Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and particularly relates to a slewing support bearing. Background Art

[0002] The slewing bearing is a new type of mechanical component. It consists of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time. The slewing bearing is also called a turntable bearing. Some people also call it: a rotating bearing or a slewing bearing. The slewing bearing is widely used in real industry and is called the "joint of the machine". It is an important transmission component required for machines that need to make relative rotational motion between two objects and withstand axial force, radial force, and overturning moment at the same time.

[0003] The known authorized invention (publication number: CN110805613A) discloses a slewing support bearing with noise reduction function, including a bearing inner ring and a bearing outer ring, an annular outer plate is provided on both the upper and lower sides of the bearing outer ring, the side walls of the two annular outer plates facing each other are provided with a first annular groove, the upper and lower side walls of the bearing inner ring are provided with a second annular groove, a plurality of balls are provided in the two first annular grooves, and the plurality of balls cooperate with the second annular grooves, the side walls of the two annular outer plates facing each other are provided with a plurality of positioning grooves, bolts are provided in the plurality of positioning grooves, and the upper and lower side walls of the bearing outer ring are symmetrically provided with a plurality of threaded grooves matching the bolts. The slewing support bearing with noise reduction function can facilitate the installation of the bearing and has good stability, thereby reducing the noise during the operation of the bearing and facilitating people's use;

[0004] When the device is in use, although the annular outer plate and the bearing outer ring can be clamped together, and the positioning groove and the thread groove are set correspondingly, and then the bolts are provided, the bolts and the thread grooves can be threaded together by turning the bolts, thereby ensuring the stability of the fixation between the annular outer plate and the bearing outer ring, but the device is connected by multiple bolts and professional tools are required, which not only increases the complexity and time cost of installation, but is also relatively inconvenient during disassembly or adjustment, thereby reducing work efficiency. For this reason, a slewing support bearing is proposed. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a slewing support bearing. By setting up a new locking mechanism, rapid disassembly and assembly between the annular outer plate and the bearing outer ring is achieved. This improvement not only eliminates the need for professional tools, making the operation easier, but also significantly improves the efficiency of assembly and reduces time costs.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A slewing support bearing comprises a bearing outer ring and a bearing inner ring. A bearing inner ring is arranged on the inner side of the bearing outer ring. A plurality of connectors are connected to both sides of the bearing outer ring. Locking grooves are arranged on the connectors. An annular outer plate is arranged on both sides of the bearing outer ring. A cavity is arranged on one side of the annular outer plate. A locking mechanism corresponding to the number and position of the connectors is arranged in the cavity. The locking mechanism comprises a fixed rod and a locking head. The fixed rod is connected to an inner wall of one side of the cavity. A locking head is provided on a sliding sleeve of the fixed rod. The locking head is clamped in the corresponding locking groove. A spring for driving the locking head to pop out is provided on the fixed rod. A pull rod is connected to one side of the lock head. A fixed pulley is rotatably connected to the inner wall of one side of the cavity. A flexible steel rope is connected to one side of the pull rod. The end of the flexible steel rope passes around the corresponding fixed pulley and passes through the annular outer plate to be connected to the pull ring. The pull ring is slidably connected to the outer side of the annular outer plate.

[0008] The spring sleeve is arranged on the fixing rod.

[0009] Pull the pull ring, and the pull ring drives the corresponding pull rod to move through the flexible steel rope, and the pull rod drives the corresponding lock head to slide on the fixed rod. The lock head compresses the corresponding spring during the movement, so that the two lock heads on the same annular outer plate move towards each other, and then are clamped on the corresponding connecting head through the groove on the annular outer plate. When the annular outer plate contacts one side of the bearing outer ring, the pulling force on the pull ring is released, and the spring in the compressed state is reset. Under the action of the spring's own elastic force, the spring drives the corresponding lock head to be clamped with the lock groove, thereby fixing the annular outer plate and the bearing outer ring. According to the above steps, the other annular outer plate can be fixed. When disassembling, just pull the pull ring. The operation is simple and convenient.

[0010] One side of the annular outer plate is provided with grooves corresponding to the positions and numbers of the lock heads, the inner walls of the grooves are in active contact with the outer sides of the corresponding connectors, and the lock heads can be inserted into the grooves.

[0011] One side of the pull ring is connected to a limiting rod, and at least two limiting rods are provided. A strip-shaped limiting hole is opened on the inner wall of the other side of the cavity. The inner wall of the limiting hole is slidably connected to the outer side of the corresponding limiting rod. The limiting rod and the limiting hole limit the moving distance of the pull ring to protect the internal structure.

[0012] A through hole is provided on the inner wall of one side of the groove, and the inner wall of the through hole is slidably connected with the outer side of the corresponding lock head. The provision of the through hole ensures that the lock head is not affected when moving, and guides the lock head at the same time.

[0013] A slide groove is provided on the lock head, and the lock head is slidably connected with the corresponding fixed rod through the slide groove, and the fixed rod plays a role of positioning and guiding.

[0014] The inner wall on one side of the groove limits the lock head to prevent it from slipping out of the cavity.

[0015] The beneficial effects of the utility model are:

[0016] 1) By setting up a new type of locking mechanism, the quick disassembly and assembly between the annular outer plate and the bearing outer ring is realized. This improvement not only eliminates the need for professional tools, making the operation easier, but also significantly improves the efficiency of assembly and reduces time costs.

[0017] 2) In actual application, workers can complete the assembly and disassembly of bearings through simple operations without using any tools. This improvement not only simplifies the work process and reduces labor intensity, but also makes the maintenance and replacement of bearings more convenient, greatly improving work efficiency.

[0018] 3) In addition, the locking mechanism in this patented technology is cleverly designed and compact in structure, which not only does not increase the overall volume and weight of the bearing, but also ensures the stability and reliability of the connection. During the operation of the bearing, the locking mechanism can effectively prevent the loosening and falling off between the annular outer plate and the outer ring of the bearing, ensuring the normal operation and service life of the bearing.
