Abstract

The invention provides a leveling supporting leg based on a planetary roller screw. The planetary roller screw is a transmission device for converting the rotation of an external motor to linear reciprocating motion of a push rod and meanwhile converting input torque to output axial force of the push rod. The planetary roller screw comprises a nut, a plurality of rollers, a screw rod, inner tooth rings, a PTFE sealing element and an end retainer. The screw rod and the nut are coaxially mounted, the multiple rollers are uniformly arranged between the screw rod and the nut, the screw threads of the rollers make contact with the screw thread of the nut and the screw thread of the screw rod at the same time, tooth wheels of the two ends of the rollers are engaged with the inner tooth rings, the rollers perform planetary motion around the screw rod, and meanwhile, the nut is pushed to perform reciprocating motion along the axis of the screw rod. The nut and the push rod are fastened together through screws, an external spline of the external circle of the nut is matched with an internal spline of a guiding sleeve, and the nut drives the push rod to perform linear reciprocating motion. Compared with existing hydraulic leveling devices, the leveling supporting leg based on the planetary roller screw has the advantages of being high in bearing capacity, high in response speed, high in leveling precision, long in service life, convenient to maintain and the like.

Description

Technical field [0001] The invention relates to a leveling support leg based on a planetary roller screw, belonging to the technical field of planetary roller screws. Background technique [0002] Due to the rapid development of military reconnaissance technology and the continuous improvement of air-to-ground strike capabilities, ground weapon vehicles are required to have strong maneuverability and high-response launch capabilities to avoid aerial reconnaissance and strikes and complete weapon launch tasks. Therefore, the design of high-speed, high-precision and high-reliability leveling support mechanism has become one of the key technologies of vehicle-mounted weapon systems. Generally speaking, the vehicle leveling time accounts for about one-third of the in-position time of the entire vehicle-mounted weapon system. Since the leveling support process is a very important and time-consuming link in the installation of the weapon vehicle, it has an impact on the performance of ...
