Gear installation and disassembly method of Roots blower
Roots blower I think we can't be more familiar with it. We can't avoid maintenance in the process of use, Roots blower The installation of gear is the most important, the adjustment of impeller clearance is also the adjustment of gear clearance. Today, Hong Guang made a summary Roots blower Installation and disassembly of gear.
1： Installation method
On installation Roots blower Please install the driving gear first and then the driven gear. When the gear and shaft are connected by a flat key, the flat key is first installed on the shaft and the side of the key. Apply lubricating oil, and then put the gear shaft hole against the shaft, align the keyway on the hole with the flat key, and then install the gear on the shaft. Common installation methods are as follows.
1: when Roots blower When the taper of gear and shaft match, first put the driving gear on the drive shaft, install the round nut on the gear locking part, then knock the gear end face with copper rod and tighten the round nut. When fully locked, retract the round nut, add a thrust washer, and formally lock the lock. Then, put the driven gear onto the driven gear, rotate the steering wheel according to the specified operation, and check the clearance between the two impellers. Change the circumferential position between the driven gear ring and the hub, and adjust the direction of the impeller. The driven gear is locked after the impeller clearance is confirmed.
As a result of the tight fit of the cylindrical gear, the shaft will require a large fit if the pressure is great. Usually, place the sleeve on the end face of the sleeve, usually by hand, by tapping on the end face of the sleeve. Hit the end face of the gear, push the gear up on the shaft and lock the gear when it reaches the shoulder.
2、 Disassembly method
1： Roots blower The disassembly sequence of the gear is: first remove the round nut and liner washer and other fasteners, and then pull the gear. If it is too tight, the gear can be heated and pulled properly. When pulling the gear, in order to prevent the gear from rotating with screws, a bunch of cloth or cotton yarn can be inserted into the synchronous gear. At the same time, in order to prevent the gear from falling off the shaft, the round nut can be left on the shaft when the impeller is turned.
2. All used gears shall be assembled according to the original wear marks according to the direction marks during disassembly, so as to avoid poor meshing of tooth surfaces. If a new gear is used, operate both the master and driven gears at the same time. Replace. Otherwise, the matching of old and new gears will cause poor contact.
Summary: the above points are the summary of this small series in practice, the specific situation depends on the original installation of the fan, different regions Roots blower It's a little different, but everything is the same. You can be more careful when installing and disassembling. If you don't understand or can't figure out the situation, please call our customer service or wechat 18668919566
