Abstract
The utility model provides a connecting rod joint bearing, have connecting rod, the threaded connection of external screw thread including one end or both ends in internal thread rod end joint bearing on connecting rod one end or both ends, internal thread rod end joint bearing is for when it receives predetermined external force to act on with thereby the connecting rod takes place plastic deformation and prevents when connecting rod joint bearing connects the motion on external equipment internal thread rod end joint bearing with the connecting rod takes place not hard up internal thread rod end joint bearing, and internal thread rod end joint bearing is difficult for taking place not hard up with the connecting rod when connecting rod joint bearing moves on external equipment, and shock resistance is strong, and is not fragile, long service life need not frequent maintenance, is favorable to the use.
Description
Technical Field
The utility model relates to a joint bearing technical field, concretely relates to connecting rod joint bearing.
Background
The joint bearing is a spherical sliding bearing, mainly consists of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, and can bear larger load. The bearing shaft is generally used for swinging motion with low speed and low-speed rotation, can also perform tilting motion within a certain angle range, and can still normally work when the concentricity of the bearing shaft and the shaft shell hole is large. The rod end joint bearing is a joint bearing with or arranged at a rod end. The rod end joint bearing is applied to corners of automobiles, medical equipment and looms.
The conventional connecting rod joint bearing comprises a connecting rod with external threads at one end or two ends and an internal thread rod end joint bearing in threaded connection with one end or two ends of the connecting rod.
When the connecting rod knuckle bearing is connected to external equipment to move, the internal thread rod end knuckle bearing and the connecting rod are easy to loosen, the shock resistance is weak, the connecting rod knuckle bearing is easy to damage, the service life is short, frequent maintenance and repair are needed, and the use is not facilitated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a connecting rod joint bearing to prior art's defect and not enough.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a connecting rod joint bearing comprises a connecting rod with an external thread at one end or two ends, and an internal thread rod end joint bearing in threaded connection with one end or two ends of the connecting rod, wherein the internal thread rod end joint bearing is used for preventing the internal thread rod end joint bearing from loosening with the connecting rod when the internal thread rod end joint bearing is connected to external equipment to move under the action of preset external force.
The further improvement is that: the internally threaded rod end knuckle bearing may be threadably coupled to the connecting rod at a predetermined location when not subjected to a predetermined external force.
After the technical scheme is adopted, the utility model discloses beneficial effect does: one end or both ends have the connecting rod of external screw thread, threaded connection is in the internal thread rod end joint bearing on connecting rod one end or both ends, thereby the internal thread rod end joint bearing bears predetermined exogenic action and takes place plastic deformation with the connecting rod and prevent that internal thread rod end joint bearing and connecting rod from taking place not hard up when connecting rod joint bearing connects to move on external equipment, internal thread rod end joint bearing is difficult for taking place not hard up with the connecting rod when connecting rod joint bearing moves on external equipment, impact resistance is strong, and is not fragile, long service life, need not frequent maintenance, the maintenance, be favorable to using.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of the inner thread rod end joint shaft of the present invention after bearing a predetermined external force and the connecting rod is plastically deformed.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 2, the technical solution adopted by the present embodiment is:
the utility model provides a connecting rod joint bearing, includes that one end or both ends have connecting rod 2, threaded connection of external screw thread 1 in internal thread rod end joint bearing 3 on 2 one end of connecting rod or both ends, internal thread rod end joint bearing 3 is for when it receives predetermined exogenic action with connecting rod 2 takes place plastic deformation thereby when connecting rod joint bearing connects the motion on the external equipment prevent internal thread rod end joint bearing 3 with connecting rod 2 takes place not hard up internal thread rod end joint bearing 3.
The internally threaded rod end joint bearing 3 is threadably attached to the connecting rod 2 at a predetermined position when not subjected to a predetermined external force.
The utility model discloses a theory of operation: one end or both ends have connecting rod 2 of external screw thread 1, threaded connection is in connecting rod one end or the internal thread rod end joint bearing 3 on both ends, thereby internal thread rod end joint bearing 3 receives predetermined exogenic action to take place plastic deformation with connecting rod 2 and prevents that internal thread rod end joint bearing 3 and connecting rod 2 from taking place not hard up when connecting rod joint bearing connects to move on the external equipment, internal thread rod end joint bearing 3 is difficult for taking place not hard up with connecting rod 2 when connecting rod joint bearing moves on the external equipment, impact resistance is strong, it is not fragile, long service life, need not frequent maintenance, the maintenance, be favorable to using.
The inner thread rod end joint bearing 3 can be acted by a riveting press machine, so that the inner thread rod end joint bearing and the connecting rod 2 are subjected to plastic deformation.
The foregoing shows and describes the basic principles and features of the present invention and their advantages, which should be understood by those skilled in the art, and it is not limited by the foregoing embodiments, but only by the illustrations presented in the foregoing embodiments and illustrations.
Claims (2)
1. The utility model provides a connecting rod joint bearing, includes that one end or both ends have connecting rod, the threaded connection of external screw thread in internal thread rod end joint bearing on connecting rod one end or both ends, its characterized in that: the internal thread rod end joint bearing is an internal thread rod end joint bearing which is plastically deformed with the connecting rod when the internal thread rod end joint bearing is acted by a preset external force so as to prevent the internal thread rod end joint bearing and the connecting rod from loosening when the connecting rod joint bearing is connected to external equipment to move.
2. The connecting rod spherical plain bearing according to claim 1, wherein: the internally threaded rod end knuckle bearing may be threadably coupled to the connecting rod at a predetermined location when not subjected to a predetermined external force.
