Abstract
A rotational saw bow device without a rotary axis includes a saw bow seat, a fixed portion and a rotating device. The fixed portion is connected to the saw bow seat. The rotating device is disposed between the saw bow seat and the fixed portion, and the rotating device includes a driving component, an angle adjustment portion, a trajectory portion and a rotating mechanism. The driving component drives a gear wheel portion to rotate on the angle adjustment portion, so that the rotating mechanism moves along the trajectory portion to rotate the saw bow seat. In addition, a sawing machine includes the rotational saw bow device.

A rotational saw bow device, comprising:
- a saw bow seat;
- a fixed portion, the fixed portion connected to the saw how seat;
- and
- a rotating device, the rotating device disposed at a position between the saw bow seat and the fixed portion, the rotating device comprising:
- an angle adjustment portion,
- a driving component including a gear wheel portion mated to the angle adjustment portion,
- a trajectory portion, and
- at least one rotating mechanism, wherein the driving component drives the gear wheel portion to rotate on the angle adjustment portion causing the at least one rotating mechanism and the saw bow seat to move together along the trajectory portion;
- wherein the at least one rotating mechanism includes an outer mounting panel and an inner mounting panel, the outer mounting panel and the inner mounting panel are rigidly connected to the saw bow seat and engage opposing sides of the trajectory portion;
- and
- wherein each of the outer mounting panel and the inner mounting panel comprises:
- a respective slot;
- a plurality of first follower bearings positioned at a periphery of the respective slot and engaging a first side of the opposing sides of the trajectory portion,
- a plurality of second follower bearings positioned at the periphery of the respective slot and engaging a second side of the opposing sides of the trajectory portion opposite the first side, and
- at least one third follower bearing positioned in the respective slot between the plurality of first follower bearings and the plurality of second follower bearings and engaging a third side of the trajectory portion orthogonally to the first side, the second side, the plurality of first follower bearings, and the plurality of second follower bearings.
