Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] figure 1 In order to convert linear motion into rotary motion, it is composed of rolling spline pair and rolling screw pair arranged in series; rolling spline pair is composed of outer sleeve 2, middle sleeve 4, inner sleeve 1, and steel ball 5. The purpose is to limit the inner sleeve 1 to move axially; the rolling screw pair is composed of a spiral sleeve 6, a middle sleeve 8, an inner sleeve 1, and a steel ball 5. Its function is to drive the spiral sleeve when the inner sleeve 1 moves axially. 6 Turn. Straight grooves and spiral grooves are distributed on the inner sleeve 1 . The outer sleeve 2 of the rolling spline pair is fastened on the cylinder block through the outer cylinder, flange and screw 3; the thrust bearing 7 restricts the screw sleeve 6 from moving axially but can only rotate; sports. Thus, when the piston (see I...

Abstract

A roll screw engine includes screw conerting mechanism and continuous step by step rotating mechanism, of which the screw converting mechanism is formed by connecting integral key pair and roll screwpair in series arrangement. The internal sheath of above said pairs will become a complete set with its one end or two ends to be connected with one or several piston rod in series. The continuous step by step rotating mechanism includes two sets of roll screw pair with rotating direction in reverse and exporting gear wheel as two serewing sheathes to be connected with exporting gear wheel separately through clutch. The present invention uses roll screw converting mechanism in stead of crank link mechanism to convert reciprocating linear motion of piston into continuous rotating motion.

Description

(1) The technical field [0001] The invention relates to an internal combustion engine type engine in the field of mechanical engineering, in particular to a rolling screw engine. (2) Background technology [0002] The internal combustion engine is widely used in various machinery or transportation machinery that needs to move. At present, the internal combustion engine mainly uses the crank connecting rod mechanism to convert the movement of the piston into rotation. This kind of reciprocating mechanism has side pressure on the piston, and the transmission torque changes greatly. The radial thrust is very large, there are dead spots, and there are problems such as large sliding friction loss. Therefore, the efficiency is only 0.3 to 0.4. The rotary piston engine was studied at home and abroad in the 1950s and 1960s, but the research has been stopped because the problems of sealing and materials cannot be solved. Therefore, the crank connecting rod engine is still widely use...
