Abstract
The utility model discloses a roller bearing composite structure for ball mill, wherein, a bearing is nested outside the mill axis of the ball mill and is made of an outer-ring non-flange biserial cylindrical roller bearing; the external surface of the outer ring is made into a bidirectional circular arc capable of making the bearing produce self-aligning center adjustment ranging from 1 degree to 3 degrees; both ends of the outer ring of the bearing are actively arranged on a bearing seat. The bearing adopted by the utility model possesses ideal self-aligning performance; meanwhile, due to both ends of the outer ring of the bearing being actively arranged on the bearing seat, the problem of obvious axial float of the mill caused by expansion from heat and contraction from cold can be solved.
Description
Technical field
The utility model relates to a kind of ball mill, particularly a kind of bearing combining structure that is used for ball mill.
Background technology
Being applied to traditional ball mill that metal and nonmetallic ore dry powder and slurries grind in the production is that a level is contained in two rotating cylindrical shells of the low speed on the bearing.
Large-size ball mill generally adopts the spherical bush sliding bearing, configuration high-low pressure Lubricating-oil Station, and by hydraulic oil jack-up cylindrical shell, after the grinding machine starting, the low pressure oil starting makes grinding machine keep operation, and hydraulic oil stops.This airframe bearing can make grinding machine realize axial float and radially adjustment, but this airframe bearing exists auxiliary equipment such as sealing problem and configuration high-low pressure oil station, and cost is bigger, complex structure; Because development of technology, rolling bearing maximizes, make present middle-size and small-size grinding machine generally adopt conventional rolling bearing, dry oil lubrication, the axial motion of grinding machine is realized by the different structure of bearing block, structure is complicated, poor practicability, and this is the main cause that present bearing is still continued to use the spherical bush sliding bearing.
The frame mode and the bearing block structure mode of the rolling bearing that ball mill adopts in the prior art generally adopt the activity of grinding machine on-fixed end bearing seat, and its shortcoming is not suitable for large-sized grinder, cause grinding machine to damage easily; Adopt common rolling bearing in addition,, cause bearing to damage easily because mill load is bigger.
The utility model content
The technical problems to be solved in the utility model provides a kind of roller bearing combining structure that is used for ball mill, can carry out radially aligning and elimination axial float.
For solving the problems of the technologies described above, the utility model is used for the roller bearing combining structure of ball mill, bearing holder (housing, cover) is connected on outside the grinding machine axle of ball mill, the inner ring of bearing and grinding machine axle are fixed, bearing does not have the rib Biserial cylindrical roller bearing by the outer ring to be made, and the outer surface of its outer ring is made into and can makes bearing produce the two-way circular arc of 1 °~3 ° self-aligning.
The two ends of the outer ring of bearing and bearing block employing activity are installed.
The utility model is because employed bearing is not have on the basis of rib Biserial cylindrical roller bearing NN series bearing in the outer ring, the bearing outer ring outer surface is processed into two-way circular arc, allow it that self-aligning of 1 ~ 3 ° is arranged, change the shortcoming of this series bearing aligning difference, make the adjusting play is radially arranged between grinding machine and the bearing block, the two ends of the outer ring of bearing and bearing block employing activity simultaneously installed, and can compensate the bigger axial movement value problem of grinding machine because of expanding with heat and contract with cold and producing.
Description of drawings
Fig. 1 is the schematic diagram of used bearing in the utility model;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is used for the roller bearing combining structure of ball mill, and bearing 1 is socketed in outside the grinding machine axle 31 of ball mill 3, as shown in Figure 2; The two ends of the outer ring 12 of bearing 1 and bearing block 2 employing activities are installed; 11 of the inner rings of bearing 1 are fixing with grinding machine axle 31, fix with step and spacer sleeve mode as the inner ring 11 and the grinding machine axle 31 that can adopt bearing 1.Bearing 1 is further to be processed on not having the basis of rib Biserial cylindrical roller bearing NN series bearing in the GB/T285 outer ring, the outer surface of its outer ring 12 is made into is processed into two-way circular arc, so that bearing produces 1 °~3 ° self-aligning, as shown in Figure 1.This two-way circular arc makes that bearing width direction middle part is full-size R, and two edges are measure-alike and less, contact with bearing block 2 to guarantee the full-size place, and the gap is left at all the other positions.
Bearing in the utility model adopts application GB/T285 outer ring not have the rib Biserial cylindrical roller bearing and makes, utilize the characteristic of the outer ring 12 no ribs of bearing 1, bearing 1 inner ring 11 can be relatively moved at axis direction with outer ring 12, alleviate the axial float problem of grinding machine because of expanding with heat and contract with cold and producing; The two ends of the outer ring 12 of bearing 1 and bearing block 2 employing activities are simultaneously installed, the bigger axial movement value that produces in the time of can compensating grinding machine 3 work; This two-way circular arc has then changed the shortcoming that the GB/T285 outer ring does not have rib Biserial cylindrical roller bearing NN series bearing aligning difference, make between grinding machine axle 31 and the bearing block 2 adjusting play is radially arranged, two-way circular arc both can help to solve ball mill axial float problem, had the self-aligning function again.
The bearing 1 that the roller bearing combining structure of ball mill of being used for the utility model is adopted is two-way garden arc self-aligning axial displacement roller bearing, its size specification is: 360mm≤bearing bore diameter d≤1280mm, 560mm≤bearing outside diameter D≤1700mm, 135mm≤bearing width b≤300mm, the two-way circular arc R≤2720mm of bearing 2080mm≤external diameter; Be applicable to the non-transmision end roller bearings of ball mill series of products of all specifications of 900mm≤ball mill barrel diameter of phi≤3200mm.Numerical value corresponding relation such as following table between the different size specification between above-mentioned bearing bore diameter d, bearing outside diameter D, bearing width b, the two-way circular arc R of bearing outside diameter, the ball mill barrel diameter of phi that is suitable for:
Ball mill barrel diameter of phi (unit: mm) | Bearing specification (unit: mm) | |||
