Description
Technical Field
The utility model relates to a printing and dyeing field especially relates to a dustproof chain.
Background
Patent No. CN208997263U discloses a dustproof chain, but in this patent dust can pile up at the bearing oil filling mouth department, and the accumulational dust can get into inside the bearing when filling grease, leads to high-speed operation to generate heat, card dead scheduling problem, influences bearing life. In addition, some special cloth materials can generate oily substances under the high-temperature working condition, and the oily substances enter the bearing to cause the overflow of high-temperature lubricating grease, so that the service life of the chain is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a four-footed machinery wooden ox gliding horse of emulation gait.
The utility model discloses an innovation point lies in the utility model discloses in can effectively block dust or oily material entering bearing oiling mouth, prolong the life of chain.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: a dustproof chain is composed of several chain units consisting of upper and lower plates, chain links consisting of upper and lower chain plates and bearing, and pin axle for linking said chain links with said chain seats, a sealing gasket is arranged between the bearing and the chain link lower chain sheet, the butterfly-shaped elastic sheet is of a hollow round table-shaped structure, the upper end of the butterfly-shaped elastic sheet is attached to the upper plate of the chain seat in a circumferential manner, the lower end of the butterfly-shaped elastic sheet is attached to the upper chain sheet of the chain link in a circumferential manner and completely covers the pin shaft hole on the upper chain sheet, the circumference of the lower end of the butterfly-shaped elastic sheet is provided with a convex plate, and a bulge inserted into the bearing oil injection port is arranged on the convex plate.
Furthermore, the free end part of the convex plate tilts towards one side of the circumference of the upper end of the butterfly-shaped elastic sheet. So that the bearing oil filling port is convenient to operate when being opened.
Furthermore, a plurality of grooves are formed in two sides of the convex plate. So that the convex plate of the butterfly-shaped elastic sheet is pushed by a tool to have a clamping point and is not easy to slip.
Further, the sealing gasket is a circular ring-shaped sealing gasket. And the loss of grease in the bearing is reduced.
The utility model has the advantages that:
1. the utility model discloses in can effectively block dust or oily material entering bearing oiling mouth, prolong the life of chain.
2. The utility model discloses well flange free end portion makes the convenient operation when opening bearing oiling mouth to chain seat upper plate department perk.
3. The utility model discloses well flange both sides all are equipped with a plurality of recesses and make the flange that promotes butterfly shell fragment with the instrument card contact point occasionally, difficult slipping.
