Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 According to the lubricating oil pump transmission device of the present invention, it comprises: a crankshaft 10; a lubricating oil pump transmission shaft 30 is arranged along the central axis of the crankshaft 10, and one end is directly or indirectly drivingly connected with the crankshaft 10 to transmit the power from the crankshaft 10 to the sliding Inside the oil pump. By using the transmission shaft 30 of the lubricating oil pump for transmission, a large number of gears are replaced, the transmission chain is shortened, and the mechanical loss is reduced; the structure is simple, the weight is light, the processing is convenient, and the manufacturing cost is low.

[0026] see Figure 2 to Figure 4 A crank gear 20 is arranged between the crankshaft 10 and the oil pump transmission shaft 30 , the first end of the crank gea...

Abstract

The invention provides a lubricating oil pump drive device. The device comprises a crankshaft and a lubricating oil pump drive shaft arranged along the central axis of the crankshaft, wherein one end of the lubricating oil pump drive shaft is connected with the crankshaft in a direct or indirect driving manner so as to transmit power from the crankshaft into a lubricating oil pump. By using the lubricating oil pump drive shaft for driving, plenty of gears are replaced, the driving chain is shortened and the mechanical loss is reduced; and the device is simple in structure, light in weight and low in manufacture cost and is convenient to machine.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a lubricating oil pump transmission device. Background technique [0002] When the aviation piston engine is working, the relative displacement of the engine parts during the work is accompanied by friction and heat release. Especially when the dry surface without lubrication is relatively moving, it needs to consume more mechanical work to overcome the friction. In order to ensure reliable lubrication and cooling of the friction parts, a certain amount of lubricating oil should pass through the engine per unit time. Therefore, aviation piston engines are designed with lubricating oil pumps, and the lubricating oil pumps of aviation piston engines are generally driven by gear transmission. The structure is complicated and the weight is heavy; the involute gear processing technology is complicated, and special tools are required to process the involute tooth shape, which requires high...
