[0010] Furthermore, the guiding mechanism also includes a polytetrafluoroethylene (PTFE) bushing, which is mounted on a metal ring and slides with the guide rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This feed device for tapered roller machining has the following advantages:

[0012] 1. The telescopic protective sleeve is made of stainless steel corrugated pipe, which can extend and retract synchronously with the movement of the transmission seat, completely enclosing the lead screw and preventing iron filings, coolant, etc. from entering the mating surface between the lead screw and the transmission seat, thereby reducing the wear rate of the lead screw, ensuring its transmission accuracy, and extending its service life.

[0013] 2. The telescopic protective sleeve is connected to the frame through a guide mechanism to limit the radial runout of the telescopic protective sleeve and ensure its concentricity with the lead screw, thereby avoiding additional stress on the lead screw by the telescopic protective sleeve and ensuring the smoothness of transmission.

[0021] The telescopic protective sleeve 8 is made of stainless steel corrugated pipe with a thickness of 0.1-0.3mm. It has good extensibility and fatigue resistance. It can extend and retract synchronously with the movement of the transmission seat 5, completely covering the lead screw 9, preventing iron filings, coolant and other substances from entering the mating surface between the lead screw 9 and the transmission seat 5, thereby reducing the wear rate of the lead screw 9, ensuring its transmission accuracy and extending its service life.

[0022] It also includes a sealing ring 10, which is installed at the connection between the telescopic protective sleeve 8 and the frame 1 and at the connection between the telescopic protective sleeve 8 and the transmission seat 5. The sealing ring 10 is a fluororubber ring, which is used to enhance the sealing of the connection and effectively prevent coolant from seeping in.
