Description

Ball bowl bearing changer

This creation is about an operating device that can choose to disassemble and assemble the ball bowl bearing either electrically or manually.

At present, the common steering mechanism of the common locomotive faucet is mainly equipped with a steering device in the front of the locomotive. The steering rod of the steering device is connected to the front fork through the head tube of the frame unit, so that it can be opposed to the head tube. Turn the steering lever. For example, the patent case No. M507889 "Locomotive Steering Device" announced by the Republic of China on September 1, 104. It is disclosed that the steering device includes a steering rod passing through the head tube, an upper bead bowl set in the lower end of the head tube, a lower bead bowl set on the steering rod, and a lower bead bowl set on the steering rod.
