Abstract
The utility model relates to a kind of engine device, is specifically related to a kind of I. C. engine crankshaft device.It comprises cylinder block, is placed in the piston of cylinder block inside, and bent axle is connected with piston by connecting rod, and bent axle departs from piston centreline 20-30 degree, and it is consistent that it departs from piston direction and bent axle direction of doing work.This I. C. engine crankshaft device, bent axle departs from piston centreline several angle, the pressure that effective damper piston, connecting rod, bent axle bear, and improves the working life of structure member, is also beneficial to the working power increasing motor.
Description
Technical field
The utility model relates to a kind of engine device, is specifically related to a kind of I. C. engine crankshaft device.
Background technique
At present, existing I. C. engine crankshaft is many to be vertically connected with cylinder body, piston vertically does work up and down, cause is that 90 ° of actings are descending, piston and bent axle are subject to great recoil force, cause great pressure, very easily cause the wearing and tearing of three to piston, connecting rod, bent axle, affect its life-span, also reduce the mechanical efficiency of motor.
Model utility content
The deficiency that the purpose of this utility model is to solve piston that above-mentioned prior art exists, bent axle bears very big recoil force, provides the I. C. engine crankshaft device that a kind of piston and bent axle are not subject to recoil force.
The utility model is achieved through the following technical solutions:
A kind of I. C. engine crankshaft device, comprise cylinder block 1, be placed in the piston 2 of cylinder block inside, bent axle 4 is connected with piston 2 by connecting rod 3, and special way is that bent axle 4 departs from piston 2 center line 20-30 degree, and it is consistent that it departs from piston direction and bent axle direction of doing work.
It is that bent axle 4 departs from piston 2 center line 22.5 degree that one of the present utility model is improved, and under this deviation angle, bent axle is not only easy for installation, also can most of pressure of bearing of damper piston, connecting rod, bent axle, increases the working power of motor.
This I. C. engine crankshaft device, bent axle departs from piston centreline several angle, the pressure that effective damper piston, connecting rod, bent axle bear, and improves the working life of structure member, is also beneficial to the working power increasing motor.
Accompanying drawing explanation
Fig. 1: the structural representation of I. C. engine crankshaft device;
In figure: 1: cylinder block; 2: piston; 3: connecting rod; 4: bent axle.
Embodiment
Referring to accompanying drawing, provide embodiment of the present utility model, be used for being further described structure of the present utility model.
Embodiment 1
The I. C. engine crankshaft device of the present embodiment, comprise cylinder block 1, be placed in the piston 2 of cylinder block inside, bent axle 4 is connected with piston 2 by connecting rod 3, and bent axle 4 departs from piston 2 center line 20 degree, it is consistent that it departs from piston direction and bent axle direction of doing work, and namely deflects 20 degree clockwise.Bent axle departs from piston several angle, can be descending freely when piston does work, and greatly reduces the recoil force of piston and bent axle, the pressure that damper piston, connecting rod, bent axle three bear, and is beneficial to piston acting, increases the power of motor.
Embodiment 2
The I. C. engine crankshaft device of the present embodiment, its structure and embodiment 1 basically identical, difference is that bent axle 4 departs from piston 2 center line 22.5 degree clockwise, under this deviation angle, bent axle is not only easy for installation, also can most of pressure of bearing of damper piston, connecting rod, bent axle, increase the working power of motor.
Above embodiment is not exhaustive, and its protection domain is not limited to given embodiment.The angle departing from piston centreline as bent axle is 25 degree, 30 degree etc., and every all technological schemes achieved by thinking of the present utility model, all belong to protection domain of the present utility model.
Claims (2)
1. an I. C. engine crankshaft device, comprise cylinder block (1), be placed in the piston (2) of cylinder block inside, bent axle (4) is connected with piston (2) by connecting rod (3), it is characterized in that bent axle (4) departs from piston (2) center line 20-30 degree, it is consistent that it departs from piston direction and bent axle direction of doing work.
2. I. C. engine crankshaft device as claimed in claim 1, is characterized in that bent axle (4) departs from piston (2) center line 22.5 degree.
