Problems solved by technology

For the floating meshing driving device with spherical joints at both ends of the floating mechanism that we have adopted in the project, the setting of the wheel set is relatively complicated, and the structural size of the driving device along the direction of the rack is large, which affects the opening and closing stroke. At the same time, the rack mechanism requires It bears torsion moment and has a large cross-sectional size, so it is not suitable for the opening and closing roof projects with compact structure, high standard requirements, and exquisite appearance

Abstract

An embodiment of the invention discloses a gear and rack driving device capable of realizing floating meshing. The gear and rack driving device comprises a driving mechanism, a rack mechanism, a floating mechanism and a machine base; one end below the driving mechanism is connected with the machine base through the floating mechanism; the driving mechanism comprises a driving gear, the driving gear meshes with the rack mechanism, the driving gear floats along with the rack mechanism, and the driving gear transmits power to the rack mechanism. According to the gear and rack device capable of realizing floating meshing, a driving box acts on the rack mechanism through a wheel set, the purposes of positioning and guiding are achieved, accurate and reliable meshing between a gear and a rack is guaranteed, the floating mechanism is connected with the fixed machine base, the gear is driven to float along with the rack mechanism, thus the device adapts to large structural deformation and mounting errors, and the requirements of the position fluctuation and small-stroke lifting functions of a retractable roof are met.

Description

technical field [0001] The invention relates to the technology of driving equipment for opening and closing the roof, in particular to a floating meshing rack and pinion driving device. Background technique [0002] With the official release of the national industry standard "Technical Standards for Open and Closed Roof Structures", the application of open and close roofs in China has become increasingly widespread. The commonly used driving methods for open and close roofs are: wheel drive, hoist wire rope drive, sprocket chain drive and rack and pinion drive. Among them, the rack and pinion drive is the most widely used as a high-precision, safe and reliable drive method. Due to the large deformation and installation errors between the retractable roof and the fixed support structure, the movable roof supported by the trolley cannot guarantee the precise positional relationship with the support structure, and it is difficult to adopt a simple rack and pinion meshing struc...
