Therefore, according to the utility model discloses operating mechanism 1 can prevent effectively that dust sand grain from getting into the rotation region of steering rocker arm 200, and reduces unilateral wearing and tearing, has advantages such as frictional resistance is little, the atress is balanced, dustproof effectual.

In some embodiments of the present invention, as shown in fig. 3, the operating mechanism 1 further includes a stop collar 600. The retainer ring 600 is installed between the first ball bearing 300 and the second ball bearing 400, and the rotation shaft 500 is inserted into the first ball bearing 300, the retainer ring 600 and the second ball bearing 400.

The retainer ring 600 is located at the axial center of the bracket shaft hole 101, and the first ball bearing 300 and the second ball bearing 400 are symmetrically arranged at both axial sides of the retainer ring 600. The two end faces of the first ball bearing 300 respectively abut against the limiting ring 600 and the first mounting plate 210, the two end faces of the second ball bearing 400 respectively abut against the limiting ring 600 and the second mounting plate 220, and the first ball bearing 300 and the second ball bearing 400 are both stressed in a balanced manner to prevent deflection.

Specifically, the first ball bearing 300 and the second ball bearing 400 may be dust-proof ball bearings, and both end surfaces of both ends of the first ball bearing 300 and end surfaces of both ends of the second ball bearing 400 are configured with dust-proof covers.

The first ball bearing 300 and the second ball bearing 400 can prevent dust from entering the balls of the first ball bearing 300 and the second ball bearing 400 by constructing the dust covers, thereby reducing the abrasion of the first ball bearing 300 and the second ball bearing 400 and reducing the maintenance cost.

In some embodiments of the present invention, as shown in fig. 2, the bracket 100 includes a bracket mounting portion 110 and a rotating portion 120.

The outer contour of the rotating part 120 is configured to be cylindrical and is connected to the holder mounting part 110, and the holder shaft hole 101 is formed at the radial center of the rotating part 120.

The bracket mounting portion 110 is located outside the pitman arm 200, and the rotating portion 120 extends between the first mounting plate 210 and the second mounting plate 220. By configuring the rotating portion 120 to be cylindrical, it is possible to accommodate the shape between the first mounting plate 210 and the second mounting plate 220, preventing interference with the bracket 100 when the pitman arm 200 rotates relative to the bracket 100.

Further, as shown in fig. 3, a first reinforcing plate 230 and a second reinforcing plate 240 are coupled between the first mounting plate 210 and the second mounting plate 220, and the first reinforcing plate 230 and the second reinforcing plate 240 are respectively located at opposite sides of the rotation part 120.

The first reinforcing plate 230 and the second reinforcing plate 240 are matched with the first mounting plate 210 and the second mounting plate 220 to shield the rotating positions of the mounting portion 110, the first ball bearing 300, the second ball bearing 400 and the rotating shaft 500 at two opposite sides in the radial direction, so that a certain dustproof effect can be achieved. In addition, an additional reinforcing plate may be connected between the first mounting plate 210 and the second mounting plate 220 to improve structural strength between the first mounting plate 210 and the second mounting plate 220.

That is, the widths of the top and bottom portions of the first and second mounting

plates

210 and 220 are small, and the width of the middle portion is large. When the force applied to the rocker arm at the rotating shaft 500 is large, the first mounting plate 210 and the second mounting plate 220 form a wide shape at the rocker shaft hole 201, the structural strength is high, and the first mounting plate 210 and the second mounting plate 220 can cover the first ball bearing 300 and the second ball bearing 400 at the rotating shaft 500 in a large area, so that sand particles are prevented from entering the rotating shaft 500 and the first ball bearing 300 and the second ball bearing 400 to a large extent.
