A dial gauge, also known as a dial indicator, is a precision measuring instrument used to measure small linear distances. Its construction involves several key components that work together to display the measurement on a dial face. Based on the provided reference, the specific parts of a dial gauge include components visible on the exterior and internal gear mechanisms.
Here is a breakdown of the parts listed in the reference:
Key Components of a Dial Gauge
The dial gauge is composed of various parts, from the protective outer shell to the intricate internal gears. Understanding these components is essential for appreciating how the gauge functions.
The parts listed in the reference are:
- Crystal (01): The transparent cover protecting the dial face and pointer.
- Bezel (02): The ring around the crystal, often rotatable to set the zero point.
- Pointer (03): The main hand that rotates around the dial to indicate the measurement.
- Outer Dial (04): The stationary or rotatable plate marked with measurement graduations.
- Hand (05): Refers to the pointer or a smaller hand indicating revolutions (not explicitly detailed if separate from 'Pointer' in this context but listed as 'Hand').
In addition to these external and visible parts, the reference also lists internal mechanical components crucial for the gauge's operation:
- 120Z Main Gear Assy (with 16Z Pinion): A primary gear assembly driving the pointer.
- 12Z Pinion: A smaller gear involved in the gear train.
- 120Z Idle Gear Assy (with Hair Spring): Another gear assembly, potentially linked to the return mechanism or smoothing movement.
- Upper Metal (with Jewel): A part of the internal mechanism, likely supporting a shaft or pivot, possibly utilizing a jewel bearing for reduced friction.
- Wire Spring for Bezel: A spring used to provide tension or secure the bezel.
For a clearer view, here's a table summarizing the parts from the reference:
| Reference Code | Part Name | Notes/Description from Reference |
|---|---|---|
| 01 | Crystal | |
| 02 | Bezel | |
| 03 | Pointer | |
| 04 | Outer Dial | |
| 05 | Hand | |
| 120Z Main Gear Assy (with 16Z Pinion) | ||
| 12Z Pinion | ||
| 120Z Idle Gear Assy (with Hair Spring) | ||
| * Upper Metal (with Jewel) | ||
| Wire Spring for Bezel |
These components work in concert to translate the linear movement of the gauge's spindle into the rotational movement of the pointer on the dial, allowing for precise measurement readings.
