Abstract
The utility model discloses a coupling type slewing bearing, which comprises an oil cup, an outer ring, a steel ball, an isolation block, an inner ring, a sealing strip, a plug and a taper pin; the inner ring is additionally provided with a shaft structure and a key groove and is connected with an upper hub of equipment through the key groove; the outer ring is connected with the lower square flange through a bolt. The utility model discloses a shaft coupling formula slewing bearing, inner circle axle construction can be directly be connected with wheel hub when the installation, can neglect the influence of mounting platform to the inner circle installation to the solution produces the influence of installation deformation because of the mounting platform plane degree is poor.
Description
Technical Field
The utility model relates to and slewing bearing technical field especially relates to a shaft coupling formula slewing bearing.
Background
The coupling type slewing bearing is a modification of a single-row ball type slewing bearing specified in the existing JB/T2300-2018 standard and the JB/T10839-2008 standard. Some equipment can only use a small-sized back-up support due to limited structure, and if the inner ring is fixed by using a bolt, the problem of insufficient bolt bearing exists. Therefore, in order to solve the problem of installation and fixation of the inner ring, a shaft structure is added on the original basis, and the installation problem is solved through a shaft fixing mode.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a shaft coupling formula slewing bearing has solved the fixed problem of slewing bearing inner circle among the prior art.
The technical scheme of the utility model is that: a kind of shaft coupling type slewing bearing, including oil cup, outer lane, steel ball, spacer block, inner race, sealing strip, jam, taper pin; the inner ring is additionally provided with a shaft structure and a key groove and is connected with an upper hub of equipment through the key groove; the outer ring is connected with the lower square flange through a bolt.
Furthermore, a plugging hole is formed in the outer ring, a steel ball and a spacer block are installed in the inner roller way ring between the inner ring and the outer ring through the plugging hole, and then a plug and a taper pin are assembled.
Further, the lower edge opening part of the inner ring surface of the outer ring and the lower edge opening part of the outer ring surface of the inner ring are provided with ring grooves, and sealing strips are arranged in the ring grooves.
Furthermore, the oil cup is arranged on the outer ring surface of the outer ring, and lubricating grease is filled into the inner ring through the oil nozzle.
Compared with the prior art, the utility model has the advantages that:
the utility model discloses a shaft coupling formula slewing bearing, inner circle axle construction can be directly be connected with wheel hub when the installation, can neglect the influence of mounting platform to the inner circle installation to the solution produces the influence of installation deformation because of the mounting platform plane degree is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the coupling type slewing bearing comprises an oil cup 1, an outer ring 2, a steel ball 3, an isolation block 4, an inner ring 5, a sealing strip 6, a plug 7 and a taper pin 8, wherein the inner ring is additionally provided with a shaft structure design, so that the problem of installation and fixation of the inner ring is solved.
A shaft coupling formula slewing bearing of above-mentioned structure, the accessible inner circle axle construction is fixed, has solved because of the structure is limited, can't fix through the bolt problem.
In the above embodiment, the lower bead part of the inner ring surface of the outer ring 2 and the lower bead part of the outer ring surface of the inner ring 5 are provided with ring grooves, and sealing strips 6 are arranged in the ring grooves to prevent rainwater and dust from entering the raceway; during installation, the steel ball 3 and the spacer 4 are arranged in the raceway through the plugging hole of the outer ring 2, then the plug 7 and the taper pin 8 are assembled, finally the outer ring of the slewing bearing is connected with the lower flange through a bolt, and the inner ring is connected with the upper hub of the equipment through the key groove 9.
In the above embodiment, the oil cup 1 is provided on the outer circumferential surface of the outer ring 2, and grease is filled into the inner ring 5 through the oil nipple to maintain the raceway.
In conclusion, the coupling type reloading support comprises an oil cup, an outer ring, a steel ball, an isolation block, an inner raceway ring, a sealing strip, a plug and a taper pin structure, wherein the inner raceway ring and a shaft are integrated, and when the inner ring is fixed, the inner ring can be directly fixed through the shaft, so that the problem of insufficient bearing of a bolt is ignored.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
