Abstract

The utility model discloses a disc bearing for a rotating mechanism and aims to provide the disc bearing for the rotating mechanism, which has the advantages of simplicity in manufacture, investment conservation and low production cost. The disc bearing comprises a bearing outer ring, a bearing inner ring and steel balls; the bearing inner ring comprises a bearing inner upper ring and a bearing inner lower ring; the bearing inner upper ring is arranged in the bearing outer ring; the bearing inner lower ring is axially and fixedly mooted on the bearing inner upper ring through bolts; the bearing inner lower ring and the bearing inner upper ring form a square ring groove; the steel balls are inlayed in the square ring groove; the four inner surfaces of the square ring groove are tangent to the steel balls respectively; an upper flange is fixedly mounted on the upper plane of the bearing inner lower ring through countersunk screws; and a lower flange is fixedly mounted on the lower plane of the bearing inner lower ring through countersunk screws. The disc bearing for the rotating mechanism is suitable for being mounted and used on special transport trailers, mining machinery, construction machinery and certain non-standard special equipment.

Description

Rotating machinery is used disk bearing

Technical field

The utility model relates to a kind of disk bearing, especially relates to a kind of rotating machinery and uses disk bearing.

Background technique

On special use transportation trailer, mining machinery, engineering machinery and some nonstandard special devices; Can often run into major diameter size rotating machinery; In order to realize the rotating machinery running; Guarantee that it carries and anti-ly covers ability just, and turn to reliably, light that this just needs the disk bearing of certain bearing capacity.The disk bearing that uses at present adopts the Internal and external cycle two-part construction, along the circumferential direction studs with steel ball in the middle of the Internal and external cycle, and inner ring, outer ring adopt the steel plate punch forming process to process, and needs the processing of design mold and adopts the special device assembling, and equipment investment is big.Some enterprises are also arranged directly from foreign procurement, cost an arm and a leg.Especially little for lots of production, the equipment of need major diameter size disk bearing, its disk bearing manufacture difficulty is bigger.Therefore there is the problem that the manufacturing process difficulty is big, investment is big, cost of production is high.

The model utility content

The purpose of the utility model is to overcome deficiency of the prior art, provides a kind of easy to manufacture, less investment and the low rotating machinery of cost of production to use disk bearing.

For realizing above-mentioned purpose, the utility model adopts following technical proposals: the rotating machinery of the utility model is used disk bearing, comprises bearing outer ring, bearing inner race and steel ball.Said bearing inner race is formed by going up in the bearing to enclose down in circle and the bearing; Going up circle in the bearing is arranged in the bearing outer ring; Enclose down in the said bearing and enclose through on bolt axis is in being packed in bearing; And with bearing outer ring and bearing in go up circle and constitute square annular groove, in said square annular groove, stud with steel ball, four internal surfaces of square annular groove are tangent with steel ball respectively; The plane is fixed with through sunk screw and connects dish on enclosing in said bearing, and the lower plane of circle connects dish under being fixed with through sunk screw down in said bearing.

As the further improvement of the utility model, in said bearing on the circle inboard radial symmetric two lubricating cups are set.

After adopting technique scheme; The rotating machinery that the utility model provides with the beneficial effect that disk bearing has is: since with disk bearing be designed to by go up in bearing outer ring, the bearing circle, bearing Nei Xiaquan, on connect dish, connect and coil five structures that disk body combines down; The all available machine tool processing of these parts; Can accomplish assembling with general tool, be convenient to make major diameter size disk bearing, can satisfy different batch production requirement.Thereby obtain easy to manufacture, less investment and the low effect of cost of production.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

In Fig. 1, Fig. 2 and Fig. 3, provided the organigram of the utility model rotating machinery with the disk bearing embodiment, comprise bearing outer ring 8, bearing inner race and steel ball 6.Said bearing inner race is made up of circle 4 under going up in circle 2 and the bearing in the bearing; Going up circle 2 in the bearing is arranged in the bearing outer ring 8; Circle 4 axially is packed in through bolt 5 and goes up on the circle 2 in the bearing under in the said bearing; And with bearing outer ring 8 and bearing in go up circle 2 and constitute square annular groove, in said square annular groove, stud with steel ball 6, four internal surfaces of square annular groove are tangent with steel ball 6 respectively; On in said bearing circle 2 on the plane be fixed with through sunk screw 3 and connect dish 1, down the lower plane of circle 4 is fixed with through sunk screw 7 to connect down and coils 9 in said bearing.

As the improvement mode of execution of the utility model, can be as shown in Fig. 1, Fig. 4 and Fig. 5, in said bearing on the inboard radial symmetric of circle 2 two lubricating cups 10 are set.Like this can be by the order of classes or grades at school requirement through two lubricating cups 10 to the rotating machinery lubricant oil of annotating in disk bearing, guarantee that it is wear-resistant, rotate flexibly.

During use, rotating machinery connects dish 9 with disk bearing following and is packed on the rotating member lower rotary table, rotating member top rotary table pedestal be installed in disk bearing on connect on the dish 1.So just can realize the vertical rotation of mechanism.

On special use transportation trailer, mining machinery, engineering machinery and some nonstandard special devices; Especially lots of production is little; Under the situation of major diameter size rotating machinery; Be fit to use the rotating machinery of the utility model and use disk bearing, can effectively bring into play easy to manufacture, less investment and the low advantage of cost of production.
