A compact type bowed roller bearing seat of a double-roller type temper mill comprises a shaft sleeve, a bearing and an end cover. The bearing and the end cover are arranged outside the shaft sleeve. The compact type bowed roller bearing seat is characterized in that annular grooves are formed in the side faces of the two ends of the shaft sleeve, the two ends of the shaft sleeve are provided with adjustment nuts in a sleeved mode respectively, and the adjustment nuts comprise an inner nut and an outer nut which are in threaded fit. One side of the inner nut abuts against the bearing, and the outer side of the outer nut is limited by an annular ring with the lower portion being embedded in the annular groove. With reference to the two annular grooves in the side faces of the end cover in the axial direction, the first annular groove corresponds to the outer nuts, a sealing ring is arranged between the first annular groove and the outer nut, and the outer portion of the sealing ring is fixed by an annular cover plate; the annular cover plate is embedded in the second annular groove in the side face of the end cover, the annular cover plate is connected with the end cover through a bolt, an annular flange is arranged on the inner side face of the annular cover plate, and the end face of the annular flange abuts against the sealing ring. The compact type bowed roller bearing seat changes the force bearing point and bearing capacity, and the series problems of low work efficiency of roller bending force and work roller play due to breakage of the bent roller bearing seat bolt are solved.
Description
Technical field:
The utility model relates to bearing block, particularly double-roller type planisher compact roller bearing block.
Background technology
Stainless smooth common employing double-roller type planisher, for rectification plate shape, must arrange roll-bending device.Because main bearing seat and roller bearing block all are arranged on working roll, so locational space is less.Usually design is: as shown in Figure 1, bearing 10 and end cap 20, cover plate 30, seal 40 are arranged on axle sleeve 50, and during dismounting, connecting shaft cover 50 is pulled down together, and axle sleeve 50 and working roll 60 adopt bolt 70 to be fixed, consider shearing force, generally also bolt collar 80 can be set.Axially and the radially bending roller force that makes working roll bear due to this design all is delivered on axle sleeve, makes bolt 70 be very easy to fracture, usually on new working roll after smooth two volumes of machine bolt just start fracture, the consequence of generation is:
When 1, smooth, bending roller force can't normally be used, and is generally and avoids the quick play of working roll only to dare to use 35% bending roller force;
2, after bolt fracture, owing to being matched in clearance between working roll and axle sleeve, cause working roll and axle sleeve contact surface abrasion serious, repeatedly the reconditioning contact-making surface has affected the life-span of working roll;
3,, after bolt fracture, cause the serious brinelling power transmission shaft of working roll play shaft coupling;
4, planisher working roll play when work; to cause latch distortion and bolt looseness; resistance while after the latch distortion, having increased the top working roll lifting; one side can make top working roll lifting inclination stuck, can make on the other hand roll line adjusting device lifting moment become large and jump electricity or safety coupling disconnection shutdown.When serious, can cause the roll line adjusting device stuck.
Summary of the invention
The purpose of this utility model, by a kind of double-roller type planisher compact roller bearing block of design, changes stress point and bearing capacity, the series of problems such as the bending roller force inefficiency that the fracture of solution roller bearing block bolt causes, working roll play.
For achieving the above object, the technical solution of the utility model is:
Double-roller type planisher compact roller bearing block, comprise axle sleeve and outer bearing and end cap thereof; It is characterized in that, side, described axle sleeve two ends has annular groove, and, these two ends are sheathed adjusting nut respectively, this adjusting nut comprises the inside and outside nut of threaded engagement, and inner nut one side is against bearing, and the snap ring that the outer nut outside is embedded at annular groove by bottom is spacing; Described end cap side is two cannelures vertically, and wherein, the corresponding outer nut of the first cannelure, establish a sealing ring between cannelure and outer nut; Sealing ring is outer to be fixed by an annular cover plate; This annular cover plate is embedded at the second cannelure of end cap side, and by bolt, it is connected with end cap; The annular cover plate medial surface is established annular flange flange, and this annular flange flange end face is against sealing ring.
Further, also establish protective cover, be positioned at the outer distolateral of described axle sleeve, protective cover adopts cover plate to connect being bolted on cover plate of end cap.
Described sealing ring is lip-type packing.
The inner nut of described adjusting nut is provided with for the axle sleeve bolt, coordinating the locating slot of locating.
Again, the outer nut of described adjusting nut is provided with the groove that screws of gap adjustment when loading and unloading.
In addition, and snap ring described in the utility model adopts one half snap rings, by connecting pin, connects.
The beneficial effects of the utility model:
1. adopt the design of adjusting nut and snap ring location, the stress point of bearing inner race is changed to by adjusting nut and is delivered on snap ring by the bolt on axle sleeve, improved greatly the bearing capacity of roller, bending roller force possesses 100% ability;
2. adopted on working roll and added bearings mounted design after axle sleeve, the life-span of having improved working roll;
3. adopt adjusting nut to carry out the gap adjustment, be conducive to the effective location of bearing;
4. solve the problem of working roll play, reduced the probability of the loosening or distortion of the damage of main transmission shaft coupling and latch;
5. solve latch distortion or loosening problem, reduced top working roll lifting jam and the stuck probability of roll line adjusting device.
