Problems solved by technology

From the point of view of the transmission principle, the cone tops of the bevel gear pair must overlap, otherwise the unbalanced load and jamming will occur, so an adjustment device is required in the actual assembly; from the support point of view, the meshing bevel gear pair has an axial load, so The support structure is more complex
At the same time, the conical top of the bevel gear pair and the inflection point of the eccentric lever must coincide and the coincident point must be located on the revolution axis. Therefore, it is quite complicated to design, manufacture and assemble the three-point coincidence of the three-dimensional space and to be located on the revolution axis.

Embodiment 1

[0020] Such as figure 1 As shown, the steering gear swing mechanism with face gear transmission in this embodiment includes a driving part 1, and an oblique penetration hole 1-1 is set on the driving component 1, and in the oblique penetration hole 1-1 An eccentric lever 2 is inserted in the 1. The part of the eccentric lever 2 is located in the oblique penetration hole 1 - 1 , and the other part of the eccentric lever 2 is located outside the driving part 1 . The input end of the eccentric lever 2 is fixedly connected with a straight involute spur gear 3 . The spur gear 3 and the face gear 4 mesh with each other. A sleeve 5 is placed outside the driving part 1 , and the face gear 4 is fixedly connected to one end surface of the sleeve 5 .

[0021] An eccentric lever support bearing 6 is arranged between the eccentric lever 2 and the drive part 1 ; a drive part support bearing 7 is arranged between the drive part 1 and the sleeve 5 .

Embodiment 2

[0025] The steering gear swing mechanism with face gear transmission in this embodiment is roughly the same as the steering gear swing mechanism with face gear drive in Embodiment 1, the difference lies in the power input mechanism.

[0026] The power input mechanism 9 in this embodiment includes a power input shaft 9-1, a cycloidal pinwheel reduction transmission mechanism 9-2 and a drive component connecting shaft 9-3. The power input shaft 9-1 is connected with the cycloidal pinwheel reduction transmission mechanism 9-2, and the driving component connecting shaft 9-3 is connected with the cycloidal pinwheel reduction transmission mechanism 9-2 and the driving component 1.

Abstract

The invention discloses a steering engine swing mechanism with face gear transmission, which has good transmission performance and simple structure. The steering engine swing mechanism comprises a power input mechanism, a drive mechanism and an eccentric lever, wherein the power input mechanism is connected with the drive mechanism; the eccentric lever is connected with the drive mechanism; the input end of the eccentric lever is fixedly connected with a straight-tooth involute cylindrical gear; and the straight-tooth involute cylindrical gear is meshed with a face gear.

Description

technical field [0001] The invention relates to a steering gear swing mechanism, in particular to a steering gear swing mechanism with face gear transmission. Background technique [0002] Steering gear is a key component of rockets, missiles, ships and ship rudder swing mechanisms. In order to meet the needs of increasing carrying capacity, there is an urgent need for actuators that are limited in design space and require small power input and high torque output. [0003] Theoretical results show that the use of eccentric levers to drive the steering gear to swing can realize the function of small power input and large torque output, which has obvious advantages in occasions where the design space is limited and high torque output is required. The existing transmission mechanism that utilizes the eccentric lever to realize the swing of the steering gear is a bevel gear pair transmission mechanism. The eccentric lever is a folding rod, and one end is the input end of the e...
