Description
Technical field
The utility model relates to a kind of parts of compressor, and more particularly, it relates to a kind of cross shaped joint for compressor.
Background technique
Crosshead is as one of big-and-middle-sized compressor main motion parts, and its effect is the conversion realizing motion mode, by the rotary motion of crank mechanism, is changed, become straight line motion, to promote the functional movement of piston by the motion of connecting rod and crosshead.Due to crosshead, in this movement process, stressing conditions is than connecting rod, piston rod all relative complex, and it and slideway constitute a pair kinematic pair, so be proposed very high requirement to the structure, quality, material, manufacturing process etc. of crosshead.
The main forms of compressor crosshead lubrication trouble is that crosshead temperature significantly raises, and then emerge black smoke or spark, and sends the stink of lubricant oil burning, and crosshead surface alloy obviously melts or comes off, and friction surface blackout even causes seizure.
The reason of fault is due to crosshead and slideway quality of fit is not normal and due to the not any place stored for lubricant oil of inner chamber of crosshead, make the amount of the lubricant oil in crosshead all fewer, and then force them to make large fricting movement, friction portion and lubricant oil outwards dispel the heat not in time, and the main purpose of lubrication is to reduce contact between solid by lubricating film as far as possible, thus minimizing friction and wear, and by lubricant oil, frictional heat is transmitted to the external world, thus suppression temperature rise, if crosshead and slideway quality of fit not normal, destroy lubricant film, crosshead then can be caused to damage, and crosshead and the not normal Resolving probiems of slideway quality of fit get up to need very large cost and it is more difficult to realize, so problem can be solved to adding in the inner chamber of crosshead into lubricant oil, so current used a kind of cross shaped joint for compressor has certain room for improvement.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of cross shaped joint for compressor, can add more lubricant oil to make to reduce friction and wear, the situation causing crosshead to damage to avoid occurring destroying lubricant film.
For achieving the above object, the utility model provides following technological scheme: a kind of cross shaped joint for compressor, comprise body, the madial wall of described body is provided with the holding tank stored for lubricant oil, described holding tank comprises the first translot, the second translot, the 3rd translot and vertical slot, described first translot, the second translot and spaced set parallel successively with the 3rd translot, described vertical slot is communicated with the first translot, the second translot, the 3rd translot successively, and described vertical slot is positioned at the middle part of the madial wall of body.
Preferably, the identical length etc. of the length of described first translot, the length of the second translot and the 3rd translot.
Preferably, described body comprises longitudinal register seat and located lateral seat, and the joint of described longitudinal register seat and located lateral seat is provided with ring stiffener.
Preferably, reinforcement gusset is also provided with between described longitudinal register seat and located lateral seat.
Preferably, described reinforcement gusset is modification of right-angled triangle plate, and two right angle sides of described modification of right-angled triangle plate are connected with longitudinal register seat, located lateral seat one respectively.
Preferably, described reinforcement gusset is symmetricly set in the both sides of longitudinal register seat, and the reinforcement gusset of every side is equipped with two.
The utility model hinge structure is compared to be had: by arranging holding tank on the madial wall of cross shaped joint, can add more lubricant oil to make to reduce friction and wear, the situation causing crosshead to damage to avoid occurring destroying lubricant film.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation one of the present utility model;
Fig. 2 is structural representation two of the present utility model;
Fig. 3 is the partial sectional view in A-A portion in Fig. 2.
In figure: 1, body; 2, holding tank; 3, the first translot; 4, the second translot; 5, the 3rd translot; 6, vertical slot; 7, longitudinal register seat; 8, located lateral seat; 9, ring stiffener; 10, gusset is strengthened.
Embodiment
Shown in Fig. 3, embodiment is described further.
A kind of cross shaped joint for compressor disclosed in the utility model, comprise body 1, body 1 comprises longitudinal register seat 7 and located lateral seat 8, longitudinal register seat 7 and located lateral seat 8 are in being wholely set, longitudinal register seat 7 is provided with ring stiffener 9 with the joint of located lateral seat 8, make longitudinal register seat 7 higher with the structural strength of located lateral seat 8 joint, avoid the situation occurring that longitudinal register seat 7 ruptures with the joint of located lateral seat 8, also be provided with between longitudinal register seat 7 and located lateral seat 8 simultaneously and strengthen gusset 10, because leg-of-mutton structure is one of most stable structure, therefore reinforcement gusset 10 is set to modification of right-angled triangle plate, simultaneously two right angle sides of modification of right-angled triangle plate respectively with longitudinal register seat 7, located lateral seat 8 one connects, strengthen the both sides that gusset 10 is symmetricly set in longitudinal register seat 7, and the reinforcement gusset 10 of every side is equipped with two, make the structural strength improving longitudinal register seat 7 and located lateral seat 8, whole cross shaped joint is avoided to cause due to structural strength problem damaging.
