A linear reciprocating piston power machine

Abstract

The invention discloses a power machine for a linearly-reciprocating piston. The power machine comprises a machine frame, a cylinder body and a torque conveying device, wherein the cylinder body and the torque conveying device are installed on the machine frame. The piston is arranged in the cylinder body. A rack is fixedly installed on the piston and engaged with a gear A. The gear A is installed on the machine frame. The output end of the gear A is connected with the torque conveying device. By means of the piston, the rack and the gear, the reciprocating linear movement of the piston is converted into the rotation movement, the power machine which adopts rack and gear transmission and used for the linearly-reciprocating piston can do work by sufficiently utilizing early-stage high pressure of gas and tail gas, the environmental protection performance is good, the valid thermal efficiency is high, and the maximum torque is increased by 26% or above compared with the maximum torque of a crank internal combustion engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a linear reciprocating piston power machine. Background technique [0002] At present, the vast majority of internal combustion engines adopt two types of structures: crank-rod reciprocating piston type and rotor-piston type. The crank-connecting rod reciprocating-piston type has the following disadvantages: 1. At the initial stage of the power stroke, the gas pressure in the cylinder is large, but the transmission force arm is short, 2. The efficiency of the mechanism itself is not high, and there is a dead point; 3. There is alternating side pressure between the piston and the cylinder wall, and the friction loss is serious. Although the rotor-piston type overcomes some of the shortcomings of the crank-connecting rod type, it has difficulties in lubrication and sealing, which lead to high manufacturing and use costs. Contents of the invention [0003] In view of the above pr...

[0002] At present, the vast majority of internal combustion engines adopt two types of structures: crank-rod reciprocating piston type and rotor-piston type. The crank-connecting rod reciprocating-piston type has the following disadvantages: 1. At the initial stage of the power stroke, the gas pressure in the cylinder is large, but the transmission force arm is short, Resulting in less external work; 2. The efficiency of the mechanism itself is not high, and there is a dead point; 3. There is alternating side pressure between the piston and the cylinder wall, and the friction loss is serious

Although the rotor-piston type overcomes some of the shortcomings of the crank-connecting rod type, it has difficulties in lubrication and sealing, which lead to high manufacturing and use costs.
