Abstract
The utility model relates to a kind of disk bearing for armchair seat rotating mechanism, it is characterized in that: described disk bearing is formed by connecting by bearing outer ring and bearing inner race, annular groove is provided with between bearing outer ring and bearing inner race, be provided with ball retainer and steel ball in annular groove, bearing inner race is provided with steel ball shrouding.During use, under the cooperation of bearing outer ring and bearing inner race square annular groove, bearing outer ring and bearing inner race situation can carry out the variation of profile, mounting interface according to the actual requirements; Bearing outer ring, bearing inner race can carry out Choice and process technique according to the quantity of rotary seat, and machining, die casting, casting all can realize, and bearing outer ring, bearing inner race and steel ball, ball retainer carry out turning has joined.Thus obtain easy to manufacture, that less investment, cost of production are low, reliability is high, seat rotating force is little armchair seat rotating mechanism disk bearing.
Description
Technical field
The utility model relates to the technical field of disk bearing, specifically a kind of disk bearing for armchair seat rotating mechanism.
Background technique
In the rotating machinerys such as current train seat, automotive seat, often running into seat requirement ± 180 ° to rotate, in order to realize the running of seat rotational structure, ensureing seat carrying and resistance to capsizing, and rotating reliable, light, this just needs the bearing of certain bearing capacity.The bearing that current seat uses, mainly contains selfaligning ball bearing, self-aligning thrust roller bearing, thrust-bearing, friction type bearing, and its bearing uses heavy, and unstable, and supplementary equipment investment is large, and the shaking volume of seat is large.Also some enterprises are had directly from foreign procurement swivel bearing, but expensive, and do not meet in the rotational structure of China's seat system.Therefore the disk bearing designing the use of a set of seat special is extremely urgent.
Summary of the invention
The purpose of this utility model is the disk bearing for armchair seat rotating mechanism providing a kind of improvement, and it can overcome prior art middle (center) bearing and use heavy, and the some shortcomings of instability.
To achieve these goals, the technical solution of the utility model is: a kind of disk bearing for armchair seat rotating mechanism, it is characterized in that: described disk bearing is formed by connecting by bearing outer ring and bearing inner race, annular groove is provided with between bearing outer ring and bearing inner race, be provided with ball retainer and steel ball in annular groove, bearing inner race is provided with steel ball shrouding.
During use, disk bearing is designed to the new structure by bearing outer ring, bearing inner race, steel ball, ball retainer, steel ball shrouding five groups of part combination, and under ensureing the cooperation of bearing outer ring and bearing inner race square annular groove, bearing outer ring and bearing inner race situation can carry out the variation of profile, mounting interface according to the actual requirements; Bearing outer ring, bearing inner race can carry out Choice and process technique according to the quantity of rotary seat, and machining, die casting, casting all can realize, and bearing outer ring, bearing inner race and steel ball, ball retainer carry out turning has joined.Thus obtain easy to manufacture, that less investment, cost of production are low, reliability is high, seat rotating force is little armchair seat rotating mechanism disk bearing.
Accompanying drawing explanation
Fig. 1 is dispersed structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model one embodiment.
Fig. 3 is A-A sectional view in Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
The label of each accompanying drawing is expressed as follows: 1 bearing outer ring, 2 steel balls, 3 ball retainers, 4 bearing inner races, 5 steel ball shroudings, 6 screws, 7 steel ball mounting holes.
A kind of disk bearing for armchair seat rotating mechanism described in the utility model, its difference with the prior art is: described disk bearing is formed by connecting by bearing outer ring and bearing inner race, annular groove is provided with between bearing outer ring and bearing inner race, be provided with ball retainer and steel ball in annular groove, bearing inner race is provided with steel ball shrouding.
Bearing outer ring and bearing inner race are all rounded, an annular groove is formed between the outer side surface of bearing inner race and the inner side surface of bearing outer ring, the cross section of described annular groove is square, steel ball contacts respectively with the four sides inwall of annular groove, bearing inner race is provided with steel ball mounting hole, steel ball mounting hole is packaged with steel ball shrouding.Ball retainer is embedded with 4-10 steel ball, connect with bearing outer ring in bearing inner race, the outer side wall of bearing inner race and the madial wall of bearing outer ring are respectively equipped with a corresponding leg-of-mutton groove, two triangular grooves are spliced into a foursquare annular groove, connect with in annular groove in steel ball, bearing inner race is provided with steel ball mounting hole, and the position of steel ball is corresponding with the position of steel ball mounting hole.Steel ball mounting hole is provided with internal thread, and steel ball shrouding is provided with screw mounting hole, and steel ball shrouding is fixedly connected with bearing inner race by screw.
In enforcement, composition graphs 1-3 gives the organigram of the utility model armchair seat rotating mechanism disk bearing embodiment.Bearing outer ring 1 and bearing inner race 4 are assembled and are formed square annular groove, steel ball 2 and ball retainer 3 is studded with in described square annular groove, steel ball 2 and ball retainer 3 interval are arranged, four internal surface distributions of square annular groove are tangent with steel ball 2, namely the diameter of steel ball is identical with the square length of side of square annular groove, steel ball 2 and ball retainer 3 are put at bearing inner race 4 steel ball mounting hole place, after steel ball 2 and ball retainer 3 are covered with square annular groove, steel ball shrouding 5 is fixed by screw 6 and bearing inner race, thus puts into hole to steel ball and encapsulate.
During use, bearing outer ring is connected with pivoted frame, and bearing inner race is connected with underframe, but also can carry out contrary Placement, so just achieves the rotation of seat.
In seat system, use this disk bearing, effectively can alleviate seat-weight, improve the reliability of seat, reduce the rotating force of seat.In enforcement, under the cooperation ensureing bearing outer ring and bearing inner race square annular groove, bearing outer ring and bearing inner race situation can carry out the variation of profile, mounting interface according to the actual requirements; Bearing outer ring, bearing inner race can carry out Choice and process technique according to the quantity of rotary seat, and machining, die casting, casting all can realize, and bearing outer ring, bearing inner race and steel ball, ball retainer carry out turning has joined.Thus obtain easy to manufacture, that less investment, cost of production are low, reliability is high, seat rotating force is little armchair seat rotating mechanism disk bearing.
