A high-precision oiling chain for a stenter setting machine

Abstract

The invention relates to a high-precision oil filling chain for a tentering setting machine. The high-precision oil filling chain is formed by connection combination of several chain link units, each chain link comprises an upper chain sheet and a lower chain sheet, chain sheet pin holes disposed at both ends of the upper chain sheet and the lower chain sheet, deep groove ball bearings concentric with the chain sheet pin holes, and an upper dust cap and a lower dust cap disposed between the deep groove ball bearing and the upper chain sheet and the lower chain sheet, the near-outer ring surfaces of the upper dust cap and the lower dust cap are provided with cylindrical bosses, the cylindrical bosses of the upper dust cap are provided with inclined oil filling ports, the tail ends of the oil filling ports are over against the balls of the deep groove ball bearings, the chain sheet is correspondingly provided with through-holes, in which the cylindrical bosses are embedded, chain seat pin holes and the chain sheet pin holes are corresponding, and are connected by inserted pins, the deep groove ball bearings are sleeved on the pins, the upper ends of the pins are provided with clamping slots, the center of an upper flange is provided with an M8 screw hole, and a press plate is disposed, the center of the press plate is equipped with a through-hole corresponding to the M8 screw hole, a bolt is inserted into the through-hole, and is screwed into a threaded hole, and the edge of the press plate is clamped and embedded in the clamping slots.

Description

technical field [0001] The invention relates to the field of high-speed setting machines of printing and dyeing machinery, in particular to chains on the setting machines. Background technique [0002] Oil chains for stenter setting machines are conventional products. For a long time, the products of the prior art have always had the following problems: 1. The original chain seat needs to be pulled convex to ensure the length of the M8 thread, so the deformation of the A surface is large, plus the original chain seat In order to ensure sufficient strength, heat treatment is required, so there is a phenomenon that the ∅12.8 hole is not vertical up and down. [0003] 2. Since the two casings in the chain link matched with the shaft pin are connected to the chain piece by means of punching riveting, there will be a phenomenon that the two holes are not parallel. [0004] 3. The two dust-proof covers (with holes and without holes) in the chain link are prone to cracking when th...

[0002] Oil chains for stenter setting machines are conventional products. For a long time, the products of the prior art have always had the following problems: 1. The original chain seat needs to be pulled convex to ensure the length of the M8 thread, so the deformation of the A surface is large, plus the original chain seat In order to ensure sufficient strength, heat treatment is required, so there is a phenomenon that the ∅12.8 hole is not vertical up and down

[0003] 2. Since the two casings in the chain link that match the shaft pin are connected to the chain piece by means of punch riveting, there will be a phenomenon that the two holes are not parallel

[0004] 3. The two dust-proof covers (with holes and without holes) in the chain link are prone to cracking when the chain link is riveted. In addition, because the high-temperature resistant grease is injected into the deep groove ball bearing of the chain link, the grease is easy to overflow and prevent dust cover
