Description

The invention relates to mechanical engineering, namely to bearings and shafts operating during abrasive wear in dirty grease or without grease. A rolling bearing is known. Comprising an outer ring, an inner ring with a component integrally extending to the side with a gear set loose thereon a separator with teeth, a section of the rolling body,

The main disadvantage of this known rolling bearing is that it interacts with a gear cage under conditions; abrasive wear when sliding glide, and- i

moreover, a rapidly wearable, elongated to the side part of the inner ring made of bearing steel and hardened, made without the possibility of replacement when it is worn, and it does not have a limiter for the axial movement of the gear cage away from the rolling elements, which makes it difficult to restore the worn gear saparator is a working shaft. These noted shortcomings of this known bearing increase its maintainability and save the cost of production, since expensive bearing steel are elongated hydrochloric the manufacture of the inner ring not carrying a load on the bearing, and a notched centering separator

holding a limiter of its axial displacement adjacent to the end-face-vertex of the annular groove of the gear separator away from the rolling elements

The main disadvantage of this known rolling bearing is the fact that it has a gear cage mounted on the side of the ring. This eliminates the possibility of replacing the flange of the inner ring that is worn during abrasive wear, which impairs the maintainability of the known rolling bearing - Also, in the specified known bearing the limiter of axial movement of the cage separator away from the rolling elements is made in the form of an independent separate detap - spring washer, which complicates, and therefore , raises the cost of the bearing design, while the need to make an annular groove in the annular groove of the gearbox to install a spring bolt in it eliminates the possibility of Bi (replenishing a sufficient clearance of the gear sepsfator, without which it is impossible to use such a bearing when abrasive wear on dirt lubrication, when in the rolling bearing the radial clearance and the axial play of the valley are performed - increased.

The purpose of the invention is to improve the repairability and cheaper products

For this, the inner yule and made mainly of carbon steel elongated to the side, the part is made integral with the limiter of its axial displacement adjacent to the end surface of the annular groove of the gear cage to the side of the rolling elements, connected together by means of a washer-shaped located between them a layer of repeatedly-re-possessing adhesive properties of a substance, mainly Itum, a high-temperature oil mulchigep, usually used as a The company is a manufacturer in the production of rubber., which has a strong adhesion to NetMap ::

ring 2 with its integral part elongated to the side, part 3 with a freely toothed separator 4 with teeth 5 separating heat rolling 6 For operation with abrasive wear in dirty grease or without grease, the gear separator is cast mainly from cast iron, in particular from cast iron of the Sch brand, 15-32, while the elongated side part 3 of the inner ring 2 is mainly made of carbon steel, in particular, steel of the St grade. 3 This ensures that the anti-friction pair is resistant to wear, and the cost of production is reduced. The inner ring 2 and made of carbon steel are elongated to the side of part 3, made integral with the annular groove 8 of the toothed separator of the limiter adjacent to the end surface 7

axial latra 16 are made for clamping gear cage A between the additional ring I I and the rolling elements 6

The implementation of an annular groove 8 in the gear separator A and placement of an axial displacement limiter 9 therein of the gear separator 4 makes it possible to reduce the size of the proposed non-flow bearing in the direction along the shaft. This reduces the consumption of materials manufacturing gear separator and the additional ring 11 and, thereby, reduces the cost of production.

The implementation of the limiter H axial movement of the gear cage 4 in CTnpoHj from heat rolling, as one

the whole with the elongated part 3 of the inner ring 2, reduces the complexity of the bearing design, and thereby reduces the cost of production:

Prior to the general assembly of the proposed rolling bearing, bitumen is applied to the end surfaces of the inner ring 2 and the additional ring 11 facing the washer 1P. In the general assembly of the proposed rolling bearing, after installing all of its parts therein, by means of a press, the additional ring 11 rises to the inner ring 2. In this case, the bitumen forming the washer layer 10, previously deposited on the surface of the rings 2 and 11, is transferred from the solid state to a viscous igidosis and, in the form of a step, the bonded layer 10 sticks together rings 2 c 11

After removing the load applied by the press, the formation of the shank-like layer 10 bitumen from a viscous liquid state becomes solid, which ensures a rigid connection of rings 2 and II into one piece Teplyn, with the general assembly of the proposed rolling bearing, it is not necessary to ensure the accuracy of coincidence of the axes inner ring 2 and additional ring 1I, This is explained by the fact that if there is a misalignment, rings 2 and 11 are indicated, during the installation of the proposed rolling bearing on a working EEL, under the action of the attached: and with this force, one of the rings 2 or 9 will self-bias in the radial direction to the position that

the alignment of rings 2 and H, since. If the puck is in place, Bitumen will not prevent it; bitumen under the action of forces from the solid state will again turn into a viscous liquid state, and, after mounting the bearing on the working shaft, in the washer 6iiTVM will again become solid and, moreover, rings 2 and II are again 6vovT firmly connected together in one chain, General assembly technologists of the proposed rolling bearing are very simple "which reduces the cost of production" Such general assembly bearings of the rolling bearing provides the possibility of replacing worn gear cage k and additional ring 11, as well as rolling heat , Directly to the E operating conditions of the machines, or is equipped with m new gear cages i |, an additional ring 11 and rolling elements b, supplied by the manufacturer of bearings, as they are in stock -. parts, It improves the repair ability of the proposed bearing on

When the proposed rolling bearing is used, the axial displacement limiter 9 of the gear cage k E side of the rolling elements 6 eliminates the possibility of wear of the working shaft, which improves the repair quality of the proposed rolling bearing,

The use of the proposed rolling bearing is rational in many respects at a frequency of rotation of up to 100 rpm, with abrasive wear in contaminated grease or without SM31KI, in machines that work with mortars; - and in equipment, separately in conveyors and in - barrels of an organ-gold mining drag into a machine for continuous casting of billets of metallurgical plants. The use of the proposed rolling bearing will reduce all types of operating costs for the corresponding machines and equipment.
