannot be detected by thermally assembling the gear on the crankshaft. Even if the assembly interference meets the requirements of the drawing, the engine failure may occur due to the rotation of the gear during actual use.
So far, there has been no literature report on a special testing device for the rotational torque of thermally assembled gears

Embodiment Construction

[0009] Such as figure 1 As shown, a thermally assembled gear rotation torque testing device includes a torque wrench 1, a torque multiplier 2, a torsion sleeve 3, and a workpiece to be tested. The workpiece to be inspected is composed of a crankshaft 6 and a gear 7, which are installed on the crankshaft assembly platform 4, and the torsion sleeve 3 is fixed on the gear 7 at the rear end of the crankshaft 6 through an internal gear; the torque multiplier 2 is installed on the torsion sleeve 3; the torque Wrench 1 is installed on the torque multiplier 2.

[0010] The crankshaft assembly platform 4 is also provided with a torque multiplier support seat 5 . Torque multiplier support seat 5 plays the role of auxiliary supporting torque multiplier.

[0011] When the present invention is used, after the torque wrench 1 is set to a certain torque, force is applied to the torque wrench 1 . If the torsion sleeve 3 drives the gear 7 to rotate, the torque value set by the torque wrench...

Abstract

The invention relates to a detection device for the rotation torque of a hot assembly gear. The detection device comprises a torque wrench, a torsion multiplier, a torsion sleeve and a workpiece to be detected. The workpiece to be detected is composed of a crankshaft and a gear, and is installed on a crankshaft assembly table. The torsion sleeve is fixed to the gear at the rear end of the crankshaft through an internal gear. The torsion multiplier is installed on the torsion sleeve. The torque wrench is installed on the torsion multiplier. Force is applied to the torque wrench with set torque, the torsion sleeve drives the gear to rotate, and therefore the torque of the hot assembly gear in the rotation process is detected. The detection device is simple and reasonable in structure and convenient to use and operate, and can accurately detect the actual numerical value of the rotation torque of the hot assembly gear.

Description

technical field [0001] The invention relates to a torque testing device, in particular to a testing device for thermal assembly gear rotation torque. Background technique [0002] At present, the torque when the gear is rotated cannot be detected by thermally assembling the gear on the crankshaft. Even if the assembly interference meets the requirements of the drawing, the engine failure may occur due to the rotation of the gear during actual use. So far, there has been no literature report on a special testing device for the rotational torque of thermally assembled gears. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a testing device for thermally assembled gear rotation torque with reasonable structure, simple manufacture, convenient operation and accurate testing. [0004] The technical solution adopted by the present invention to solve the technical problem is...
