Detailed Description

The following will combine the drawings of the embodiments of the present invention to further describe the technical solution of the present invention, and the present invention is not limited to the following specific embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 6, an exciter holder 300 includes: two bearing seat 300 plates 100, two eccentric shafts 200 and a plurality of connecting pieces 400, wherein each bearing seat 300 plate 100 is provided with two positioning grooves 110, the bottom of each positioning groove 110 is provided with a mounting hole 120, and a bearing seat 300 is provided in each of the positioning grooves 110, the bearing seat 300 has a protrusion 310, the protrusion 310 abuts against an inner sidewall of one of the mounting holes 120, a through hole 320 is formed on each of the bearing seats 300, the through holes 320 penetrate through the protruding portion 310, one end of each eccentric shaft 200 is connected to an inner side wall of a bearing 900, an outer side wall of each bearing 900 is connected to an inner side wall of one through hole 320, a plurality of first matching holes 111 are further formed at the bottom of each positioning groove 110, a plurality of second matching holes 301 are formed in each bearing seat 300, and each connecting piece 400 is movably arranged in one first matching hole 111 and one second matching hole 301 in a penetrating manner.

Specifically, one bearing housing 300 plate 100 is located at one end of two eccentric shafts 200, the other bearing housing 300 plate 100 is located at the other end of two eccentric shafts 200, and the two eccentric shafts 200 are arranged in parallel, that is, two positioning slots 110 formed on each bearing housing 300 plate 100 are located on the same horizontal plane. By mounting each bearing housing 300 on the plate 100 of the bearing housing 300, i.e. by abutting the protruding portion 310 of the bearing housing 300 against the inner side wall of the mounting hole 120 formed at the bottom of the positioning groove 110, the side of the bearing housing 300 having the protruding portion 310 abuts against the bottom of the positioning groove 110. Further, by using a plurality of connecting members 400, and each connecting member 400 is inserted into a first fitting hole 111 and a second fitting hole 301, further, each of the bearing housings 300 is connected to the plate 100 of the bearing housing 300 by bolts, so that each of the bearing housings 300 is well fixed in the positioning groove 110.
