Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1, fig. 2, fig. 3 and fig. 4 in combination, wherein fig. 1 is a schematic structural diagram of a split floating oil seal according to a preferred embodiment of the present invention; FIG. 2 is a schematic view of the disassembled structure shown in FIG. 1; FIG. 3 is a cross-sectional schematic view of the floating platform of FIG. 1; fig. 4 is a schematic cross-sectional view of the floating ring shown in fig. 1, and a split type floating oil seal includes: floating seat 1, first mounting groove 2 has all been seted up at floating seat 1's upper and lower both ends, sealing washer 3 is all installed through 2 blocks of first mounting groove in floating seat 1's upper and lower both ends, floating ring 4 is installed to the equal block in outside of two sealing washers 3, all be equipped with second mounting groove 5 between two floating ring 4 and two sealing washers 3, through floating ring 4, the block installation between sealing washer 3 and the floating seat 1, be convenient for install and dismantle the floating oil blanket, split type improvement the practicality.

Floating seat 1 includes first stratum basale 11, the outside laminating of first stratum basale 11 has quenching layer 12, the outside laminating of quenching layer 12 has first wearing layer 13, quenching layer 12 has improved the high temperature resistance of floating seat 1, make the floating oil seal can work under the environment of high temperature, first wearing layer 13 is located the inside of first mounting groove 2, the loss that produces when having reduced sealing washer 3 and the friction of first mounting groove 2, the life of floating oil seal has been improved.

The first substrate layer 11 is made of bearing steel, the strength of the bearing steel is high, and the floating seat 1 is more stable when in use.
