The most important transmission part is the motor transmission. The motor has many uses, especially when used on the pump body, it is necessary to regularly inspect the bearings at the connection between the motor and the pump body to avoid damage to the pump body bearings.

[0003] The bearing on the pump body will use a longer roller bearing as a whole, and a corresponding retainer will be used on the bearing to space the bearing rollers. The existing bearing retainer only has the function of spacing the rollers. The lubricating oil inside the bearing diffuses slowly, and a separate structural seal is required on the outside. The rollers on the retainer cannot be disassembled, making it difficult to inspect and maintain the bearing rollers. Utility Model Content

[0004] The disclosed embodiment relates to a retaining frame structure for pump bearings. During maintenance and overhaul, the outer ring of the bearing is directly removed, and lubricating oil is added to the retaining assembly and the ball shaft on the opposite side retaining ring. The inner cylinder hole of the retaining assembly allows the lubricating oil to flow between each other, thereby increasing the lubrication between the ball shafts. When the ball shaft is damaged, the guide assembly at the outer end of the side retaining ring is directly inserted into the push rod column, and the push rod column is allowed to press against the clamping assembly to allow the clamping assembly to detach from the retaining frame at the outer layer. At this time, the retaining assembly can be separated to achieve rapid replacement of the ball shaft, and the retaining assembly can be installed and reused through the clamping assembly.

[0005] According to a first aspect of the present disclosure, a retaining frame structure for a pump bearing is provided, specifically comprising: a bearing outer ring; the bearing outer ring is directly fixed to the pump body, a side retaining ring is installed at the inner end of the bearing outer ring, a retaining assembly is arranged on the side retaining ring, a ball shaft is carried between the retaining assemblies, a clamping assembly is installed at the contact position of the retaining assembly, a bearing inner ring is arranged at the inner end position of the ball shaft at the retaining assembly, an inner cylinder hole is arranged on the inner wall of the retaining assembly, a guide assembly is arranged on the outer wall of the side retaining ring, and a push rod column is inserted and installed at the guide assembly.

[0008] In at least some embodiments, the inner retaining frames are arranged to be spaced apart from each other, the ball shafts can be rotatably mounted at the intervals between the inner retaining frames, and two groups of inner cylinder holes are arranged on the outer clamping frame.

[0009] In at least some embodiments, the clamping groove of the clamping assembly is arranged on the retaining assembly, a clamping block is clamped and installed at the clamping groove of the external clamping frame, a spring is installed at the mounting point of the clamping block and the clamping groove, and a chamfer is arranged at the outer end of the clamping block.

[0010] In at least some embodiments, the guide hole of the guide assembly is arranged on the side retaining ring, the outer end of the guide hole is arranged as a conical structure, the inner end of the guide hole is connected to the guide groove, and the guide groove is directly connected to the position of the inner frame.

[0011] The utility model provides a retainer structure for pump bearings, which has the following beneficial effects:

[0012] The side retaining ring of the utility model is arranged to be clamped and fixed by the clamping assembly of the retaining assembly, so that the retaining assembly can stably retain the ball shaft and allow the ball shaft to rotate stably on the bearing. The retaining assembly is arranged at the position of the ball shaft with an inner cylinder hole, and the inner cylinder hole can allow the lubricating oil to circulate between each other, so as to achieve better lubrication of the ball shaft. When the ball shaft is inspected and repaired, if the ball shaft is damaged, the ball shaft cannot be directly removed and replaced, so the retaining assemblies are installed on the side retaining rings at the two positions, and the retaining assemblies are arranged to be clamped and contacted with each other, so that the side retaining rings can be clamped and installed by the retaining assemblies, and the contact positions of the retaining assemblies are clamped and fixed by the clamping assembly. When the side retaining rings need to be separated and disassembled, the push rod column is directly inserted from the position of the guide assembly at the side retaining ring, and the push rod column is pushed in to reset the clamping assembly, so that the retaining assembly of the side retaining ring can be separated, thereby realizing the disassembly of the ball shaft, and the outer edge of each group of side retaining rings is provided with a contact ring, which increases the sealing of the contact ring to the side retaining ring, thereby increasing the protection of the ball shaft.

[0013] In addition, the side retaining ring is configured as a structure fixed to the retaining assembly, so that the side retaining ring can be directly installed on the outer end of the inner ring of the bearing, and the contact ring is installed in the outer groove along the inner and outer edges of the side retaining ring. Concave and convex grooves are provided on the wall of the outer groove, so that the contact ring is more stable when installed in the outer groove, and the contact ring is stably in contact with the inner ring of the bearing, so that the contact ring assists and the side retaining ring to achieve better support.

[0014] In addition, the two sets of side retaining rings are respectively provided with an outer clamping frame and an inner retaining frame, and the outer clamping frame and the inner retaining frame can be installed correspondingly by clamping, and the inner retaining frame and the outer clamping frame are both provided with protruding blocks, so that the protruding blocks can contact with the inner ring and the outer ring of the bearing, so as to provide auxiliary support when the retaining assembly and the side retaining ring rotate, making the rotation of the ball shaft more stable.

[0015] In addition, the outer card frames are arranged to be spaced apart from each other so that the ball shafts can be stably rotatably installed between the outer card frames, thereby forming an auxiliary retaining effect of the retaining assembly on the ball shafts. The two groups of inner cylinder holes arranged on the outer card frames allow the ball shafts between each other to be connected to lubricating oil, thereby forming a better lubrication effect for the ball shafts between each other.

[0016] In addition, in order to enable the inner frame and the outer clamping frame of the retaining component to be clamped and fixed to each other, a clamping groove is directly set at the retaining component, and a clamping block is installed at the clamping groove through a spring clamping. At this time, when the outer end of the outer clamping frame is clamped and installed with the inner frame, the inner frame is pressed against the chamfered position of the clamping block, and the inner frame presses the clamping block down until the inner frame and the outer clamping frame are in place, and then the clamping block pops up to fix the position of the inner frame and the outer clamping frame.

[0017] In addition, when in use, directly insert the guide hole at the outer end of the side retaining ring with the inner frame retaining into the push rod column. The guide hole with a conical structure allows the push rod column to be inserted better. After the push rod column is pushed in, it will be directly guided to the chamfer of the clamping block, allowing the clamping block to be reset, so that the clamping block can be separated from the clamping groove of the inner frame retaining, thereby realizing the disassembly and separation of the inner frame retaining and the outer clamping frame.
