Force transferring connection structure of columnar component and platy component

Abstract

The invention provides a force transferring connection structure of a columnar component and a platy component. The platy component is provided with first countersunk groove tables, the columnar component is provided with second countersunk groove tables, first fixing holes and second fixing holes are formed in the first countersunk groove tables and the second countersunk groove tables respectively, the first countersunk groove tables and the second countersunk groove tables form blind holes with the circular cross sections, and the inner walls of the blind holes are matched with the outer walls of circular keys; the circular keys are arranged in the first countersunk groove tables and the second countersunk groove tables and connected with the first countersunk groove tables and the second countersunk groove tables through fixing parts. By adopting the structure, no protrusion is formed on the outer side end faces, the circular key structures are adopted, the outer walls of the circular keys and the inner walls of the first countersunk groove tables and the second countersunk groove tables are taken as torque transmission structures, the matching area is large, the positioning clearance is small, and the borne extrusion force and shear force are high. Due to the fact that the shearing resistance is high, the torque transmission reliability can be guaranteed without the large thickness. Tests show that the force transferring connection structure can reliably transmit the torque both in a vertical state and a lodging state.

Description

technical field [0001] The invention relates to the field of transmission structures, in particular to a force transmission connection structure of columnar and plate-shaped components. Background technique [0002] In the connection structure between the shaft and the lug, flat plate or fork plate, there are two types. One is to prevent the shaft from moving axially, the shaft and the lug can rotate and play a connecting role. It is enough to set the pin hole and the baffle plate to limit the axial position. The connection structure in this application refers to the connection to prevent the shaft from moving in series and achieve the effect of torque transmission, mainly to ensure the fixation between the shaft and the plate-shaped member. Generally speaking, this place refers to the low-speed rotation, lugs and shafts, which are equipped with power drive wheels, such as worm gears, gears, etc., and rotate together relative to the support and fixed seat, usually with a ro...

Problems solved by technology

The 2nd and 3rd structure processing is more troublesome, and the tolerance is not easy to guarantee, and the 3rd structure cannot be implemented under the condition of smaller diameter

The first and second connection structures above need to have a thicker thickness at the transmission part in order to transmit torque better, which increases the size of the entire structure
