Maintenance of the Rolling Bearing
1. Grease Feed
|1||Totally-enclosed bearing that is free of maintenance is adopted for
the small size matched electrical machinate of the company, no
lubricating grease is required to be filled in, and large size
electrical machines have obvious lubricating marks.|
|2||For the electrical machinery of the water pump, if the time from
the ex-work to the running or from the stop to another stop exceeds
three months, please be noted that new oil must be replenished!|
|3||The structure of the grease discharge port is invisible, so the
grease needs to be pressed until the sound of the bearing become
|4||Before replenishing the grease, the grease nipple shall be wiped
clean and the cover plate for oil drainage shall be opened,
restored and locked tightly until the cleaning is finished.|
|5||Mixed use of different kinds of grease is strictly forbidden.|
|6||The pressing quality of the grease is determined by the time when
the old grease is fully drained off and the drainage of new oil is
|7||When replenishing the grease, bearing temperature will rise
temporarily and restore to a normal temperature. The external
temperature rise of the bearing bracket is determined by 40 ℃
(environmental temperature 40℃) and the highest temperature shall
not exceed 80℃.|
2. Running Inspection
When the running is started, running diaries shall be kept
according to following matters and any abnormalities occur shall be
handled as early as possible.
|1||Temperature: please note if there is great variation on
|2||Sound: the sound will appear to some extent if the bearing is in a
normal running state, please do not worry if three is no severe
change or special shrill sound.|
