Z3 type swelling inner and outer cone ring, Z5 type swelling coupling sleeve, Z6 type swelling coupling sleeve

Z1 type expansion coupling sleeve is composed of inner and outer cone rings.The structure is compact and light, suitable for occasions with small installation space.It can be used instead of various key connections or interference fit connections.In order to transmit large loads, multiple pairs of expansion sleeves can be used. The single-sided compression does not exceed 4 pairs of rings, and the double-sided compression can reach 8 pairs of rings, with good centering. ...

The Z2 type expansion coupling sleeve is composed of an open double cone inner ring, an open double cone outer ring and two double cone compression rings. It is tightened with hexagon socket bolts. When tightening, the elastic ring is not axially relative to the hub. Compared with the Z1 type, the radial pressure and the transmitted load can be generated by the same pressing force. ...

The Z3 type expansion inner and outer cone rings are tightened with hexagon socket bolts, which can transmit large loads, and there is a disassembly threaded hole on one cone ring; the joint surface is longer, and the neutrality is good, which is suitable for high rotation accuracy requirements and transmission of large loads. Occasions. ...

Compared with the Z5 type, the Z4 type expansion coupling sleeve has the same taper of each cone ring, and there is a flange in the middle of the inner ring, which is easy to disassemble. The Z5 type has a longer joining surface and a smaller taper, which is used in occasions that transfer larger loads and require higher centering accuracy. ...

The main purpose of Z6 type expansion coupling sleeve (referred to as expansion sleeve) is to replace the coupling effect of single key and spline to realize the coupling of mechanical parts (such as gears, flywheels, pulleys, etc.) and shafts to transmit loads. Its function In use, it is divided into two categories: expansion and locking. ...

The Z8 type expansion coupling sleeve transmits large torque for a long time during work, which is easy to cause fatigue and deformation of the metal, causing fatigue and wear between the expansion sleeve and the fastener. At the same time, the sintering machine is generally large, which makes it difficult.In response to such problems, polymer composite materials can be used for on-site...

The structure, dimensions and installation method of Z9 type expansion sleeve products (expansion sleeve) are common to similar products, and all comply with ISO standards.Technical instructions and technical performance can meet the requirements of the use of the machine, and are also basic accessories for domestically produced replacement parts. ...

Z11 type expansion coupling sleeve positioning, simple hub hole, wide application.Has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger fit gap, the bolts are loosened when disassembling, so that the connected parts can be easily disassembled.When swelling, the contact surface is tightly fitted and does not rust, and it is easy to disassemble. ...

Z12 type expansion coupling sets (Z12 type expansion sets) are widely used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, engineering machinery, various types of machine tools and interchangeable mechanical transmission connections. ...

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. ...
