Problems solved by technology

At present, most of the existing gearboxes for testing gear oil stirring are spur gear gearboxes, the structure is relatively crowded, and the side wall has a great influence on the oil stirring loss. The oil inside the gearbox will not be replaced during the test, and it cannot be soaked at the same time Oil and oil injection lubrication experiment, the function is relatively single, currently the gearbox for spur gear cannot effectively measure the oil churning power of the spiral bevel gear

Embodiment Construction

[0033] The present invention is described in further detail below in conjunction with accompanying drawing:

[0034] The following will clearly and completely describe the examples of the present invention in conjunction with the accompanying drawings. In order to avoid too many unnecessary descriptions, well-known structures or functions will not be described in detail in the following examples. The examples represent only a part of the present invention, not all examples. In addition, certain quantitative expressions used in the following examples may allow certain changes in quantity without changing the basic function.

[0035] Such as figure 1As shown, a spiral bevel gear churning loss testing device includes a driving motor 3 and a gear box 7, the gear box 7 is provided with a driving main shaft 5 and a driven shaft 12, and one end of the driving main shaft 5 is connected to the output of the driving motor 3. Shaft connection, the other end of the driving main shaft 5...

Abstract

The invention discloses a device and method for testing the oil churning loss of a spiral bevel gear. By setting an oil injection device in the gear box, the test of the oil churning loss of oil injection lubrication can be realized. The oil lubrication oil churning loss test greatly saves the cost and production cycle, and improves the test efficiency. The two tests are completed in the same equipment, and the front oil orifice plate and the rear oil baffle are used to reduce the gearbox side wall. The impact caused by oil loss, the overall structure and disassembly of the gear box of the present invention are relatively simple, and it supports multiple groups of different types of gears for testing, which provides the greatest convenience for testers; it can test the oil injection lubrication of different positions and angles on the gears. The influence of power loss, and the oil in the test gearbox can realize reciprocation, and the temperature of the lubricating oil inside the gearbox can be changed and maintained at will, which is suitable for testing at different temperatures and improves the test range.

Description

technical field [0001] The invention belongs to the field of bevel gear churning loss testing devices, in particular to a spiral bevel gear churning loss testing device and method. Background technique [0002] Most of the transmissions of vehicles are driven by gears, and the transmission efficiency of gears has attracted more and more people's attention. The oil churning loss of gears is one of the major reasons for the decline of transmission efficiency. At present, most of the existing gearboxes for testing gear oil stirring are spur gear gearboxes, the structure is relatively crowded, and the side wall has a great influence on the oil stirring loss. The oil inside the gearbox will not be replaced during the test, and it cannot be soaked at the same time The oil and oil injection lubrication experiment has a relatively single function. Currently, the gearbox for spur gears cannot effectively measure the oil churning power of the spiral bevel gear. Contents of the inven...
