1.1 precautions before installation
Assembly and installation work must be carried out carefully by trained and qualified personnel;
The manufacturer is not responsible for any damage caused by incorrect assembly and installation;
At the planning stage should be to set aside enough space for future maintenance and repair work;
Be sure to prepare proper lifting equipment before starting the assembly and installation work;
If the reducer (motor) is equipped with a fan, there should be enough space for the air to be sucked into the air;
That with the power transmission device on the nameplate;
The transmission should be in good condition (not damaged in the course of transportation or storage);
Confirm that the following requirements are met:
The standard reducer: ambient temperature of 0 degrees C ~ +40 degrees C No oil, acid, harmful gas, steam, radioactive objects, etc.;
For the special type: the transmission device is based on the environmental conditions of the configuration;
The worm gear reducer: can not have a self lock function of the reducer Too large reverse external inertia moment, so as not to damage the reducer; In order to ensure good lubrication, must comply with the requirements of the installation location;
Be sure to pay attention to the warning and safety warning signs of the reducer (motor).
1.2 preparation before installation
The use of the solvent can be purchased to completely remove the surface of the output shaft and the flange of the preservative, dirt or similar materials, etc.;
Note: do not immerse the solvent in the seal lip of the oil seal, otherwise the solvent may damage the oil seal;
If the gear reducer is stored for more than 1 years, the service life of the lubricant in the bearing will be shortened;
If the filler is mineral oil or synthetic oil (CLPHC), and the amount of fuel and the installation location of the requirements, in this case, the reducer can run at any time. However, before starting to check the oil level still;
In some cases with synthetic oil (CLPPG), high level, the oil level should be corrected before starting.
1.3 reducer installation
Reducer (motor) can only according to the prescribed installation position installed on the supporting structure of the flat, vibration, torsional; box foot with a mounting flange in the installation process can not and tightened to avoid mutual rivalry;
When the bolt or the ground block is used to fix the reducer (motor) on the foundation of the concrete, the appropriate groove can be used to hold the reducer (motor); Please check the oil in the installation and installation location is consistent, if the installation position changes, please adjust the corresponding amount of oil;
To install a straight through type ventilator or to open the ventilation device to transport the rubber ring;
Do not hit and hit the shaft ends;
Vertical mounting of motor to shield measures to prevent foreign invasion or liquid (rain cover C);
When the connection box is installed, the cable is arranged at the bottom of the wire.
1.3.1 solid shaft reducer (motor) installation
Install and fix input and output drive parts (such as coupling components, etc.) on the shaft of the speed reducer;
If the parts are to be heated in advance before the installation, the correct mating temperature can be found in the size of the coupling file;
It is possible that the shaft device is not neutral, and it may be caused by the actual operation (such as thermal expansion, deflection of the shaft, insufficient rigidity of the frame, etc.);
Please refer to the specification of the corresponding brand coupling for the right of the coupling permission;
Error of license
The pair should be carried out in two mutually perpendicular axes. You can use the ruler (radial misalignment) and the feeler (angle of misalignment);
Unless otherwise specified, otherwise these parts can induction heating method for preheating, the nozzle or in heating furnace preheating.
1.3.2 with flat key hollow shaft reducer (motor) installation The solid shaft end of the working machine shall be equipped with the first part of the A standard DIN6885 type flat key, and shall be in the center hole of the end face of the DIN standard 322 DS type (with screw thread); Check the shaft and the shaft seat of the shaft and the edge of the shaft seat of the shaft and the shaft of the reducer. If necessary, repair and clean up with the proper tools; The speed reducer is provided with a screw nut and a screw, and the reaction force is provided by the hollow shaft of the speed reducer;
1 working machine solid shaft 2 reducer hollow shaft 3 flat key 4 nut 5 screw 6 nut 7 end plate
1 working machine solid shaft 2 reducer hollow shaft 3 flat key 4 nut 5 screw 6 nut 7 end plate
In addition to the nuts and screws shown in Figure 1 and Figure 2, you can also use other types of devices such as a set of hydraulic lifting devices.
Installation of hollow shaft reducer with bulging disc 1.3.3
The solid shaft end face of the working machine shall be equipped with the center hole of the DIN standard 322 DS type (with screw thread);
Installation with integral bushing;
The speed reducer is provided with a nut and a screw, and the reaction force is provided by the hollow shaft of the speed reducer;
Install with loose bushing;
A loose bushing is pushed onto the solid shaft of the working machine, and a positioning device is used to fix it firmly in place, and then the solid shaft of the working machine is pulled into the hollow shaft of the speed reducer (Fig. 1, Fig. 2);
The outer surface of the hollow shaft of the speed reducer can be added with grease in the position of the shrink disc seat;
Tighten all the fastening bolts one by one, to go through several cycles to tighten all the bolts;
Tighten fastening bolt until the front side of the inner ring and outer ring are aligned.
1.1 add lubricating oil
Unscrew the gas plug, the lubricating oil to the oil dipstick or mirror line add the correct type slightly by the position, then the plug is installed;
Has the gas reducer (motor) without refueling.
1.2 starting
Before starting the following items must be checked and recorded:
(1) oil surface height
(2) the sealing performance of the oil cooling or oil supply system piping
(3) effective seal
(4) the rotating parts are not in contact with other parts 1.3 run
Reducer (motor) for the first time to start on. If possible, should let the no-load running hours, if an exception can be gradually loading, at the appropriate time to fill the load; During operation, the speed reducer must be monitored:
The oil temperature (in continuous operation, the design of temperature reducer is: the use of mineral oil continues to run when the temperature is 90 DEG C. At a higher temperature, be sure to use synthetic oil. The maximum temperature for a short period of time can be up to 100;
Changes in running noise;
In the box and seal may leak;
Correct oil surface height;
