Merchandise Description


decide on dimension fourteen-90mm, tape Z11 keyless shaft hub locking gadget shrink disc (JB/T7934-1999)


Keyless locking devices is a new kind of advanced mechanical basic parts ,been widely used in worldwide to realize the transmission of load via friction of tightening twelve.9 higher-power screws.


The main function of locking devices is to replace the joint purpose of the one essential and the spline to recognize the link of the mechanical parts (these kinds of as gears, flywheels, pulleys, and so forth.) with the shaft to transmit the load.



locking gadgets have many special positive aspects more than the standard interference joint and keyed joints:
(one) Use of locking products make the manufacture and set up of the major areas simple. The machining of the shaft and the hole in which locking unit is mounted does not need high precision producing tolerances like an interference match. There is no require to warmth, amazing or pressurize the locking gadget, just tighten the bolts to the required torque. The hub can be effortlessly altered to the sought after placement on the shaft. Locking gadgets can also be utilised to join areas with bad weldability.
(two) The locking gadget has a lengthy provider life and large power. It relies on the friction for transmission, and there is no key groove weakening on the joint member, and there is no relative movement, and no put on happens for the duration of the perform.
(three) When the locking device is overloaded, it will shed the coupling result and defend the tools from injury.
(four) The locking device can bear multiple loads, and its structure can be produced into different designs. Dependent on the dimensions of the installed load, it is also achievable to use multiple locking gadgets in series.
(5) The locking device is easy to disassemble and has very good interchangeability. Because the locking device can merge the hubs with large matching gaps, the bolts can be loosen during disassembly, so that the joints can be easily disassembled. When the growth is restricted, the get in touch with area is tightly fitted and is not simple to result in rust, and straightforward to be coupled and disassembled.


Application: mining equipment, coal mining machinery, ball mill, belt conveyor, packaging machinery, heavy machinery, gentle industrial machinery, meals equipment, CNC machine equipment, metallurgical equipment, textile equipment, printing machinery, plastic machinery, chemical equipment, paper equipment, Marine equipment, tobacco machinery, fans, blowers, reducers, etc.



Model: Z11 type locking devices 




Area: polished

Material: 45# steel 

Nominal torque/ rated torque: .068kNm-12.75kNm 

Hole diameter: 14mm-90mm 



Application:A hub with a tiny internal diameter can be connected.
Attributes: It can be connected to a hub with a little internal diameter. There is a self-centering operate. When related, there is no axial motion of the hub.


one, set up:

The locking system is greased at the manufacturing facility and can be put in directly. When setting up, 1st screw 3 bolts 4 into the screw holes of the flange of the other component one and distribute them evenly around the circumference to open up the interior sleeve 1 and the outer sleeve 2. Then location the growth sleeve into the hub gap of the style situation and tighten the bolt with the force gauge. The method of tightening is to screw every single bolt to one/4 of the rated torque at a time. The buy of tightening is bounded by the slit. The left and appropriate cross symmetry is tightened a single following the other to make sure that the rated torque benefit is arrived at. 

2. Disassembly:

Loosen all bolts a few turns before disassembly. Then screw in the bolt 4 best unfastened sleeve in the disassembled screw gap. 

three. Safety:

MoS2 oil is strictly prohibited for the duration of set up to avoid contamination of the expansion sleeve. On machines with poor open air or operating atmosphere, rust-proof grease ought to be used regularly on the uncovered stop confront and bolts of the growth sleeve. The enlargement sleeve type with greater rust resistance need to be chosen.

Z11 keyless locking devices main dimensions for your variety choice.
