SU1202628A1 - Vibration exciter - Google Patents

Description

The invention relates to a machine-building and can be used in particular in balancing machines with forced vibration of balanced products.

The purpose of the invention is to expand the functionality of the vibration exciter by allowing the adjustment of the phase angle of the vibration to be excited.

The drawing shows the proposed vibration exciter.

The vibration exciter comprises a base 1, a drive shaft 2 placed thereon, an end cam 3 secured to the last one. The front cam 3 is fixed on the shaft 2 from an axial movement and is provided with elements 4-6 for reciprocating the consumer (not shown). The shape of the elements 4-6 depends on the relative position of the vibration exciter and the consumer and is not shown in the drawing. The thrust element of the exciter is made in the form of a sleeve 7, placed on the base 1 by means of a rack 8, can be rotated coaxially to the drive shaft 2, and the support roller

9, made, for example, in the form of a ball bearing and placed at the end of the sleeve 7 perpendicular to the axis of the shaft one shaft 2 and the cam 3 cooperating with the end surface of the cam 3.

Vibro works as follows.

0 Drive shaft 2 is rotatable. sweeping movement with a desired rotational speed, which is transmitted to the face cam 3, for example, by means of a slotted or keyed

15 compounds (not shown). Interacting with the support roller 9 with its face surface, the cam 3 begins to make a reciprocating motion relative to the sleeve

20 7 fixed axially in the rack 8. To change the phase angle of the reciprocating movement of the cam 3 relative to the rotational movement of the drive shaft

25.2, the sleeve 7 in the rack 8 is rotated to a predetermined angle.

The reciprocating motion of the cam 3 is transmitted by elements 4-6 to the consumer.

Claims (1)

VIBRATOR, comprising a base, a drive shaft mounted on it, a cam end mounted on the latter, and a thrust element located on the base, characterized in that, in order to expand the functionality, the thrust element is made in the form of a sleeve mounted to rotate coaxially with the drive shaft, and a support roller placed on the end face of the sleeve perpendicular to the axis of the drive shaft and interacting with the end surface of the cam.
