A sealing component is provided on the upper surface of the potting base 1. A potting tube 7 is inserted into the spindle 2. A bottom flow channel 22 is opened at the bottom of the spindle 2.

[0028] The upper surface edge of the potting base 1 is provided with a threaded hole 103 that mates with the second bolt 4.

[0029] The energy storage flywheel assembly 8 has a through hole that mates with the second bolt 4.

[0030] In use, the second bolt 4 passes through the through hole and threaded hole 103 of the energy storage flywheel assembly 8 to fix the potting base 1 and the energy storage flywheel assembly 8 in place.

[0031] The potting base 1 has a first groove 101 arranged coaxially, and a second groove 102 arranged coaxially is formed on the bottom surface of the first groove 101.

[0032] The bottom surface of the second groove 102 is provided with a plurality of countersunk holes 1021 arranged around the center line of the potting base 1, and the first bolt 3 is installed in the countersunk holes 1021.

[0033] During use, the first bolt 3 passes through the through hole of the potting base 1 and is fixedly connected to the mandrel 2.
