Detailed Description
The utility model will be further described in detail with reference to the following examples:
the bar cooling bed turbine box sealing device shown in fig. 2 mainly comprises a bearing gland 1, a sealing ring 2 and a split gland 3, wherein the bearing gland 1 is sleeved on a transmission shaft 5 of the turbine box and is fixedly connected with a turbine box shell 8 through a plurality of first screws 7, one end, extending out of the bearing gland 1, of the transmission shaft 5 is connected with a coupler 4, and a certain distance is reserved between the coupler 4 and the bearing gland 1. An outer groove for placing the sealing ring 2 is formed in the outer side of the bearing gland 1, and the notch of the outer groove faces the direction of the coupler 4. Two sealing rings 2 are placed in the outer groove, the sealing rings 2 are sleeved on the transmission shaft 5, and the sealing rings 2 are split sealing rings, namely, one part of the sealing rings 2 in the circumferential direction is split. The bearing gland 1 is provided with a radial flange 1-1 in clearance fit with the transmission shaft 5, one end surface of the radial flange 1-1 is abutted against the shoulder, and the other end surface is used as the inner bottom surface of the outer groove and abutted against the sealing ring 2. In order to compress the sealing ring 2 and prevent the sealing ring 2 from rotating along with the transmission shaft 5, the transmission shaft 5 is further sleeved with a split gland 3, the split gland 3 is a cover body formed by two symmetrical halves, the split gland 3 is fixedly connected to the outer end face of the bearing gland 1 through a plurality of second screws 6, and the second screws 6 are connected to the axially thickest part of the bearing gland 1, so that the connection reliability can be improved; for the convenience of disassembly and assembly, the second screw 6 is arranged in a staggered mode with the coupler 4.
