Abstract
Disclosed is a transmission of an engine valve mechanism, referring to an engine. The utility model provides a transmission of an engine valve mechanism, which has the advantages of compact structure, less space, lower cost, convenient maintenance, low working noise and small power loss. The transmission comprises a power generator on the engine. Rotors in front of the power generator drive gears to mesh with crankshaft gears of an output end of an engine crankshaft. A camshaft is arranged at the rear end of the rotors of the engine to drive the gears, and drives the gears to mesh with timing gears on the camshaft of the engine valve mechanism.
Description
Technical field
The utility model relates to motor, especially relates to a kind of transmission device of engine valve actuating mechanism.
Technical background
The engines distribution driving mechanism comprises camshaft, intake valve and exhaust valve, and the switching of intake valve and exhaust valve is by camshaft control, and the rotating power of camshaft is that the clutch end by engine crankshaft obtains through the transmission device transmission.At present, when camshaft and bent axle distance were far away, its transmission device generally had two kinds of forms:
1) adopt chain transmission: such driving mechanism is fit to high relatively rotary speed working, and chain transmission is higher relatively to technical requirements, the requirement on machining accuracy height, and chain is easy to wear, and the distribution device timing easily produces deviation.
2) adopt the intermediate gear assemblies transmission: such driving mechanism is more because of intermediate gear assemblies, and it is bigger to take up room, and operation inertia is big, and vibration influence the distribution precision greatly during high rotary speed working, and the engine power loss is many, assembly precision requirement height, and cost is also higher.
Summary of the invention
The purpose of this utility model provides a kind of compact structure, it is little to take up room, cost is lower, be convenient to safeguard, operating noise is little, the transmission device of the engine valve actuating mechanism that power loss is few.
The utility model comprises the generator on the motor, the rotor driven gear of generator front end and the crankshaft gear engagement of being located at the engine crankshaft output terminal, rotor rear end at generator is provided with camshaft drive gear, camshaft drive gear and the timing gear engagement of being located on the camshaft of engine valve actuating mechanism.
Described camshaft drive gear is a bevel gear, and timing gear are bevel gear.
Described camshaft drive gear is a worm screw, and timing gear are worm gear.
Described rotor driven gear is preferably bevel gear, and described crankshaft gear is preferably bevel gear.
The also variable motor that is changed on the motor of generator on the described motor, as the motor on the motor of mixed power formula, technological scheme is identical; Or being transformed to the dual-purpose motor (motor that has is provided with) that has the generating and drive two kinds of functions, technological scheme is identical.
Owing to adopt said structure, the utility model utilizes generator on the motor or the motor part as transmission device dexterously, only needing to load onto 1 camshaft drive gear (being preferably bevel gear or worm screw) in the rear end of generator or motor meshes with camshaft timing gear, engine power can be passed to camshaft, thereby make distribution device work.This shows that the transmission device when the utility model is can be with original camshaft and bent axle distance far away is simplified greatly, saves the space, the few compact structure of dirivig member reduces the transmission device noise, makes transmission device work more stable, be more convenient for also safeguarding that engine power loss simultaneously also reduces.
