Abstract

The invention discloses a double-column and multi-column cylinder roller bearing press-roll device which belongs to the technical field of bearing design. The double-column and multi-column cylinder roller bearing pressing roller device comprises a base plate (1), pressing rollers (2), a pressing rod (3), a small shaft (4), a bearing (5), a bearing pedestal (6), a spring hook (7), a small decorative pattern nut (8), a big decorative pattern nut (9), a positioning sleeve (10), a screw rod (11), a pressing roller bearing positioning block (12), a positioning rod pedestal (13), a positioning rod (14) and a spring (15). According to the pressing roller device provided by the invention, the quality problems such as roller path damage are avoided, under the loading effect, the roller path friction is reduced, and the rotation speed and the fatigue life of the bearing are improved.

Description

Biserial and multiple row roller bearing nip drum device

Technical field

The invention belongs to the design bearing technical field, be specifically related to a kind of biserial and multiple row roller bearing nip drum device.

Background technique

At present, the producer of domestic production biserial and the medium-and-large-sized roller bearing of multiple row in assembling during roller, utilizes iron hammer that all rollers of every cover bearing is pounded in the raceway basically, causes the serious gouge of raceway, influences quality of product, has reduced the fatigue life of bearing.

Summary of the invention

The purpose of this invention is to provide a kind of biserial and multiple row roller bearing nip drum device, it has avoided quality problems such as raceway gouge, under loading, reduces raceway frictional force, has improved the rotational speed and the fatigue life of bearing.

In order to achieve the above object, technological scheme of the present invention is following:

Biserial and multiple row roller bearing nip drum device comprise base plate, nip drum, depression bar, little axle, bearing, bearing support, carbine, little decorative pattern nut, big-pattern nut, setting sleeve, leading screw, nip drum bearing positioning block, location pole socket, positioning rod and spring, and leading screw is welded on the base plate; Bearing support is fixed on the setting sleeve, and setting sleeve is fastened on the leading screw through two big-pattern nuts, and spring one end hangs on the carbine; Be fixed on the little decorative pattern nut; Little decorative pattern nut and leading screw flexibly connect, and the spring the other end hangs over the medium position of depression bar, and little axle cooperates with bearing and is set on the bearing support; Depression bar is fixed on the little axle; Nip drum is fixed on the depression bar through screw, and depression bar moves up and down through bearing support and setting sleeve, and nip drum bearing positioning block is fixed on the positioning rod through screw; Positioning arm cover is on the pole socket of location, and the location pole socket is fixed on the base plate by screw.

The invention has the beneficial effects as follows: nip drum device of the present invention has been avoided quality problems such as raceway gouge, under loading, reduces raceway frictional force, has improved the rotational speed and the fatigue life of bearing.

Embodiment

Below in conjunction with accompanying drawing the present invention is explained further details.

Shown in Fig. 1-4, biserial of the present invention and multiple row roller bearing nip drum device mainly are made up of base plate 1, nip drum 2, depression bar 3, little axle 4, bearing 5, bearing support 6, carbine 7, little decorative pattern nut 8, big-pattern nut 9, setting sleeve 10, leading screw 11, nip drum bearing positioning block 12, location pole socket 13, positioning rod 14 and spring 15 etc.

Leading screw 11 is welded on the base plate 1 in the nip drum device of the present invention; Bearing support 6 is fixed on the setting sleeve 10, and setting sleeve 10 leans on two big-pattern nuts 9 to be fastened on the leading screw, and spring 15 1 ends hang on the carbine 7; Be fixed on the primary nut 8; Nut 8 can move up and down on leading screw, and the spring the other end hangs over the depression bar medium position, and is as shown in Figure 4.Little axle 4 cooperates with bearing 5 and is set on the bearing support 6, and depression bar 3 is fixed on little 4, and can rotate up and down.Nip drum 2 is fixed on the depression bar 3 through screw, can move horizontally adjusting, and depression bar 3 can move up and down with bearing support 6 and setting sleeve 10, and the height that moves depends on the nip drum bearing height.Nip drum bearing positioning block 12 is fixed on the positioning rod 14 through screw, and positioning rod 14 is enclosed within on the positioning seat 13, and positioning seat 13 is fixed on the base plate 1 by screw, and positioning rod 14 can move forward and backward according to nip drum bearing diameter size, comes radial location.

The outer assembly of nip drum bearing is moved on the base plate 1, spent from the horizontal by 45 according to 14, two bars of its diameter adjustment positioning rod; Make it be radially positioned in the center correct position, and then the adjustment depression bar 3 suitably highly get final product, realize through adjusting two big-pattern nuts 9; At last nip drum 2 is adjusted on the outer internal diameter ball-loading hole of bearing outer ring and locates, the right hand lifts depression bar 3 during work, and left hand is placed on the ball-loading hole place with roller; Roller nature and horizontal tilt one angle, as shown in Figure 1, the right hand slightly downwards firmly roller be pressed into raceway; Like Fig. 2, shown in Figure 3, this moment, depression bar 3 resetted by spring 15, and the right hand is helped gently and got final product; To just press the roller at place, goal mouth to rotate a pocket hole site to the left or to the right together with retainer with left hand then, left hand is put second roller in place, goal mouth, circulation above-mentioned steps again; The rest may be inferred, can accomplish the assembling of all rollers.

Nip drum device of the present invention has been avoided quality problems such as raceway gouge, under loading, reduces raceway frictional force, has improved the rotational speed and the fatigue life of bearing.
