A copper tile is further arranged on the inner surface of the spherical tile, and anti-abrasion pads are arranged at the two ends of the copper tile.

Description

Technical Field

[0001] The utility model relates to the field of equipment for rotary kilns, in particular to a thrust plate structure. Background Art

[0002] When the cement kiln is running, the roller shaft often bears axial force. For this reason, a thrust plate needs to be set in the axial direction of the roller shaft. This can prevent the roller shaft from having excessive axial displacement and ensure the reliability and stability of the equipment. However, the existing thrust plate is set at the shaft head, so the axial thrust it bears is small, and it is prone to breakage. Therefore, the position of the existing thrust plate needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to provide a thrust plate structure to solve the problem that the existing thrust plate is easily broken when subjected to large axial extrusion due to its unreasonable position and small axial thrust.

[0004] In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: a thrust plate structure, including a thrust plate, a bearing shell and a spherical bearing shell. The thrust plate is installed on the end of the main shaft of the main and passive rollers close to the rollers. The bearing shell is arranged outside the main shaft of the main and passive rollers. The spherical bearing shell is arranged between the inner surface of the bearing shell and the main shaft of the main and passive rollers. The inner surface of the spherical bearing shell is also provided with a copper shell, and anti-wear pads are provided at both ends of the copper shell.

[0005] The thrust plate in this solution is located at the shaft shoulder, which can withstand 2 to 3 times greater axial thrust than the prior art in which the thrust plate is located at the shaft head. When the supporting wheel moves axially, the thrust plate originally located at the shaft head is easily broken, causing a kiln shutdown accident. However, the thrust plate at the shaft shoulder in this solution is not prone to breakage.

[0006] As a further preferred embodiment of the present invention, a gap is left between the inner end surface of the outer end of the thrust plate and the inner end surface of the inner end of the shoe shell, and the width of the gap is ≥10 mm.

[0007] Such a gap is more conducive to smooth rotation.

[0008] As a further preferred embodiment of the present invention, the total gap between the anti-wear pad located at the inner end of the copper shoe and both sides of the thrust plate is 6±0.5 mm.

[0009] As a further preferred embodiment of the present invention, a temperature measuring hole is drilled at the lower portion of the inner edge of the spherical bearing.

[0010] The temperature measuring hole set at this location can more accurately reflect the temperature of the inner surface of the spherical bearing.

[0011] As a further preferred embodiment of the present invention, the temperature measuring hole has a diameter of 9 mm, a tapping size of M10*1, and a depth of 35 mm.

[0012] As a further preference of the present invention, a 20*20mm packing sealing structure is provided at the main shaft mounting openings of the main and passive supporting wheels of the tile shell.

[0013] As a further preferred embodiment of the present invention, heat dissipation channels are evenly opened on the surface of the tile shell, and a circulating fan is provided outside the channel opening of one of the heat dissipation channels.

[0014] This is more conducive to heat dissipation and can better extend the service life of the equipment.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] 1. The thrust plate at the shaft shoulder in this solution is not prone to breakage.

[0017] 2. The accurate setting of the gap in the structure can ensure the smooth operation of the equipment.

[0018] 3. The temperature measuring hole can more accurately reflect the temperature of the inner surface of the spherical bearing.

[0019] 4. It is more conducive to heat dissipation and can better extend the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
