Background technique
Roll squeezer work roll spring bearing belongs to low-speed heave-load, the bearing ratio is pressed with higher asking, but linear velocity is low, roll squeezer all adopts rolling bearing for a long time, as selfaligning roller bearing, four row roller bearings etc., what wherein obtain comparatively extensive use is biserial roller spherical self-aligning bearing, and this bearing structure is all described in Chinese invention patent CN1853050A and utility model patent CN201030310Y to some extent.But at present roll squeezer faces the maximization market demand, and the manufactured materials of large-size rolling bearing and technological requirement are higher, and it is long to have a manufacture cycle, and quality can't guarantee, the high limitation of manufacture cost.
Summary of the invention
The objective of the invention is to: a kind of low cost of manufacture is provided, can satisfies the spherical aligning sliding bearing for roll squeezer of quality requirement, replace the rolling bearing that adopts at present.
Technological scheme of the present invention is:
A kind of spherical aligning sliding bearing for roll squeezer, it is characterized in that: roll squeezer work roll shaft supporting section is assemblied in the spherical bush in the mode of sliding friction, spherical bush is installed in the concave spherical surface seat, the concave spherical surface seat that matches with spherical bush is fixedly mounted in the bearing support, restriction spherical bush and concave spherical surface seat is installed along the limiting stopper of roll squeezer work roll shaft circumferencial direction to slip in bearing support.
Supplementary technology scheme of the present invention is as follows:
Preferably, also be set with axle sleeve outside roll squeezer work roll shaft supporting section, the outer round surface of axle sleeve places in the spherical bush internal circular surfaces, radially slides friction pair with composition in the spherical bush internal circular surfaces.
Preferably, described spherical bush is the spherical bush smaller or equal to 180 ° of cornerites.
Preferably, the angle between described spherical bush and concave spherical surface seat plane of the opening and the vertical direction is 45 °.
Preferably, between the bearing support of the relative side of concave spherical surface seat and axle sleeve, thrustor is installed.
Preferably, have positive stop lug boss, reserve the gap of 3～15mm between positive stop lug boss and the spherical bush at the two ends of axle sleeve.
Preferably, have positive stop lug boss, form the axially movable matching relationship of restraint of labour roller between positive stop lug boss and the spherical bush at the two ends of axle sleeve.
The invention has the beneficial effects as follows: can replace the rolling bearing that adopts at present in the roll squeezer, sliding bearing is easy to manufacture, the higher and low cost of manufacture of end product quality; Spherical bush smaller or equal to 180 ° of cornerites makes bearing more convenient in installation process; Spherical bush and concave spherical surface seat 45 ° the design equal support rollers uniformly can satisfy roller loading direction changes under fully loaded and unloaded situation time that tilts.
Description of drawings
Fig. 1 is the structural drawing of spherical aligning sliding bearing for roll squeezer of the present invention.
Fig. 2 is that spherical aligning sliding bearing for roll squeezer of the present invention is installed in the schematic representation in the roll squeezer.
Wherein, reference character: 1 is the roll squeezer work roll, and 2 is thrustor, and 3 is limiting stopper, and 4 is spherical bush, and 5 is the concave spherical surface seat, and 6 is bearing support, and 7 is axle sleeve, and 8 is positive stop lug boss.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Specific embodiments of the invention 1, a kind of spherical aligning sliding bearing for roll squeezer, include and be used to be sleeved on 1 supporting section Upper shaft sleeve 7 of roll squeezer work roll, the outer round surface of axle sleeve 7 places in spherical bush 4 internal circular surfaces, form and radially slide friction pair, be that axle sleeve 7 forms the sliding friction matching relationship at spherical bush 4 internal surfaces, spherical bush 4 is installed in the concave spherical surface seat 5, the concave spherical surface seat 5 that matches with spherical bush 4 is fixedly mounted in the bearing support 6, restriction spherical bush 4 and concave spherical surface seat 5 are installed along the limiting stopper 3 of axle sleeve 7 circumferencial directions to slip in bearing support 6, make spherical bush 4 only can form a certain amount of displacement, realize the aligning function of bearing with the roller axle disturbance.The complete spherical aligning sliding bearing of final formation, as shown in Figure 1, 2.In embodiment 1, for simplified structure, also can be without axle sleeve 7, directly 1 supporting section of work roll is assemblied in spherical bush 4 internal circular surfaces, composition radially slides friction pair in 1 supporting section outer round surface of work roll and spherical bush 4 internal circular surfaces, and promptly axle sleeve 7 forms the sliding friction matching relationship at spherical bush 4 internal surfaces.
A kind of optimal way of the spherical aligning sliding bearing for roll squeezer of the embodiment of the invention 1, two ends at roll squeezer driving end axle sleeve 7 have positive stop lug boss 8, form the axially movable matching relationship of restraint of labour roller between positive stop lug boss 8 and the spherical bush 4, play the effect of location; Non-transmision end is reserved the gap of 3～15mm between the positive stop lug boss 8 of axle sleeve 7 and the spherical bush 4, be used to compensate the effect of expanding with heat and contract with cold.
In the above-described embodiments, the spherical bush 4 preferred half-watts that adopt smaller or equal to 180 ° of spherical aligning sliding bearing are convenient to install and make, and can increase manufacturing and installation difficulty when cornerite surpasses 180 °; Smaller or equal to 180 ° half-watt spherical bushs 4 and 45 ° of layouts of concave spherical surface seat 5 inclinations, load is evenly born in the variation of loading direction when being used to adapt to unloaded and heavy duty.
In the above-described embodiments, unsceptered in order to prevent the work roll preshoot, can between the bearing support 6 of concave spherical surface seat 5 relative sides and axle sleeve 7, thrustor be installed.Can also pass through contact temperature-measuring watt detection axle sleeve 7 outer round surface, promptly and accurately grasp the temperature conditions of tiling friction pair.
The structural dimensions that should note bearing in design process should satisfy: a. specific pressure＜=20MPa, b. linear velocity=0.5-3m/s.Maximum load and rate request when the selection of the tiling friction material of spherical bush will guarantee to use, and stop enough rich degree.
