detailed description

The present invention will be further described below in conjunction with specific embodiments.

A tensioning pulley of a gantry type multi-group wire saw machine as shown in Fig. 1 and Fig. 2 includes a support plate 1 and a wheel disc 2, and the wheel disc 2 is operated by a shaft 3 with a deep groove ball bearing 6 inside. Circumferential rotation, the axial end of the shaft 3 is the inner end fixedly connected to the support plate 1, the inner sealing cover 10 is fixedly installed on the inner end of the shaft 3, and the inner disc surface of the wheel disc 2 is installed with an annular jacket Plate 4, the outer cover plate 4 includes an annular protruding portion on the panel, the protruding portion is installed between the outer ring of the deep groove ball bearing 6 and the wheel disc 2, and the outer edge circumference of the outer cover plate 4 is fixedly connected On the wheel disc 2, the outer edge of the inner sealing cover 10 is covered by the inner edge circumference of the outer outer plate 4; the center of the outer end of the shaft 3 is provided with an open groove, and is arranged on the wheel disc 2 The outer sealing cover 5 on the outer surface is sealed; the inside of the tank body is respectively provided with an axial restraint block 9, two thrust ball bearings 8, and an axial retaining ring 7, and the axial restraint block 9 is axially installed in the tank body , the thrust ball bearing 8 is installed centripetally on the outer ring of the axial constraint block 9, and the axial retaining ring 7 is installed between the two thrust ball bearings 8; the outer edge circumference of the outer sealing cover 5 is fixed on On the protruding part of the outer shell plate 4, the center is compressed and fixed on the axial constraint block 9.
