Abstract
A kind of piston compressor big end tile structure, it includes first axle tile fragment, second bearing shell block and threeth bearing shell block of the end face in 120 ° of arcuate structures, end face is connected to form the bearing shell body of circle with end face between first axle tile fragment, the second bearing shell block and the 3rd bearing shell block, bearing shell body is fixed on gonnecting rod body by alignment pin, and oilhole corresponding with connecting rod oil circuit is provided with bearing shell body.The utility model provides a kind of stress balance, and abrasion is small, the piston compressor big end tile structure of service life length.
Description
Technical field
A kind of bearing bush structure is the utility model is related to, a kind of specific piston compressor big end tile structure.
Background technology
The moving component of piston compressor is made up of bent axle, connecting rod, crosshead, piston rod, piston, when external impetus band
When dynamic crankshaft rotates, bent axle drivening rod moves in a circle around crankshaft axis together, bent axle and the connecting rod being fixed on connecting rod
Major part watt directly contacts generation friction, due to there is circulating lubricating oil to play lubrication, anti-attrition, cooling mechanism effect therebetween, therefore
It will not dry grind and burn out between big end watt and bent axle；When crankshaft high-speed rotation drivening rod rotary motion simultaneously, connecting rod
Major part watt is easily extruded by bent axle rotary motion, and particularly rod fracture causes connecting rod unbalance stress, or connecting rod and bent axle
Connecting rod unbalance stress is also resulted in when sideshake is excessive, connecting rod unbalance stress causes big end watt local pressure imbalance,
Big end watt is caused abrasion, rupture easily occur, it is therefore necessary to shut down changed in time；Big end watt pole is changed in maintenance
Its is time-consuming, big to Influence of production, again it cannot be guaranteed that equipment runs well for a long time.
The content of the invention
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, and a kind of stress provided
Balance, abrasion is small, the piston compressor big end tile structure of service life length.
What the purpose of utility model was realized in：
A kind of piston compressor big end tile structure, it include end face in 120 ° of arcuate structures first axle tile fragment,
Second bearing shell block and the 3rd bearing shell block, end face and end face phase between first axle tile fragment, the second bearing shell block and the 3rd bearing shell block
Circular bearing shell body is even formed, bearing shell body is fixed on gonnecting rod body by alignment pin, is provided with bearing shell body and connecting rod
Oilhole corresponding to oil circuit.
Above-mentioned first axle tile fragment, the second bearing shell block and the 3rd bearing shell block are almag bearing shell block.
Using said structure, bearing bush structure is improved to three pieces by traditional two pieces of 180 ° of arcuate structure bearing shell block combining structures
120 ° of arcuate structure bearing shell block combining structures, with bent axle contact area it is constant in the case of, by reduce tile fragment radially
Loading angle, it can disperse the extruding force of bearing shell is avoided bearing shell local pressure excessive and causes wear extent big when bent axle rotates；
Particularly bearing shell unbalance stress when, each bearing shell block load angle only has 120 °, and stress is lighter, avoids traditional 180 ° of arcuate structures
Bearing shell block is squeezed the risk of easy fracture, therefore balances bearing shell stress, the service life for alleviating abrasion, extending bearing shell,
Reduce frequency of maintenance, in turn ensure that equipment is continuously run for a long time.
Each bearing shell block is almag material global formation, and need to inlay anti-attrition on the contact surface without traditional steel back tile fragment closes
The complicated technology of layer gold, therefore be simple to manufacture, it is easy to change.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of piston compressor big end tile structure as shown in Figure 1, it includes end face in the of 120 ° of arcuate structures
One bearing shell block 1-1, the second bearing shell block 1-2 and the 3rd bearing shell block 1-3, first axle tile fragment 1-1, the second bearing shell block 1-2 and
End face is connected to form the bearing shell body of circle with end face between three bearing shell block 1-3, and bearing shell body is fixed on connecting rod by alignment pin 2
On body 3, oilhole 4 corresponding with connecting rod oil circuit is provided with bearing shell body.
The first axle tile fragment 1-1, the second bearing shell block 1-2 and the 3rd bearing shell block 1-3 are almag bearing shell block.
Using said structure, when bent axle rotary motion, drivening rod moves in a circle around crankshaft axis together, bent axle
Directly contact generation friction with the big end watt that is fixed on connecting rod, the utility model by do not change contacted with bent axle by
In the case of power area, by reducing each tile fragment radial force angle, to disperse to avoid the extruding force of bearing shell when bent axle rotates
Bearing shell local pressure is excessive and causes wear extent big；Particularly bearing shell unbalance stress when, each bearing shell block load angle only has 120 °,
Stress is lighter, avoids traditional 180 ° of arcuate structure bearing shell blocks and is squeezed the risk of easy fracture, therefore balances bearing shell stress, subtracts
Light abrasion, the service life for extending bearing shell, reduce frequency of maintenance, in turn ensure that equipment is continuously run for a long time.
