Description
Technical field
The present invention relates to piston compressors to assemble parts technical field, especially a kind of drawing for crosshead component
Stretch convertible clamp device.
Background technique
It is often excessively connected using crosshead in the connection of connecting rod and piston rod in reciprocating compressor, piston rod
It is connect with connecting rod so that piston rod not will receive connecting rod bring lateral pressure by crosshead.The friction of piston and cylinder in this way is
It is the smallest.And crosshead and piston rod can only axially move, and can make full use of the volume of cylinder, control the side of lubricating oil
Method is fairly simple, increases the service efficiency of compressor.
Although there are many mode connected between piston rod and crosshead in reciprocating compressor, most of connection types
In be not that quality is bigger, exactly install it is more complicated, and in middle-size and small-size compressor crosshead quality size to pressure
The trim of contracting machine has a great impact.So installation is simple, the connection type of light weight at middle-size and small-size compressor first choice, and
Threaded connection just meets above-mentioned requirement.So the use of be most commonly used being exactly to be threadedly coupled in middle-size and small-size compressor.
Usually by piston rod, cross nut, one double nut lock of crosshead block composition in traditional threaded connection
Clamping system, and install a locked spacer additional between cross nut and crosshead block, by cross nut and crosshead
A possibility that mutually moving between ontology is preferably minimized, so that double nut fastening system is preferably locked, but double nut is locked
In it is higher to the torque requirement of nut check, locking torque is big, screw thread can be destroyed, stripped thread is caused to loosen, locking torque it is small can twist
Not tight nut will also result in loosening, and when breaking curved locked spacer and being tightly attached on cross nut by it, need using hammer
Son beats, and the tooth silk on nut is probably destroyed during beaing, to influence tightening for nut.
The working time of compressor is generally all special long, and reciprocal inertia force is also bigger, and double nut fastening system is in length
Will necessarily be loosened under the action of time reciprocal inertia force, a piece of locked spacer may prevent in a short time cross nut and
The mutual movement of crosshead block, but for a long time, under high-intensitive work, locked spacer itself can may be deformed also and lose work
With.Once generating to loosen between piston rod and crosshead and often generating great security risk, cylinder is hit, what generation can not balance
Torque accelerates the abrasion of piston and cylinder, the serious tragedy that may generate fatal crass.
Summary of the invention
The technical problem to be solved by the present invention is providing one kind in order to solve the problems, such as above-mentioned background technique and changing
