Flexible Shafts

We are manufacture and supplies a wide range of Air Expanding shafts. Core holding is initiated mechanically and not pneumatically in this lug type shaft. Excellent performance is delivered even for heavy load and higher speed. Positive gripping and core centering are achieved with the help of cam/lug design. Easy handling of cores with uneven inside diameter. Key and alien cap bolt prevent any shearing of journals pipe assembly. Above price may vary as per customer requirement related to OD/ID and length etc.

What are the different places of the slat-type inflation shaft and the key-type inflation shaft?

The inflation shaft is the shaft that can be raised after the high pressure is inflated, and the shaft that can be retracted and retracted after the deflation can be divided into a slat type inflation shaft, a key strip type inflation shaft, and a convex key type gas. Upward shaft and slip type and pneumatic type, etc., have the advantages of short inflation time, simple paper tube placement, large load bearing capacity, high economic efficiency, simple maintenance and long service life. It has a variety of structural methods: surface rotation key bar / slat type; center guide key bar / slat type and independent scheduling slip type. It is widely used in paper machines, laminating machines, trademark printing machines, bag making machines and battery equipment. The air-inflating shaft is generally matched with a clamp. It is suitable for a coiled tube with a large inner diameter. It is equipped with a safety chuck, which makes the folding between the air-expansion shaft and the machine freely, saving labor, time and money.

The difference between the slat type inflation shaft and the key bar type inflation shaft:

1. Plate type air expansion shaft: It is suitable for winding high precision machinery or lighter items. Most of the expansion is the plate, the fulcrum is even and the force is even, and the general lifting height can reach 4mm to 5mm; in fact, the physical map and parameter table are as follows:


2. Key type air expansion shaft: It is suitable for items with heavy mechanical load capacity. The key type expansion shaft is a single key strip, the fulcrum is loose to each key strip, and the balance is stressed. After inflation, the unilateral expansion height can reach 5mm to 6mm. The main body of the shaft is made of high-quality steel pipe, the surface is chrome-plated, and the aluminum convex key is elastic. It is equipped with a fast filling and exhausting nozzle and a high-quality rubber liner. The sealing effect is good, the shaft head can be disassembled, and the service life is long.发送反馈
