Abstract
The invention discloses a low-noise split-type slewing bearing, comprising an outer upper ring, an outer lower ring, a middle outer ring, an inner upper ring, an inner lower ring, a middle inner ring, a rubber cushion, a rolling body and a retainer. The low-noise split-type slewing bearing is characterized in that a rolling way is arranged at the contact end surfaces of the middle inner ring and the middle outer ring; rubber cushions are additionally arranged on the end surfaces of the middle inner ring and the middle outer ring; a small slewing bearing formed by the middle outer ring and the middle inner ring is arranged above the outer lower ring and the inner lower ring; the outer upper ring and the outer lower ring, as well as the inner upper ring and the inner lower ring are mounted and matched with each other; and the outer upper ring and the outer lower ring, as well as the inner upper ring and the inner lower ring are fastened by coupling screws. The low-noise split-type slewing bearing is capable of achieving the purposes of small starting torque, running at a high speed and low noise.
Description
Technical field
The invention belongs to a kind of pivoting support, be specifically related to a kind of pivoting support that is applicable to high rotating speed, low noise occasion.
Background technique
What the pivoting support of using on the present medical CT machine mainly bore is radial load, and the thrust load of bearing is very little, and starting torque is little, and needs to realize running up, and need overcome the big problem of noise.Traditional pivoting support can't satisfy the requirement of low moment, high rotating speed, low noise.
Summary of the invention
The purpose of this invention is to provide a kind of starting torque little, run up and pivoting support that noise is low.
For realizing above-mentioned purpose; The present invention adopts following technological scheme: the split type pivoting support of low noise comprises outer Shang Quan, Wai Xiaquan, middle outer ring, interior Shang Quan, Nei Xiaquan, middle inner ring, rubber pad, rolling element, retainer; Its main feature is: middle inner ring and middle outer ring contact jaw face are respectively equipped with raceway, add rubber pad at middle inner ring, each end face of middle outer ring; In the little pivoting support that forms of outer ring and middle inner ring by being placed on Wai Xiaquan and the interior circle down, outer Shang Quan and Wai Xiaquan, interior Shang Quan and interior circle down installation respectively cooperate, and with joint bolt with outer Shang Quan and Wai Xiaquan, interior Shang Quan and interior under enclose fastening.
Raceway adopts 30 ° of wrapping angles also to adopt ceramic ball as rolling element, with satisfy starting torque little, run up.
The present invention is rational in infrastructure, and bearing capacity is better, is mainly used in and can realizes on the medical CT machine that starting torque is little, runs up, the purpose of low noise.For the expansion of pivoting support application provide maybe, can well be used in the occasion that low noises such as medical device industry require.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, Wai Xiaquan, 2, the outer circle of going up, 3, rubber pad, 4, middle outer ring, 5, ceramic ball, 6, retainer, 7, the interior circle of going up, 8, middle inner ring, 9, taper pin, 10, stop up, 11, Nei Xiaquan.
Embodiment
Shown in Figure 1, the split type pivoting support of low noise comprises outer circle 2, outer circle 1 down, middle outer ring 4, interior circle 7, interior circle 11, middle inner ring 8, ceramic ball 5, retainer 6, the rubber pad 3 down gone up gone up.In the raceway of 30 ° of wrapping angles that middle outer ring 4 and middle inner ring 8 form retainer 6 and ceramic ball 5 are installed successively; Outer ring 4 also relatively rotates with middle inner ring 8 mutual supports in the pivoting support; In the pivoting support that forms of outer ring and middle inner ring less owing to diameter, so starting torque is little, can realize running up.Be provided with rubber pad 3 at middle inner ring 4, middle outer ring 8 each end face; Middle outer ring 4 is down enclosed 11 on by enclosing 1 outside being placed in down with interior with the little pivoting support that middle inner ring 8 forms; Will be outward go up circle 2 and enclose 1 installation that matches down with outer; And with joint bolt will be outward go up circle 2, outer circle 1 down is fastening, interior go up circle 7 and interior 11 installation methods of circle down with go up outward, the outer installation of circle down.The transmission of noise in raceway when rubber pad 3 can reduce to vibrate and effectively weaken pivoting support and rotates, thus realize the effect of low noise.
Claims (3)
1. the split type pivoting support of low noise comprises outer Shang Quan, Wai Xiaquan, middle outer ring, interior Shang Quan, Nei Xiaquan, middle inner ring, rubber pad, rolling element, retainer; Inner ring and middle outer ring contact jaw face are respectively equipped with raceway in it is characterized in that, add rubber pad at middle inner ring, each end face of middle outer ring; In the little pivoting support that forms of outer ring and middle inner ring by being placed on Wai Xiaquan and the interior circle down, outer Shang Quan and Wai Xiaquan, interior Shang Quan and interior circle down installation respectively cooperate, and with joint bolt with outer Shang Quan and Wai Xiaquan, interior Shang Quan and interior under enclose fastening.
2. the split type pivoting support of a kind of low noise according to claim 1 is characterized in that adopting ceramic ball as rolling element.
