Handle and Pin Interface Detail

Pull out the positioning pin to turn the handle, that is, the worm gear and worm separation can be realized, and the pneumatic drive device can be operated.

SLA series gearbox connection: the bottom flange of the gearbox is connected with the upper flange of the pneumatic drive device, the spline shaft is mounted with the axle hole of the pneumatic drive device, and the flange bolts are tightened.

Storage Requirements

1. Short-term storage (less than 6 months)

The storage environment should be as far as possible to avoid high temperature, humidity and dust content of the environment storage. Gear boxes should be stored in wooden pallets or wooden cases. Suitable anti-rust oil must be applied to the input shaft, installation flange, valve shaft installation hole and hand wheel hole of the gearbox.

2. Long-term storage (more than 6 months)

The storage conditions shall be the same as Clause 1. However, it should be noted that long-term storage should be inspected frequently to check the protection condition. If signs of rust are found, all the products in stock should be re-protected immediately.

Frequently Asked Questions

How is manual operation achieved on the SLA series gearbox?
You can easily operate the valve manually by turning the hand wheel or the input shaft to open or close it.
How do you separate the worm gear for pneumatic drive operation?
Simply pull out the positioning pin to turn the handle. This operation realizes the separation of the worm gear and the worm, allowing the pneumatic drive device to run.
What materials are the primary components of the gearbox made of?
The gearbox utilizes high-grade materials: the Handwheel is made of Q235A, the Housing and Cover are QT450-10, the Worm Gear is QT500-7, the Worm Shaft is 45 carbon steel, and the Indicator is HT250.
How should the gearbox be connected to a pneumatic drive device?
Connect the bottom flange of the gearbox with the upper flange of the pneumatic drive device. Mount the spline shaft into the axle hole of the pneumatic drive device, and then firmly tighten the flange bolts.
What are the environmental requirements for storing the gearboxes?
For both short and long-term storage, avoid high temperatures, humidity, and high dust content. Place them on wooden pallets or in wooden cases, and apply suitable anti-rust oil to critical interfaces like the input shaft and installation flanges.
What maintenance is required during long-term storage exceeding 6 months?
Products stored for more than 6 months require regular inspections. If any signs of surface rust are detected, the affected products must be re-protected with anti-rust oil immediately.
