Description
Technical field
The present invention relates to piston machine, particularly a kind of piston machine mechanism and piston motion implementation method.
Background technique
Piston machine is widely used in motor and reciprocating pump field, and its core drive mechanism is the connecting rod that generally uses at present.
Connecting rod is because simple in structure, technology maturation, thus obtained using widely.But it has following shortcoming: piston that is connected with connecting rod or crosshead straight reciprocating motion part receive bigger radial force, and the frictional loss that in its sliding process, produces is bigger, and mechanical efficiency is lower; When being used for multi-cylinder, owing to need to press the straight line layout, mechanism takes up room bigger.
U.S. Pat 7004121B2 in 2007 " the piston layout of piston machine and piston controlling method " has proposed a kind of piston circle distribution, cam-actuated six cylinder piston machines; This structure and connecting rod relatively have advantages such as volume is little, in light weight, pulsatile impact is little.But the cam difficulty of processing in this method is big, mechanism is complicated, and the roller in the mechanism receives radial force bigger, and guide mechanism can produce big frictional loss.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide that a kind of volume is little, in light weight, efficient is high, simple in structure, easy to manufacture, piston machine mechanism and the piston motion implementation method of being convenient to industrialization.
In order to achieve the above object, the present invention realizes through following technological scheme: it comprises inclined shaft, rolling bearing, wobble-plate, wobble-plate constraint moving part, quiet of wobble-plate constraint, two ball pivot connecting rod, straight reciprocating motion part, straight reciprocating motion attaching means, piston, cylinder sleeve and matrix.Said inclined shaft is a transmission shaft, and rolling bearing is installed on the inclined shaft, and bearing connects and the constraint wobble-plate; Be connected with wobble-plate constraint moving part on the wobble-plate, quiet of wobble-plate constraint is installed on the matrix, and the motion of wobble-plate constraint moving part receives quiet constraint of wobble-plate constraint; N two ball pivot connecting rod one ends are connected on the wobble-plate; Two ball pivot connecting rod the other ends are connected with the straight reciprocating motion part, and the straight reciprocating motion attaching means is installed on the matrix, and the motion of straight reciprocating motion part is retrained by the straight reciprocating motion attaching means; Cylinder sleeve is installed on the matrix, and piston moves reciprocatingly in cylinder sleeve; Said inclined shaft is the acutangulate axle of an end face and rotation axis, and rolling bearing is installed on the end face; Said wobble-plate constraint moving part and being dynamically connected of quiet of wobble-plate constraint have been limited wobble-plate and have been retrained moving part and rotate around the inclined shaft spin axis; Said pair of ball pivot connecting rod is that two ends are rod members of ball pivot, is uniformly distributed along the circumference on wobble-plate, and its quantity is N >=3; Said straight reciprocating motion part is connected in the ball pivot seat of two ball pivot connecting rod one ends, and the straight reciprocating motion attaching means is installed on the matrix, and being dynamically connected of straight reciprocating motion attaching means and straight reciprocating motion part realized the straight reciprocating motion of straight reciprocating motion part; Said piston is connected in the straight reciprocating motion part, and piston and cylinder sleeve also can unite two into one with straight reciprocating motion part and straight reciprocating motion attaching means respectively.
