Embodiment 1

[0047] Embodiment 1. The countersunk head screw holes 9 are fixedly arranged on both sides of the edge of the upper pressure ring 7. The two countersunk head screw holes 9 are symmetrically arranged, and the countersunk head screw holes 9 pass through the body of the upper pressure ring 7. A through hole with internal thread; the wire hole 10 is fixedly arranged on one side of the lower pressing ring 8; the pressing screw 11 is arranged on the edges of both sides between the tapered rollers 5, and the pressing screw 11 passes through The countersunk head screw holes 9 of the upper pressure ring 7 are tightened with the screw holes 10 of the lower pressure ring 8, and a number of pressure screws 11 are arranged at equal distances in the circumferential direction between the upper pressure ring 7 and the lower pressure ring 8. The upper holding ring 1 , the lower holding ring 2 , the tapered roller 5 , the upper pressing ring 7 and the lower pressing ring 8 are connected as a who...

Embodiment 2

[0048] Embodiment 2. On the basis of the technical solution of the present invention, three to eight groups of pressing screws 11 are arranged at equal distances in the circumferential direction between the upper pressing ring 7 and the lower pressing ring 8 .

Abstract

The invention belongs to the technical field of extra-large tapered roller bearings, and discloses an extra-large tapered roller bearing with a pin-type cage. Pass through the through hole of the upper retaining ring body; the inner wire hole is evenly arranged around the upper part of the lower retaining ring; the lower part of the pin is tightened with the inner wire hole, and the upper part of the pin is sleeved in the pin hole; the countersunk head screw hole is fixed Set on one side of the edge of the upper pressure ring; the wire hole is fixed on one side of the lower pressure ring; the pressing screw is set on one edge between the tapered rollers, and the pressing screw passes through the countersunk head screw of the upper pressing ring. The hole is tightened with the screw hole of the lower pressure ring. The invention improves the assembly precision of the extra-large tapered roller bearing, improves the rotation precision of the extra-large tapered roller bearing; avoids the deformation of the connecting pin or the falling off of the pin due to welding, and realizes the alignment of the pin. solder-free.

Description

technical field [0001] The invention belongs to the technical field of extra-large tapered roller bearings, in particular to an extra-large tapered roller bearing with a pin-type cage. Background technique [0002] Extra-large tapered roller bearings are mainly used in the main shaft of wind power. Extra-large tapered roller bearings are mainly divided into single-row, double-row, three-row and four-row models. Extra-large tapered roller bearings can bear large combined radial and axial loads. Due to their large radial and axial loads, they are widely used in wind power and large equipment fields. [0003] In the prior art, the cage of an extra-large tapered roller bearing is composed of an upper retaining ring and a lower retaining ring. The tapered rollers are evenly arranged around the circumference of the upper retaining ring and the lower retaining ring, and use pins to pass through the upper retaining ring. , The center of the lower retaining ring and the tapered roll...
