The gear and rack transmission mechanism comprises a base, a rack, a gear and a limiting jaw, wherein the gear and the limiting jaw are arranged on the base, the gear is rotatably connected with the base, a limiting plate is arranged on the rack meshed with the gear, a wear-resistant block is arranged on the limiting jaw, and the limiting plate is in sliding fit with the wear-resistant block.
Description
Technical Field
The utility model relates to a rack and pinion drive mechanism belongs to mechanical transmission technical field.
Background
The rack and pinion transmission has a wide application in industry, the rotation of a gear is converted into a gear tangential force to be transmitted to a rack, meanwhile, the radial force of the gear generated by meshing needs to be born by an external relative motion part, and under the conditions of heavy load and limited space, how to design a rack and pinion transmission mechanism only transmitting the gear tangential force is a technical problem to be solved by a person skilled in the art.
Disclosure of Invention
To the above problem, the utility model provides a only transmit rack and pinion drive mechanism of gear tangential force.
In order to achieve the above object, the utility model adopts the following technical scheme: the gear and rack transmission mechanism comprises a base, a rack, a gear and a limiting jaw, wherein the gear and the limiting jaw are arranged on the base, the gear is rotatably connected with the base, a limiting plate is arranged on the rack meshed with the gear, a wear-resistant block is arranged on the limiting jaw, and the limiting plate is in sliding fit with the wear-resistant block.
Two limiting clamping jaws are provided.
Beneficial effects of the utility model
The utility model discloses a gear and spacing jack catch setting are on the base, and wear-resisting piece is installed to spacing jack catch front end, install on the rack at the rack limiting plate, and at gear and rack operation in-process, wear-resisting piece contacts with the limiting plate of rack to relative slip, the limiting rack is at the radial removal of gear, guarantees not outwards transmission of the radial force that the meshing in-process produced when effectively transmitting gear tangential force.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a base 1, spacing jack catch 6, gear 2, rack 3, limiting plate 4 and wear-resisting piece 5. Two spacing jack catchs 6 are fixed on base 1, and gear 2 pivoted sets up on base 1, and gear 2 meshes with rack 3, and limiting plate 4 is fixed with rack 3, and wear-resisting piece 5 is fixed on spacing jack catch 6, and wear-resisting piece 5 and limiting plate 4 sliding fit. At gear 2 and 3 operation in-process of rack, limiting plate 4 and the contact of wear-resisting piece 5 to relative slip, wear-resisting piece 5 has restricted rack 2 at the radial removal of gear 3, guarantees when effective transmission gear 2 tangential force that the radial force that the meshing in-process produced does not to the utility model discloses outer transmission.
