Abstract
The invention discloses a square operating outer lane biserial cylindrical roller bearing for a fine punch, wherein, the outer lane (1) of the bearing has a rectangular thick-walled structure, an inner lane (4) has a circular structure, the width of the inner lane is larger than that of the outer lane, rollaway nests which are arranged on the inner lane and the outer lane are provided with two lines of cylindrical rollers (2) in parallel, and the two lines of cylindrical rollers are arranged in a pocket of a cage (6), one end of the cage is provided with an end closure (3) of the cage, the cage and the end closure are connected into a whole through a rivet (5) or a bolt. The outer lane of the bearing is designed into the square thick-walled structure, and the two lines of cylindrical rollers are arranged in the outer lane and the inner lane in parallel, so that larger impact load can be born, and special requirement of the fine punch can be fulfilled. The invention can finely fulfill the precision requirement of pressings of the press, and guarantee the convenience for assembling the bearing structure, while guaranteeing that the using of the bearing fulfills the requirement of impact load.
Description
Technical field
The invention belongs to technical field of bearings, specially refer to a kind of accurate punching machine with square work outer ring Biserial cylindrical roller bearing.
Background technique
Present domestic accurate punching machine the manufacturing and designing of still not having with square work outer ring Biserial cylindrical roller bearing.Close bearing such as back lining bearing, its structure are single row roller bearing, and the outer ring wall thickness is big, the surface is a cylinder, is applied on the rolling mill more, directly sheet material is rolled by the outer ring.The range request precision and accurate punching machine liquidates, the stability when guaranteeing punch ram requires bearing outer ring to be designed to square structure, and can bear greater impact load, and the design bearing that for this reason needs special construction is to satisfy the specific (special) requirements of accurate punching machine.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of accurate punching machine with square work outer ring Biserial cylindrical roller bearing, the outer ring of this bearing is designed to square thick-walled structure, is arranged side by side two line column rollers in the inside and outside circle, can bear greater impact load, to satisfy the specific (special) requirements of accurate punching machine.
For achieving the above object, the present invention adopts following technological scheme:
Described accurate punching machine is with square work outer ring Biserial cylindrical roller bearing, the outer ring of its bearing is square thick-walled structure, inner ring is a round structure, inner race width is greater than the outer ring width, in the set raceway of inside and outside circle, two line column rollers have been arranged side by side, two line column rollers place among the pocket hole of retainer, and dispose the retainer end cap at an end of retainer, are one by rivet with it riveted joint.
Described accurate punching machine is with square work outer ring Biserial cylindrical roller bearing, and its retainer and retainer end cap can also be connected as one it by screw.
Because adopt aforesaid technological scheme, the present invention has following superiority:
1) since punch press designing requirement bearing integral to bear bigger load bigger, guaranteeing under the limited condition of punch press demand space, the present invention uses at the assurance bearing and satisfies under the impact load requirement, and precision satisfies the required precision of punch ram spare simultaneously, guarantees that bearing structure is easy to assembly.
2) square work outer ring Biserial cylindrical roller bearing is applied on the special purpose machine tool of specific (special) requirements, can make lathe towards the develop rapidly of highi degree of accuracy direction, this class bearing succeed in developing the blank of having filled up domestic production, not only satisfy the demand of matched host machine unit, the exploitation and the production of seriation simultaneously maintain the leading position China technically, have also brought excellent economic to enterprise.
Description of drawings
Fig. 1 is a square work outer ring Biserial cylindrical roller bearing structural representation.
Among the figure: the 1-outer ring; The 2-cylindrical roller; 3-retainer end cap; The 4-inner ring; The 5-rivet; The 6-retainer.
Embodiment
As shown in Figure 1: accurate punching machine of the present invention is with square work outer ring Biserial cylindrical roller bearing, the outer ring of its bearing (1) is square thick-walled structure, inner ring (4) is a round structure, inner ring (4) width is greater than outer ring (1) width, in the set raceway of inside and outside circle, two line column rollers (2) have been arranged side by side, two line column rollers (2) place among the pocket hole of retainer (6), and dispose retainer end cap (3) at an end of retainer (6), are one by rivet (5) with it riveted joint.
Bearing outer ring of the present invention (1) side of being designed to body thick-walled structure, four cuboid surfaces when work, two direct bearing loads of adjacent surface wherein, two adjacent surfaces do not stress in addition, when two stressed adjacent surfaces wore and tore, available two adjacent surfaces that do not stress were replaced; In, outer ring width design is different, can bear bigger load to guarantee square work outer ring Biserial cylindrical roller bearing integral body, for this reason that two line column rollers (2) are placed side by side in interior, in the raceway of outer ring, simultaneously retainer end cap (3) and retainer (6) are placed from the bearing both ends of the surface respectively, two line column rollers (2) are placed among the pocket hole of retainer (6) just, and it is correct that retainer end cap (3) and retainer (6) position are cooperated, rivet (5) being penetrated retainer end cap (3) and retainer (6) goes up in the rivet hole of difference circumference uniform distribution again, with special tool rivet (5) is riveted tightly, finished assembly process.
In the structure of square work outer ring cylindrical bearing, outer ring (1) is workpiece, is used to bear big load, therefore consider that outer ring (1) wall thickness value is bigger in the design, its specific constructive form can variant is in various degree arranged, but basic structure be identical according to the difference of service condition; The bearing assembly method can adopt rivet (5) riveting dress, and the form that can also adopt screw to assemble is to guarantee that assembling is firm, rotation is flexible.
Because square work outer ring cylindrical bearing required precision height, so work in-process notes the discreteness of bearing tolerance; Because there be cooperating of inner ring (4) and cylindrical roller (2) assembly and outer ring (1) in bearing of the present invention, divide into groups in addition, assemble again, to satisfy bearing clearance and required precision so need carry out size to bearing parts.
Claims (2)
1. an accurate punching machine is with square work outer ring Biserial cylindrical roller bearing, it is characterized in that: the outer ring of its bearing (1) is square thick-walled structure, inner ring (4) is a round structure, inner ring (4) width is greater than outer ring (1) width, in the set raceway of inside and outside circle, two line column rollers (2) have been arranged side by side, two line column rollers (2) place among the pocket hole of retainer (6), and dispose retainer end cap (3) at an end of retainer (6), are one by rivet (5) with it riveted joint.
