Problems solved by technology

This kind of transmission system is currently the most widely used transmission system. For example, due to the large power, large load, and large impact load of mining equipment, the operating environment is very harsh, which can easily lead to Short time to failure, very high slip
Due to the influence of the slip rate, the transmission ratio cannot be guaranteed, and the reliability is poor, resulting in greatly reduced operating efficiency and high energy consumption
[0003] In addition, the double crank mechanism is a mechanism with poor impact resistance, which is not very suitable for mining machinery, but due to poor selectivity, it can only be used at present
In addition, this mechanism has a dead point, which may cause a start-up block or motion uncertainty in the working state

Embodiment Construction

[0027] Refer to the attached figure 1 A power conversion mechanical drivetrain is shown, which includes:

[0028] The crankshaft 2 is the power output part of the transmission system. The crankshaft is provided with two connecting rod journals 3, and the angle between the crank arms of the two connecting rod journals is greater than 15° and less than or equal to 90°;

[0029] A crank connecting rod 4, one is provided corresponding to each connecting rod neck;

[0030] The main shaft 8 is used as the power input part of the transmission system; and

[0031] The transmission parts are two sets with the same constant transmission ratio, which are correspondingly connected between the crank connecting rod and the main shaft, and are used for driving the corresponding crank connecting rod.

[0032] Regarding the crankshaft, such as figure 1 As shown, to configure the bearing housing 1, according to the inventive idea of ​​introducing multiple pins in the present invention, it se...

Abstract

The invention discloses a power drive system of power converting machinery, which comprises a crank shaft, crank connecting rods, a main shaft and two sets of drive parts with same constant drive ratio, wherein the crank shaft is a power output part of the drive system and is provided with two connecting rod necks, an included angle of crank arms of the two connecting rod necks is more than 15 degrees and less than 90 degrees; each crank connecting rod is arranged relative to each connecting rod neck; the main shaft is a power input part of the drive system; and the drive parts are correspondingly connected among the crank connecting rods and the main shaft and used for correspondingly driving the crank connecting rods. The power drive system has the advantages of high drive efficiency, no dead points, constant drive ratio and long service life.

Description

technical field [0001] The invention relates to a power conversion mechanical power transmission system. Background technique [0002] At present, there is a kind of power transmission system of power conversion machinery that uses a belt transmission mechanism as the core mechanism. This system drives a double crank mechanism with the transmission mechanism and then drives a crankshaft to rotate, and has a main shaft of the crankshaft for power output. This kind of transmission system is currently the most widely used transmission system. For example, due to the large power, large load, and large impact load of mining equipment, the operating environment is very harsh, which can easily lead to Failure in a short period of time, the slip rate is very high. Due to the influence of the slip rate, the transmission ratio cannot be guaranteed, and the reliability is very poor, resulting in greatly reduced operating efficiency and high energy consumption. [0003] In addition, t...
