Abstract
The utility model provides a seat rotation mechanism, relates to seat connection structure's improvement. The utility model discloses a high some shortcomings are crossed to the too big cost of rotary thrust in overcoming prior art, provide a modified train seat rotation mechanism. The utility model discloses a pivot is inserted on the revolving rack, and the bearing frame outside is fixed on the chassis internal diameter, and the bearing frame inboard is fixed on joint bearing's outer tile, and joint bearing's interior tile cover is in the pivot, correspond chassis one side at the revolving rack and install the revolving rack draw runner, install the chassis draw runner on the chassis of corresponding revolving rack draw runner, the spherical washer cover is in the pivot, and the inner circle card of spherical washer has the round nut at the pivot lower extreme through threaded connection on the bearing housing, installs braking packing ring and wave spring between round nut and the spherical washer outer lane, and the curvature card of braking packing ring is on the round nut. The utility model discloses simple structure, installation convenient to use adopts joint bearing and spherical washer cooperation to play the aligning effect, plays jointly with wave spring and offsets revolving rack and chassis manufacture error and installation error. Make the whole manufacture error of seat obtain reducing, can guarantee that the seat can rotate smoothly simultaneously.
Description
Technical field
The utility model relates to the improvement of Seat connection structure.
Background technology
Along with the development of China's economic construction and the progress of science and technology, the railway of China achieves great-leap-forward development, extensive railway construction efficiently advances, a collection of main construction is constructed and put into operation in succession, technology innovation obtains a collection of great achievement newly, high speed railway construction and international cooperation make important progress, and passenger and freight transportation creates the highest again.
In order to adapt to the new situations of Leap-forward Development of Railway, traditional in-vehicle device facility cannot meet the needs of development of the situation, in-vehicle device facility is carried out to the transformation of hommization, to improve the traveling comfort of passenger vehicle, practicality, the attractive in appearance of safety and environment inside car become the problem of pendulum in track passenger train installation and the supporting producer of parts.
As everyone knows, rotary seat on current domestic motor-car, its spinfunction is all realize seat spinfunction by the rotation of rotating disk or bearing, no matter is rotating disk or bearing, after running a period of time, mechanism all can produce wearing and tearing, its stability reduces, and along with the lengthening of passenger vehicle time of run, the parts wear of rotation portion continues to increase, cause the reliability and stability of rotary seat constantly to decline, the cost of existing rotary seat is also very high simultaneously.In addition because this type of rotary seat needs enough spaces to meet its radius of rotation.
Summary of the invention
The purpose of this utility model overcomes the some shortcomings such as the excessive high cost of rotary thrust in prior art, provides a kind of train seat swing type mechanism of improvement.
Rotating shaft of the present utility model is inserted on pivoted frame, is fixed on underframe internal diameter outside bearing seat, is fixed on outer watt of oscillating bearing inside bearing seat, and the Neva of oscillating bearing is enclosed within rotating shaft; In pivoted frame corresponding underframe side, pivoted frame draw runner is installed, the underframe of corresponding pivoted frame draw runner is provided with underframe draw runner; Spherical washer is enclosed within rotating shaft, and the inner ring of spherical washer is stuck on bearing carrier ring, has been threaded connection circular nut in rotating shaft lower end, is provided with drag washer and wavy spring between circular nut and spherical washer outer ring, and the sweep of drag washer is stuck on circular nut.
The utility model structure is simple, easy to install, adopts oscillating bearing to coordinate with spherical washer and plays aligning effect, jointly plays offset pivoted frame and underframe manufacturing errors and installation error with wavy spring.The overall manufacturing errors of seat is reduced, seat energy smooth rotation can be ensured simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Rotating shaft 1 of the present utility model is inserted on pivoted frame 5, be fixed on underframe 4 internal diameter outside bearing seat 3, be fixed on outer watt of oscillating bearing 2 inside bearing seat 3, the Neva of oscillating bearing 2 is enclosed within rotating shaft 1, so form underframe 4, bearing seat 3, outer watt of oscillating bearing 2 maintain static, and outer watt of oscillating bearing 2 is rotated along with rotating shaft 1; In pivoted frame 5 corresponding underframe 4 side, pivoted frame draw runner 7 is installed, the underframe 4 of corresponding pivoted frame draw runner 7 is provided with underframe draw runner 6; Spherical washer 8 is enclosed within rotating shaft 1, the inner ring of spherical washer 8 is stuck on bearing carrier ring 3, be threaded connection circular nut 9 in rotating shaft 1 lower end, be provided with drag washer 10 and wavy spring 11 between circular nut 9 and spherical washer 8 outer ring, the sweep of drag washer 10 is stuck on circular nut 9.
The utility model seat is made up of underframe and pivoted frame part, radial location is done by rotating shaft between pivoted frame and underframe, pivoted frame and underframe contact site have draw runner to do axial support respectively, oscillating bearing is installed in rotating shaft, installation shaft bearing on underframe, penetrates bearing seat by the rotating shaft with bearing, and lower end mounting spherical packing ring is also locked with circular nut, spherical washer and oscillating bearing one work, and play aligning effect.During use, the utility model adopts oscillating bearing, and cost is low, safe and reliable, can balance out the Mismachining tolerance of underframe and pivoted frame, makes seat energy ease rotation.
The bearing seat 3 that the utility model mainly comprises rotating shaft 1, is arranged on the oscillating bearing 2 in rotating shaft and is welded on underframe, underframe 4 and pivoted frame 5 install underframe draw runner 6 pivoted frame draw runner 7 respectively, and rotating shaft bottom installs set of spherical membrane packing ring 8, circular nut 9, drag washer 10, wavy spring 11 respectively.
In force, pivoted frame and underframe do radial location by rotating shaft, and the oscillating bearing in rotating shaft and set of spherical membrane packing ring play aligning effect, balance out the installation error of pivoted frame and underframe, there is wavy spring below spherical washer during installation, ensure that seat axially has minor adjustments.
