Z13 type expansion coupling sleeve
When the rated load of the Z13 expansion coupling sleeve is less than the load to be transferred, two or more expansion sleeves can be used in series, and the total rated load is: Mtn=m.Mt where: Mtn---n total rated expansion sleeves Load; m-load factor.
Tolerance and surface roughness of the bonding surface.
1.与胀套结合的轴和孔，其公差带按GB1800-79《公差与配合总论标准公差与基本偏差》和GB1801《公差与配合尺寸至500mm孔、轴公差带与配合》的规定。
2. The tolerance zone of the shaft and hole combined with the expansion sleeve is in accordance with the provisions of GB1031-83 "Surface Roughness Parameters and Values".The recommended ten-point height Rz of microscopic unevenness is listed in Table B.
The inner and outer cone rings of the Z13 expansion sleeve are tightened with hexagon socket bolts. The joint surface is longer and the neutrality is good. It is suitable for occasions with high rotation accuracy requirements and large load transmission.

Z13 type expansion sleeve is a kind of basic component widely used for mechanical connection under heavy load today. In the connection of wheel and shaft, it is a kind of load transmission by tightening the bolt to make the pressure and friction between the containing surface. Keyless coupling device.
The expansion sleeve is a keyless coupling device. Its principle and purpose is to generate huge holding force between the inner ring and the shaft, and between the outer ring and the hub through the action of the tension bolt, so as to realize the non-contact between the machine and the shaft. Key connection.When under load, torque, axial force or the combined load of the two are transmitted by the combined pressure of the expansion sleeve, the machine, the shaft and the accompanying friction force.The expansion sleeve connection has the following advantages: centering; easy installation/adjustment/disassembly; stable connection; it can protect the equipment from damage when overloaded, especially suitable for transferring heavy loads.It is widely used in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment, etc.
