Individual link assembly, a link assembly drive reciprocating motion of the pistons by crosshead part, and adjacent two row crank throw is into 180 degree
Point-blank, i.e., there is no spacing in arrangement, the motion of its two row piston, each suite axle connects between the axis of two row pistons
Inertia mass at left and right sides of linkage is identical, so that the inertia force of each group of crankshaft connecting rod system reaches balance, but
In this case the inertia mass at left and right sides of crankshaft connecting rod system is adjusted anyway, and its caused moment of inertia is to obtain
Balance is arrived, and bearing-free support among the crank throw of bent axle, shafting amount of deflection are big；If can not balancing inertia torque, compressor
It will be run in the state of unstable, cause vibration, can caused bearing bush abrasion serious when ill-conditioned, even result in parts
Corrupted etc..Therefore, it is necessary to change the arrangement form of crankshaft connecting rod system to solve problem above.
The content of the invention
In order to solve the above-mentioned technical problem, it is an object of the invention to provide a kind of balanced type crank gear, eliminate
Moment of inertia, makes that vertical compressor group is with small vibration, operates steadily, and has been more suitable for shock and vibration, has tilted and the Special Ring such as wave
Border.
The present invention adopts the following technical scheme that：A kind of balanced type crank gear, including six groups of crankshaft connecting rod systems,
Every group of crankshaft connecting rod system includes a row crank throw, piston rod, the crosshead of piston and installation on the piston rod, technical points
It is：Six groups of crankshaft connecting rod systems use following arrangement form, from anti-drive end towards drive end in terms of, when compressor up time
When pin rotates, six row crank throw phase angles are successively by 0 degree, 240 degree, 120 degree, 120 degree, 240 degree, 0 degree of arrangement, when compressor inverse
When pin rotates, six row crank throw phase angles are arranged by 0 degree, 120 degree, 240 degree, 240 degree, 120 degree, 0 degree, between adjacent two row crank throw
Bearing supporting is provided with, six pistons include big piston and valve piston, and six groups of crankshaft connecting rod systems connect including big piston bent axle
Linkage and valve piston crankshaft connecting rod system, counterweight cushion block group is installed in the crosshead of valve piston crankshaft connecting rod system, directly
It is equal to six groups of crankshaft connecting rod system quality；Babbit layer is sprayed on two external cylindrical surfaces of crosshead.
Piston in the crankshaft connecting rod system is using the piston or cylinder backup seal formula with cylinder labyrinth sealing type
Piston.
Babbit layer is sprayed on described two external cylindrical surfaces of crosshead, positioned at the babbit layer length and width side
It is used to the crosshead pin being connected with connecting rod one end be installed to the key seat in centre position.
It is an advantage of the invention that：Unit is by dynamic balancing, level and tilts the high precision tests such as mechanical running test, ensures
Product quality and high reliability and product efficiency height, small volume, floor space is small, noise is low, with small vibration, margin of safety is big, peace
Complete reliable, cycle of operation length, integral level is in domestically leading status, and reaches international like product advanced level；It is completely flat
Weighing apparatus type compressor is applied to have shock and vibration, inclination to wave, and has the particular surroundings such as salt fog, ocean high humility, can be widely applied to
In ship and ocean engineering environment, market prospects are considerable.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Reference is as follows：1st, bent axle 2, link assembly 3, crosshead 4, crank 5, counterweight cushion block group 6, piston rod
7th, piston 8, crank throw.
Embodiment
As shown in figure 1, a kind of balanced type crank gear that present example provides, every group of crankshaft connecting rod system include
One row crank throw 8, piston rod 6, piston 7 and the crosshead 3 on piston rod 6, six groups of crankshaft connecting rod systems are using such as
Under arrangement form, from anti-drive end towards drive end in terms of, when compressor turns clockwise, the phase angle of six row crank throw 8 is successively
By 0 degree, 240 degree, 120 degree, 120 degree, 240 degree, 0 degree of arrangement, when compressor rotate counterclockwise, the phase angle of six row crank throw 8 presses 0
Spend, 120 degree, 240 degree, 240 degree, 120 degree, 0 degree of arrangement, bearing supporting, six pistons 7 are provided between adjacent two row crank throw 8
Include big piston and valve piston, six groups of crankshaft connecting rod systems include big piston crankshaft connecting rod mechanism and valve piston crankshaft-link rod machine
Structure, counterweight cushion block group 5 is installed in the crosshead 3 of valve piston crankshaft connecting rod system, until six groups of crankshaft connecting rod system quality
It is equal；Babbit layer is sprayed on 3 two external cylindrical surfaces of crosshead.
Piston 7 in the crankshaft connecting rod system is using the piston or cylinder backup seal formula with cylinder labyrinth sealing type
Piston.
Babbit layer is sprayed on described 3 two external cylindrical surfaces of crosshead, positioned at the babbit layer length and width
The key seat in direction centre position is used to install the crosshead pin being connected with connecting rod one end.
The present invention operation principle be：Above-mentioned device and conventional symmetric balanced type transmission of crankshaft as seen in Figure 1
Device has significant difference, and two row crank throws 8 of conventional symmetric balanced type crank mechanism are arranged into 180 degree, and bent in the present invention
