Abstract

The invention relates to a vibration technique and can be used in various industries. The aim of the invention is to simplify the design by eliminating a number of elements and improving reliability by better circulating a liquid lubricant. The vibration exciter comprises a housing 1 with covers .2 and a crankcase 3. Shaft 4 and bearings 5 are placed in housing 1. Debalance 6 is fixed on shaft 4. Shaft 4 is made hollow with sloped angles to its axis by channels 7, designed to supply oil to bearings 5 of the shaft cavity 8 4. The unbalance 6 has recesses 9 on each of its end surfaces and radial channels 10, which connect the cavity of the recesses 9 with the cavity of the crankcase 3. The cavity 8 of the shaft 4 and the cavity of the crankcase 3 are designed to connect to tank II, and The axial section along the shaft 8 of the shaft 4 consists of two trapeziums, the larger base of which is combined with the axis of the shaft 4. 2 Il.

The vibration exciter comprises a housing 1 with 2, a crankcase 3, a shaft 4 placed in the housing 1 and sub-holders 5, and an imbalance 6 fixed on the shaft 4. The shaft 4 is hollow with inclined channels 7, made at an angle to its axis and intended for supply oils to subdivision- iinKa.vi 5 from the cavity 8 of the shaft 4, and the axial section of the cavity 8 of the shaft 4 consists of two trapeziums, most of which base is aligned with the axis of the shaft 4.

Unbalance shaft 4 is driven from a drive (not shown), driven by

hesitation. The oil from the tank 11 through the sleeve 12 through the tube 13 by gravity into the cavity 8 of the shaft 4. Under the action of centrifugal forces, the oil from the cavity 8 through the channels 7 enters the bearings 5, ensuring their lubrication and cooling. Next, the oil from the stack of sub-bearings 5 enters the recesses 9 on the end surfaces of the unbalance 6 and through the channels 10 into the cavity of the crankcase 3, from where it is pumped due to the air flow from the rotation of the unbalance 6 through the channel 14, sleeve 12 into the tank I. the oil is circulated safely in the exciter.
