Abstract
The invention relates to the technical field of technical processing of a bearing. A process method for the split processing of an SL type split bearing comprises the following steps: 1. when a product is processed by a lathe, opening annular guiding process grooves at the middle position of the generating line of an outer ring of a bearing to be split and at a position corresponding to a ball race, wherein the wall thickness between two notches is determined according to the allowance size of the grinding procedure provided by the turning procedure so as to ensure that the wall thickness between the two notches of a finished product is between 1.5 and 2 millimeters; 2. after finishing all the grinding processing procedures on the outer ring and before the assembling procedure, opening a transverse incision on the outer ring to be split along a guiding groove in a linear cutting mode, wherein the length of the incision is determined according to the size of the product; and 3. applying certain force on an opening to divide the outer ring into two parts so as to realize the split. The process method has strong processing manufacturability, can meet the product design requirement and realize batch processing, and improves the processing efficiency.
Description
Technical field
The present invention relates to the processes technical field of bearing, relate generally to a kind of subdivision technological method for processing of SL01 type split bearing.
Background technique
The SL cylindrical roller is the overweight main bearing of double-row full-complement roller-type, two kinds on fixed side (SL01 type, SL04 type) and free side (SL02) type arranged, this class bearing is the thinnest dimension series of wall thickness in the iso standard defined dimension series, and can bear very large radial load and impact load, the fixed side bearing also can bear the bi-directional axial load by roller except that radial load in addition.Therefore, be widely used in fields such as engineering machinery, vehicle, iron and steel, elevating mechanisms, this bearing outer ring or inner ring circumferencial direction need to cut apart with special process, roller is installed then and is fixed as one the type structure.At present, domestic because of its subdivision processes technology is difficult to grasp, the bearing enterprise of energy production the type is very few.
Summary of the invention
The subdivision technological method for processing that the purpose of this invention is to provide a kind of SL01 of relating to type split bearing makes this method technology capability strong, can satisfy the product specification requirement and can realize batch process, improves work efficiency.
Invention task of the present invention adopts following technological scheme to realize:
The present invention takes the outer ring technological method of subdivision radially;
1, product is when Vehicle Processing, bearing outer ring external diameter bus neutral position and raceway relative position at the need subdivision promptly need be cut position open loop shape guiding technology groove open, annular guiding technology groove on the bearing outer ring external diameter guides the technology groove notch relative with the annular on the raceway, the line of steering channel is perpendicular to the shaft axis of outer ring, wall thickness between two notches is given according to the turning operation and is ground operation allowance size and determine, guarantees the wall thickness 1.5～2mm between two notches of finished product;
2, after the outer ring being finished all grinding operations, enter assembly process before, the outer ring of need subdivision is opened transverse incision along steering channel with the line cutting mode, incision length is formulated according to product size, is 1/6～1/8 of bearing outer ring girth;
3, apply certain force at opening lasso is divided into two, realize subdivision.
Subdivision technological method of the present invention adopts carries out subdivision after grinding is finished, be beneficial to product processing; And the every precision that makes product is easy to guarantee.
Subdivision technological method of the present invention is convenient to cut open at subdivision Position Design annular guiding technology groove; When cutting open, do and guide into, guaranteed to cut the accurate of position open, do not split to other direction.
Subdivision technological method of the present invention is opened the transverse incision of certain-length with the line cutting mode at need subdivision position, guaranteed cutting open smoothly the outer ring; Be beneficial to product assembling back butt joint, can not influence required precisions such as outer ring dimensional accuracy and parallelism.
Subdivision technological method technology capability of the present invention is strong, is easy to grasp and realizes, and can satisfy every index request such as product performance, realizes product lot quantityization, efficient activity.
Description of drawings
Accompanying drawing 1 is the SL01 type split bearing schematic representation that inside and outside steering channel is arranged and have transverse incision.
Accompanying drawing 2 is that the A of Fig. 1 is to schematic representation

SL01 type split bearing outer ring schematic representation behind accompanying drawing 5 subdivisions.
Accompanying drawing 6 is that the A of Fig. 5 is to schematic representation.
Among the figure, 1, need the bearing outer ring of subdivision, 2, the external diameter steering channel, 3, the raceway steering channel, 4, need the split bearing position, 5, lock ring, 6, the lock ring groove, 7, the line cutting mouth.
Embodiment
In conjunction with the accompanying drawings, technological method of the present invention is specified:
As shown in Figure 3, reaching (need cut the position open) 4 open loop shape technology steering channels 2,3 on the raceway relative position, steering channel 2,3 the shaft axiss that set on the external diameter bus neutral position of SL01 type split bearing outer ring 1 during Vehicle Processing perpendicular to bearing; As shown in Figure 4, after grinding is finished, open transverse incision 7 along steering channel with the line cutting mode, incision length is decided according to the size of bearing diameter, is about 1/8 of bearing outer ring girth; Apply certain force the outer ring is divided into two having the steering channel place, realize subdivision.Product assembling back is by former interface butt joint, along three lock rings 5 are installed respectively in three locked grooves 6 of outer ring circumference uniform distribution the outer ring fixed then.Fig. 5 is for cutting rear bearing lasso schematic representation open.
Claims (1)
