Embodiment Construction

[0024] The eccentric block used for the vibration motor provided by the present invention is that the clamping device of the eccentric block is arranged above the periphery of the eccentric block, so that the distance between the fastening bolt and the axis point of the shaft is closer, the force arm is shorter, and the clamping is more accurate. firm. There is a stress groove at the connection between the eccentric block and the eccentric block, so that more parts of the eccentric block will participate in the deformation during the clamping process, and at the same time, the overall deformation of the eccentric block's peripheral part will be uniform, so that the clamping force between the eccentric block and the rotating shaft is evenly distributed. , so that the clamping device of the eccentric block is firm and reliable.

[0025] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention i...

Abstract

The invention provides an eccentric block for a vibration motor. The eccentric block is composed of an eccentric block body (1), an eccentric block periphery (3) and a peripheral clamping device (6) which are arranged on the same plane. The eccentric block periphery (3) is arranged in the middle of the eccentric block body (1), stress grooves (2) are formed in the connection positions of the eccentric block periphery (3) and the eccentric block body (1), and a rotating shaft hole (7) is formed between the eccentric block periphery (3) and the eccentric block body (1). The peripheral clamping device (6) is arranged on the eccentric block periphery (3), and the peripheral clamping device is provided with an opening groove (5) and a fastening bolt hole (4) which is in perpendicular intersection with the opening groove.

Description

technical field [0001] The invention relates to an eccentric mass, in particular to an eccentric mass for a vibrating motor. Background technique [0002] The clamping device of the eccentric block of the vibration motor is generally slotted on the side of the eccentric block, and then tightened and clamped with bolts, or the eccentric block is fixed by a closed structure using a keyway and a key connection. The disadvantage of the former is that the shaft hole of the eccentric block deforms unevenly during the clamping process, resulting in more force on one side and less force on the other side. After the vibration motor runs for a long time, the bolts will vibrate loose and affect safety performance; The latter uses the method of cooperating and fixing the keyway and the key. There is a gap between the keyway and the key. There will be noise after the vibration motor runs at high speed, and the excitation force of the eccentric block fixed with the keyway is fixed, and th...
