Regarding the R107-DV132M4-47.63-M1 gear reducer you are asking about, the oil level mark (oil mark) is usually designed on the side or bottom of the reducer case to visually monitor the lubricating oil level.
According to the general design standards of this series (R series helical gear hardened surface reducer), the specific form and characteristics of its oil level mark are as follows:
1. Physical form of the logo
For reducers of this size R107, the oil level mark usually has the following two common forms:
(1) Round oil glass (oil sight glass):
This is the most common form. It is a circular transparent window (usually made of acrylic or glass) embedded in the side of the box, with a metal or plastic protective cover on the outside.
Scale lines: There are usually two obvious scale lines (or red dots/dimples) on the lens.
Upper limit (Max): Indicates the highest oil level.
Lower limit (Min): Indicates the lowest oil level.
Normal condition: The lubricating oil level should be maintained between the two scale lines.
(2) Oil plug/dipstick (some old-fashioned or customized models):
Located on the side of the box is a hexagonal screw plug.
During inspection, you need to unscrew the screw plug and observe the oil stains on the threads or the attached rod to determine the oil level.
2. Analyze based on your model
Your model number R107-DV132M4-47.63-M1 contains the following key information to help you locate the marking:
R107: The representative frame number is 107, which is a medium-sized reducer. Most reducers of this size are equipped with a round oil mirror, because the oil mirror is more convenient for daily inspection than the oil dipstick.
M1: The representative installation form is foot installation (horizontal).
Position judgment: In the M1 installation posture, the oil mirror is usually located on the side of the box opposite the motor, or at one end of the side of the box close to the output shaft, with a height approximately lower than the middle of the box height.
3. How to correctly view and maintain
To ensure that the reducer is operating properly, please follow these steps to check:
(1) Keep it horizontal: Make sure the reducer is installed horizontally (M1 posture).
(2) Shutdown inspection: It is recommended to check after the reducer stops running and the oil has settled, or to observe through the oil mirror after the operation is stable (depending on the manufacturer"s instructions, usually static observation is more accurate).
(3) Liquid level standard:
Normal: The oil level is near the center line of the oil mirror, or between the upper and lower scale lines.
Lack of oil: If the oil level cannot be seen, the same type of gear oil must be replenished immediately.
Too much oil: If the oil level completely submerges the oil mirror or even overflows, it will cause the oil temperature to be too high or the seal to leak.
