Embodiment Construction

[0029] Combine below Figure 1 to Figure 5 The detailed description of the specific structure, installation and working conditions of the specific structure proposed by the present invention is not intended to limit the present invention.

[0030] The improvements of the present invention to the aforementioned two invention patents mainly include the following:

[0031] The first item is the addition of a toggle lever drive mechanism consisting of a swing arm 18, a swing rod 17, a hinge seat 16, an eccentric shaft 23, a slider 21, an eccentric shaft gear 22, and an eccentric shaft bearing seat 8, 59. The swing arm 18 is made of nodular cast iron. Its shape is similar to a rhombus, with rounded ends of the long axis, and processed with pin holes. The middle section of the swing arm is slightly thicker, and a long through hole is machined along the long axis. The side walls of the long through hole are polished. The pin hole at one end of the swing arm is equipped with a bronze b...

Abstract

The improvement of a driving mechanism of a crankless engine comprises ten items including: (1) a set of knuckle-joint drive mechanism in linkage with a main shaft gearwheel and a slide sleeve is added;(2) a proximity sensor is utilized to substitute an original photocell sensor; (3) two sets of small linkage mechanism for controlling a hydraulic air distribution valve are connected with a swing arm; (4)improvement of the slide sleeve structure; (5) improvement of main shaft lubrication, sealing and bearing structure; (6) improvement of a driving shaft and a driving shaft gear; (7) improvement of the intermediate shaft structure; (8) all driving gears adopt herringbone gears; (9) a tunnel type structure is adopted by the mechanism; (10) an overrunning clutch is utilized to substitute a ratchet drive, regarding the low-revolution speed high-power engine.

Description

Technical field [0001] The present invention is an improvement on the crankshaft-less engine drive mechanism provided by Chinese patent ZL200610067524.8 and US patent application 12280617, and belongs to the field of engine technology. Background technique [0002] Chinese patent ZL200610067524.8 and U.S. patent application 12280617 provide a crankshaft-less engine drive mechanism that has some disadvantages. For example, the above scheme uses a photoelectric tube as a sensor to control the ignition of the spark plug and limit the stroke of the piston, which has low reliability. The engine cannot be started using the existing starter motor scheme, but a complicated start procedure must be added to the electronic control system. Once the electronic control system fails, there will be a risk of piston collision. The fixation scheme of the intermediate wheel shaft is complicated and inconvenient to adjust. The scheme of linkage between the valve train and the piston stroke has not...
