Notes
- Above values are standard specifications for z=20 teeth; other tooth counts can be calculated using formulas
- Reference diameter D0 = z x m / cos(alpha)
- Outside diameter DK = D0 + 2m
Lubricating Pinion
Felt lubricating pinion can be used to lubricate the rack. Grease can be manually replenished or connected to an automatic lubrication system.
Pinion Hub for Lubricating Pinion
The hub is used in conjunction with the lubricating pinion. Lubricating oil can be channeled through special passages in the hub to the felt pinion.
Assembly Fixture for BZ Systems
The assembly fixture is used for aligning butt-jointed BZ guide rails. It includes a rack segment designed to engage with the racks on both sides of the joint for precise alignment.
Lubrication Options
| Code | Type | Description | Application |
|---|---|---|---|
| LN | Oil Protection | Light oil protection | Systems with continuous oil supply after installation |
| LG | Grease Protection | Light grease coating | Systems with continuous grease supply after installation |
| LV | Standard Grease | Full grease fill | General applications with manual lubrication |
| LO | Oil Lubrication | For centralized lubrication systems | Automatic lubrication systems |
Rack Lubrication Recommendations
- Preferred Method: Use lubricating pinion (BZR-xx-L) to automatically replenish grease to the rack
- Alternative Method: Periodic manual application of rack lubrication grease
- Recommended Lubricant: Kluber Microlube GL 261 or equivalent
- Lubrication Frequency: Adjust based on usage frequency and environmental conditions; generally recommended every 500 km travel or monthly
Selection Notes
- Drive pinion should be selected based on torque requirements and travel precision needs
- Higher tooth count results in longer travel per revolution, but also higher maximum transmissible torque
- Recommend using one lubricating pinion together with one drive pinion
- For high-speed applications, oil lubrication (LO) is recommended
- Additional sealing accessories recommended for dusty environments
- Accessories must be selected according to corresponding size specifications
