[0006] Further, two oil leakage prevention rings are arranged in the bearing positioning sleeve, and the two oil leakage prevention rings are arranged opposite to each other, one of which abuts against the surface of the fixed bearing, and the other of which abuts against the surface of the movable bearing.

[0007] Further, the shaft end connecting seat includes a mounting portion and a connecting portion, a plurality of mounting holes are provided on the mounting portion, and bolts pass through the mounting holes to fixedly install the shaft end connecting seat on the end surface of the degree of freedom rotating end, and the surface of the connecting portion is provided with a threaded structure.

[0008] The utility model also provides a kind of baking oven.

[0009] A kind of baking oven, including dynamic decoupling type pipe connectors for baking oven, oven cover and oven body, dynamic decoupling type pipe connectors for baking oven is arranged between oven cover and oven body.

[0010] Further, the pie oven dynamic decoupling type pipe connector is provided with two, one is arranged at the oven cover interface end, and the other is arranged at the oven body interface end, and the two pie oven dynamic decoupling type pipe connectors are connected through a gas conveying pipe.

[0011] Further, the gas conveying pipe is a stainless steel corrugated pipe.

[0012] Further, the surface of the gas conveying pipe is further covered with a rubber heat insulation protective sleeve.

[0013] The pie oven dynamic decoupling type pipe connector has the advantages that:

[0014] 1. Dynamic and static separation rotating structure, double bearing linkage system (fixed end combined with free degree rotating end) is adopted to establish axial / radial displacement compensation channel.

[0015] 2. Double dynamic sealing system, internal integrated stepped oil seal assembly, multi-stage interception, pressure balance are realized.

[0016] 3. Double bearing structure is adopted, which can effectively reduce the friction coefficient and reduce the torsion caused by the rotating oven cover to the conveying pipe.

[0017] 4. Anti-displacement damage: reducing the direct impact of the pot cover displacement on the pipeline, prolonging the service life of the pipeline. Reliable sealing: double oil seal design effectively prevents gas leakage and adapts to high temperature and high pressure environment. Low friction operation: bearing structure reduces rotation resistance and avoids jamming or abnormal wear. Convenient installation: modular design, suitable for various pipeline sizes, without the need to modify the original equipment. BRIEF DESCRIPTION OF DRAWINGS
