As a further aspect of the utility model: the clamping structure comprises an annular strip, the annular strip is embedded and arranged outside the cylindrical inner roller, and a plurality of clamping holes which are distributed in an annular mode are formed in the outer side face of the annular strip.

As a further aspect of the utility model: the number of the clamping rods is multiple, and two adjacent clamping rods are clamped in the same clamping hole in a butt joint mode.

As a further aspect of the utility model: the shape of the groove is set to be hexagonal, and the shape of the second magnet is matched with the shape of the groove.

Compared with the prior art, the utility model has the beneficial effects that:

1. this roller for cylindrical roller bearing, through setting up first magnet, second magnet and cylinder roller, when dismantling, at first two cylinder rollers of operation drive first magnet and second magnet separation, then cylinder roller deviate from the cylinder inner roller for separate demolish between cylinder roller and the cylinder inner roller, and then can change the cylinder roller alone when the cylinder roller produces wearing and tearing, avoid the whole change of cylinder roller and cylinder inner roller, and then avoid the waste of material, the change of some great cylinder rollers of specially adapted.

2. This roller for cylindrical roller bearing is through setting up screens hole and screens pole for the screens pole can dock and insert in the screens hole, and the length of screens pole equals half of screens hole inner chamber length, and then makes two screens poles can block into same screens hole, can increase the connection stress between two cylinder rollers simultaneously.

3. This roller for cylindrical roller bearing is through setting up first magnet and second magnet, when the cylinder roller cover is established on the cylinder inner roller for produce magnetism actuation between first magnet and the second magnet, and then can be to the fixed position of cylinder roller, avoid cylinder roller and the problem of cylinder inner roller separation.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

As shown in fig. 1-4, the present utility model provides a technical solution: the roller for the cylindrical roller bearing comprises a cylindrical inner roller 3, wherein two cylindrical rollers 1 which are in butt joint with each other are sleeved outside the cylindrical inner roller 3, the cylindrical rollers 1 and the cylindrical inner roller 3 are connected in a split assembly mode, and then the roller sleeves can be detached independently, a side handle 2 is arranged on one end face of the cylindrical rollers 1, and the side handle 2 can provide a force application point so as to facilitate the direct separation of the cylindrical rollers 1 and the cylindrical inner rollers 3;

the side handle 2 is flush with the end face of the cylindrical roller sleeve 1, the butt joint positions of the two cylindrical roller sleeves 1 are fixedly connected with the clamping rods 8, the number of the clamping rods 8 is multiple, two adjacent clamping rods 8 are in butt joint and are clamped in the same clamping hole 52, the clamping rods 8 are clamped with the clamping structures 5, the clamping rods 8 can be inserted into the clamping holes 52 in a butt joint mode, the length of the clamping rods 8 is equal to half of the length of the inner cavity of the clamping holes 52, and therefore the two clamping rods 8 can be clamped into the same clamping hole 52, and meanwhile the connecting stress between the two cylindrical roller sleeves 1 can be increased;

the clamping structure 5 comprises an annular strip 51, the annular strip 51 is embedded and arranged outside the cylindrical inner roller 3, a plurality of clamping holes 52 which are distributed in an annular mode are formed in the outer side face of the annular strip 51, the clamping structure 5 is arranged outside the cylindrical inner roller 3, grooves 4 are formed in two ends of the cylindrical inner roller 3, the grooves 4 are arranged in a hexagonal shape, the shape of the second magnet 7 is matched with that of the grooves 4, the grooves 4 and the second magnet 7 are of a hexagonal structure, and further the problem that the cylindrical roller 1 rotates on the cylindrical inner roller 3 to generate internal abrasion is prevented, and meanwhile abrasion between the first magnet 6 and the second magnet 7 is avoided;

fixedly connected with first magnet 6 in recess 4, and two first magnet 6 respectively with two second magnet 7 magnetism actuation, when cylinder roller 1 cover is established on cylinder inner roller 3 for produce magnetism actuation between first magnet 6 and the second magnet 7, and then can be to the fixed position of cylinder roller 1, avoid cylinder roller 1 and cylinder inner roller 3 separation's problem, two second magnet 7 respectively fixed connection are at the inner chamber terminal surface of two cylinder rollers 1.
