Description
Technical field
The utility model relates to piston rod part, particularly the piston rod part of refrigerator, refrigerator compressor.
Background technique
The compressor of refrigerator and refrigerator is through the bent axle drivening rod, and the piston that connecting rod drives in the cylinder body again moves back and forth, and realizes compression effectiveness; Owing to drive through bent axle, do oscillating motion in the time of the connecting rod displacement.Refrigerator in the prior art, the piston rod part of refrigerator compressor such as Fig. 1, shown in Figure 2, bent axle d and connecting rod c outer end pivot connect, connecting rod c the inner is connected with piston a through bearing pin b, during motion, connecting rod c drives piston a moves back and forth at in-plane reciprocally swinging one angle beta vertical with bearing pin except being the axle center with bearing pin b, connecting rod c does not allow in other any direction a bit swing is arranged, otherwise the piston motion meeting is obstructed and is stuck even, this just requires the angle α of bent axle and connecting rod to remain absolute right angle, and both angles are protected absolute right angle all the time under motion state, so very high to the requirement on machining accuracy of associated workpiece, difficulty of processing is very big; If the workpiece processing precision reduces a little, allow connecting rod other direction outside the in-plane vertical that small sway is arranged with bearing pin, then to make between piston and cylinder body to have certain interval, but will have air to pass in and out like this from gap location, reduce the compressor effect.
Summary of the invention
The utility model will solve refrigerator, the refrigerator compressor connecting bar is connected existing workpiece processing difficulty height through bearing pin with piston, the problem that piston motion is obstructed easily, refrigerator of the present utility model, refrigerator compressor crank shaft link assembly are provided for this reason, this assembly can reduce the requirement of bent axle and connecting rod angle precision, make associated workpiece processing relatively easy, and piston does not exist and is obstructed or stuck problem.
For addressing the above problem, its special way of the technical solution adopted in the utility model is that described bent axle partly is made of bent axle body and the spheroid that is eccentric in bent axle body axle center that is connected in bent axle body one end, described connecting rod has con-rod only, con-rod only one end has the ball of containing hemizonid, contain the concave spherical surface part that the ball hemizonid is provided with diametric(al) one side, be provided with and contain the symmetry that the ball hemizonid combines and contain the ball hemizonid with described, symmetry contains the concave spherical surface part that the ball hemizonid is provided with the diametric(al) opposite side, describedly contain concave spherical surface part that ball hemizonid and symmetry contain the concave spherical surface part of described diametric(al) one side under the ball hemizonid amalgamation coupled condition and diametric(al) opposite side and combine and constitute the diametric(al) land portions, the spheroid part of described bent axle contains ball hemizonid and symmetry to contain the described diametric(al) land portions of ball hemizonid amalgamation formation identical mutually with described.
The ball hemizonid that contains described in the utility model with the optimal way that symmetry contains the amalgamation of ball hemizonid is, the described place, both sides that contains ball hemizonid symmetry has screw respectively, the place, both sides that described symmetry contains ball hemizonid symmetry has through hole respectively, described two groups of screws, through hole are corresponding one by one, pass respectively in corresponding two groups of through holes and the screw with two bolts, make to contain the ball hemizonid and contain the mutual amalgamation of ball hemizonid with symmetry and be connected.Before amalgamation connects mutually, the described spheroid of bent axle in the utility model is partly inserted the described concave spherical surface part that ball hemizonid, symmetry contain the ball hemizonid that contains, after amalgamation connects, bent axle is connected combination with connecting rod, so, except the swing of bent axle drivening rod produces the reciprocal translation connecting rod the other end, bent axle and connecting rod be rotation in any direction each other.
The utility model is because connecting rod one end has the ball of containing hemizonid, this hemizonid is provided with the concave spherical surface part, be provided with can with contain symmetry that the ball hemizonid combines and contain the ball hemizonid and which is provided with the concave spherical surface part, bent axle is provided with eccentric spheroid part, this spheroid part can be coincide mutually with the land portions that described two concave spherical surfaces partly are combined to form, so bent axle combines with connecting rod, both are rotation in any direction each other, thereby eliminated in the prior art because bent axle/connecting rod causes piston motion to be obstructed even stuck drawback when having non-absolute right angle, guaranteed refrigerator, the refrigerator compressor all the time can proper functioning; The utility model has solved prior art simultaneously and has caused the big and high problem of processing cost of difficulty of processing because of associated components requirement on machining accuracy height.
