Abstract
Description
Technical Field
[0001] The utility model relates to an adjustable core bearing and belongs to the technical field of bearings. Background Art
[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other parts move relative to each other on the shaft, bearings can be used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Therefore, bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body and reduce the mechanical load friction coefficient of the equipment during transmission.
[0003] However, the existing bearings are fixed sleeve structures, in which the rolling elements and the inner and outer rings are not adjustable. When the rolling elements and the inner and outer rings of the bearing are used together, they will rub against each other, causing the rolling elements to wear, and the sleeve between the rolling elements and the inner and outer rings of the bearing to become loose, resulting in large shaking, causing the bearing to be unable to be used normally. In view of the above shortcomings, the utility model proposes an adjustable core bearing. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide an adjustable core bearing to solve the existing problems.
[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an adjustable core bearing, including an outer ring, a plurality of rolling bodies movably sleeved in the inner groove of the outer ring, a lower inner ring sleeved in the middle of the outer ring and abutting against the inner lower end of each rolling body, and the upper end of the lower inner ring is threadedly connected with an adjustable upper inner ring, and the lower end of the adjustable upper inner ring abuts against the inner upper end of each rolling body, and the upper end of the lower inner ring is threadedly connected with a locking ring for preventing the adjustable upper inner ring from loosening.
[0006] A further improvement is that a rolling element groove is provided in the middle of the inner side of the outer ring.
[0007] As a further improvement, the lower inner ring is formed by an upper sleeve and a lower sleeve as an integral unit, a rolling element lower clamping groove is provided on the circumference of the upper end of the lower sleeve, and an external thread is provided on the outer surface of the upper sleeve.
[0008] A further improvement is that the adjustable upper inner ring includes an upper inner ring body, a rolling body upper clamping groove opened on the circumference of the lower end of the upper inner ring body, and a first threaded opening opened in the middle of the upper inner ring body, and a plurality of adjustment sleeve openings are opened on the top surface of the upper inner ring body.
[0009] As a further improvement, the locking ring comprises a locking ring body, a second threaded opening opened in the middle of the locking ring body, and a plurality of locking sleeve openings are opened on the top surface of the locking ring body.
[0010] The beneficial effects of the utility model are:
[0011] The utility model provides an adjustable core bearing. Through the design of the adjustable core shaft composed of a lower inner ring, an adjustable upper inner ring and a locking ring and an outer ring and a rolling body inner ring, after the bearing has been used for a period of time, when a gap appears between the core shaft and the outer ring and the rolling body due to wear, causing the core shaft to shake and become unusable, the gap caused by wear and tear can be eliminated by adjusting and reducing the distance between the rolling body lower clamping groove on the lower inner ring and the rolling body upper clamping groove on the adjustable upper inner ring, so that the core shaft will not shake, can be used normally, and the service life of the bearing is extended.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] See also Figure 1-Figure 4 The utility model provides a technical scheme of an adjustable core bearing schematic diagram: it includes an outer ring 1, a plurality of rolling bodies 2 movably sleeved in the inner groove of the outer ring 1, a lower inner ring 3 sleeved in the middle of the outer ring 1 and abutting against the inner lower end of each rolling body 2, and the upper end of the lower inner ring 3 is threadedly connected with an adjustable upper inner ring 4, and the lower end of the adjustable upper inner ring 4 abuts against the inner upper end of each rolling body 2, and the upper end of the lower inner ring 3 is threadedly connected with a locking ring 5 for preventing the adjustable upper inner ring 4 from loosening, a rolling body slide groove 11 is opened in the middle of the inner side of the outer ring 1, and the lower inner ring 3 is integrally formed by an upper sleeve seat 31 and a lower sleeve seat 32 The lower sleeve 32 is provided with a rolling body lower clamping groove 33 on the circumference of the upper end, the upper sleeve 31 is provided with an external thread 34 on the outer surface, the adjusting upper inner ring 4 comprises an upper inner ring body 41, a rolling body upper clamping groove 42 provided on the circumference of the lower end of the upper inner ring body 41, a first threaded opening 43 provided in the middle of the upper inner ring body 41, a plurality of adjusting sleeve openings 44 are provided on the top surface of the upper inner ring body 41, the locking ring 5 comprises a locking ring body 51, a second threaded opening 52 provided in the middle of the locking ring body 51, and a plurality of locking sleeve openings 53 are provided on the top surface of the locking ring body 51.
[0018] Working principle:
[0019] The installation method is as follows: first, fit the outer ring 1 and the lower inner ring 3 together. At this time, a semi-open groove cavity that can accommodate the rolling body 2 will be formed between the rolling body groove 11 and the rolling body lower clamping groove 33. Then, each rolling body 2 is placed in the semi-open groove cavity. Then, the outer thread 34 cooperates with the thread of the first threaded opening 43 to make the rolling body upper clamping groove 42 on the upper inner ring body 41 abut against the inner upper end of each rolling body 2. In this way, the rolling body 2 can be stably abutted against each other through the rolling body groove 11, the rolling body lower clamping groove 33, and the rolling body upper clamping groove 42. Then, the upper inner ring body 41 is reinforced by the locking abutment of the locking ring 5 on the top surface of the upper inner ring body 41, so that when the upper inner ring body 41 is in use, the thread cooperation between the outer thread 34 and the first threaded opening 43 will not cause the reverse thread to loosen.
[0020] When the rolling body 2 and the rolling body groove 11, the rolling body lower clamping groove 33, and the rolling body upper clamping groove 42 are worn after being used for a period of time, a certain gap will appear, causing the core shaft formed by the lower inner ring 3 and the upper inner ring body 41 to shake. At this time, the locking ring 5 can be removed and then the upper inner ring body 41 can be locked to eliminate the gap, and then the locking ring 5 can be used to reinforce the upper inner ring body 41 to complete the adjustment of the bearing core shaft.
