Improper installation method will cause damage of motor's encoder. Please note the following during the
installation process:
◆
When operators installation pulleys on the servo motor shaft with key, it is necessary to use screw hole. In
order to install pulleys, operators need to insert double-headed nail into screw holes and use washers on the
surface of coupled end. Then use nuts to fix into pulleys gradually.
◆
For servo motor shaft with keys, Operator need to use screw hole on the shaft to install. For motors shaft with no
key, operators need to use friction coupling or other analogous methods.
◆
When operators need to disassemble pulleys, operators need to use pulley remover so as to make shaft
avoid strong impact of load.
◆
In order to make it more safe, it is necessary to install protection cover or some analogous equipment in
rotation area. For example, pulleys installed on the shaft.
◆
When it is connected with machine, please use coupling and make shaft center of servo motor and machine stay in
a line. When operators install servo motors, please achieve requirements of centering accuracy. If centering is not
accurate, there will be shock and sometimes it will make bearings and encoders
When it is used in the occasion with drops, please use after make sure protection level of servo. When oil will
drop into shaft penetrating part (beside shaft penetrating part, please choose servo motors with oil seal. The
using condition of servo motors with oil seal:
◆
Make sure the oil level is lower than month of oil seal.
◆
Please use when oil seal make sure that oil splash degree is good.
◆
When servo motors are installed in vertical upward direction, please avoid oil accumulating in the
month of oil seal.
The motor bearing has its own double-sided dustproof effect, and the assembly of the oil seal will increase the loss
of the motor, resulting in a decrease in the efficiency of the motor. If it is not a place where oil seals must be
installed, it is not recommended to install oil seals. Before assembling the oil seal, please ensure that the installation
holes and the oil seal are free of debris, oil, dust, etc. When assembling, please fill the oil seal sealing lip with high-
temperature grease (recommended to use Great Wall's HP-R grease, with a temperature resistance of 180
degrees). Strengthen the performance of lubrication and temperature resistance and increase the sealing and
waterproof effect of the oil seal. When paying attention to water and oil resistance, the side of the oil seal with the
self-tightening spring (that is, the side with the groove) is installed towards the motor. Please refer to the following
steps to install the oil seal correctly.
1. Evenly apply high temperature lubricating oil to the sealing ring of the oil seal lip.
2. the oil seal has a groove side facing inward, ensure that the oil seal is perpendicular to the machine shaft, use a
suitable sleeve to push the oil seal into the cavity.
3.After successful installation, check whether the oil seal is tilted. The oil seal should be fitted with the motor bearing
cover, and the lip of the oil seal should be completely closed to ensure the tightness of the oil seal.
