Flywheel disc expansion core tool

Abstract

The invention discloses a flywheel disc expansion core tool and relates to the technical field of flywheel disc testing. The flywheel disc expansion core tool comprises a base, a transmission base anda transmission mechanism, wherein placement sliding rails are arranged at two sides of the upper end of the base; a limiting stop block is fixed at the rear end of each placement sliding rail; a placement sliding block is connected to the upper end of each placement sliding rail; fastening knobs are arranged at two sides of the upper end of each placement sliding block in a penetrating manner; the transmission base is arranged in the centers of the upper ends of the placement sliding blocks; and a limiting sliding groove is formed in the inner side of the upper end of the transmission base. According to the flywheel disc expansion core tool, a driven gear fixed at the outer side of a rotary drum is matched with a driving gear arranged at the upper end of a servo motor, so that the rotarydrum achieves a rotating effect through the rotation between the gears, a bearing plate fixed at the upper end is driven to rotate, dynamic balance testing of a flywheel disc main body arranged at theupper end of the bearing plate is realized, the rotating stability and smoothness of the bearing plate can be ensured through gear transmission, and the situation that the bearing plate is stuck in the actual testing process and the test result is influenced is avoided.

Description

technical field [0001] The invention relates to the technical field of flywheel disk testing, in particular to a flywheel disk expansion core tooling. Background technique [0002] Flywheel, a disk-shaped part with a high moment of inertia, acts like an energy store. For a four-stroke engine, work is done every four piston strokes, that is, only the power stroke does work, and the three strokes of exhaust, intake and compression all consume work. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft, and the finished flywheel disc needs to be tested, and a clamping tool is required for the test process. [0003] The flywheel clamping tooling on the market is not convenient for placing and fixing the flywheel, and the fixing process is cumbersome. It cannot ensure that the outer circle of the flywheel to be concentric with t...
