Abstract
A helical gear thrust cone balancing device open type axial loading test device is characterized by comprising a motor, a test gear case and an axial thrust loader, wherein the test gear case comprises an input gear and an output gear. An output shaft which is provided with the output gear is connected with the axial thrust loader. Thrust cones which are used for balancing axial thrust are arranged at two sides of the output gear. The axial thrust loader is composed of a shell, a rolling axletree, a ring sleeve, a circular pressing plate, a spring and a feed bolt. The shell is fixed on a case body of the test gear case through bolts. An inner ring of the rolling axletree is arranged on a shaft shoulder of the output shaft in a clamping mode. An outer ring of the rolling axletree is fixed on the ring sleeve. The front end of the ring sleeve is connected with the circular pressing plate through the spring. The feed bolt penetrates the side wall of the shell and is connected with the circular pressing plate. When the helical gear thrust cone balancing device open type axial loading test device is used for testing, a gear rotating device in the test gear case begins to rotate, the feed bolt compresses the spring through the circular pressing plate, deformation of the spring is capable of generating resilience, and thereby the ring sleeve provides thrust for the rolling axletree and elasticity is transferred to the thrust cones by the rolling axletree.

Side is provided with the thrust cone for balancing axial thrust, and the bevelling, inside edge of thrust cone forms the conical surface, and the both sides of the edge of input gear are provided with the conical surface matching surface that the conical surface with thrust cone matches; Described axial thrust loader is made of housing, rolling bearing, ring set, circular pressing plate, spring and feeding bolt, housing is bolted on the casing of test gear case, the interior ring of rolling bearing is fastened on the shaft shoulder of output shaft, its outer shroud is fixed on the ring set, the front end of ring set links to each other with circular pressing plate by spring, and the sidewall that the feeding bolt passes housing links to each other with circular pressing plate.
Preferably, be provided with pressure transducer between described spring and the circular pressing plate.
Preferably, described feeding bolt equally spacedly is distributed with several as the center of circle along its circumferencial direction take the center of circle of circular pressing plate.
The invention has the beneficial effects as follows: the open axial load testing machine of this spiral gear thrust cone balance device,
By being set, mechanical spring carries out the axial thrust loading, as long as can realize the thrust cone balance device is axially loaded by the feeding bolt, thereby realize the verification experimental verification of thrust cone balance device under the load effect to the test gear case, whole test unit is simple and compact for structure, and its axial load mode is simple in structure, do not need complicated hydraulic system, and it is stable to have axial force, the characteristics that vibration noise is little, make test unit not only satisfy the axial force requirement of device, and reduced the complexity of whole test unit.The present invention can solve that the conventional axial loaded volume is large, oil system is complicated, complex structure, the unsettled problem of loading, has improved the reliability of thrust cone balance device test.
Description of drawings:
Fig. 1 is one-piece construction schematic diagram of the present invention.
