Embodiment 1

[0029] Riding inner locking cage, the cage pocket 9 is set from the inside to the outside as the first cylindrical section 1, the conical section 2 and the second cylindrical section 3; the cross-sectional diameter of the first cylindrical section 1 is smaller than the second cylindrical section 3 The cross-sectional diameter of the conical section 2 expands from the first cylindrical section 1 to the second cylindrical section 3, and the connecting edge of the first cylindrical section 1 and the conical section 2 is the internal locking position 4 of the cage.

[0030] Further, the axis of the first cylindrical section 1, the axis of the conical section 2 and the axis of the second cylindrical section 3 are coaxial.

[0031] Further, the inner lock position of the cage is in contact with the spherical rolling elements (steel balls 8 ) installed in the cage in two arcs.

[0032] Further, a plurality of outer diameter bosses 6 are arranged on the outer diameter surface of the c...

Abstract

The invention belongs to the technical field of bearings, is applied to a bearing of a new energy photovoltaic silicon wafer cutting machine, in particular to a riding edge internal lock type retainer; a first cylindrical section, a conical section and a second cylindrical section are arranged in a pocket of the retainer from inside to outside; the diameter of the cross section of the first cylindrical section is less than that of the cross section of the second cylindrical section; the conical section expands from the first cylindrical section to the second cylindrical section; and the position of an internal lock of the retainer is at the joining edge of the first cylindrical section and the conical section. The bearing mounted with the retainer operates flexibly. The retainer ensures high speed and high precision of the bearing and also can lower the noise of the bearing.

Description

technical field [0001] The invention belongs to the technical field of bearings, is applied to bearings of new energy photovoltaic silicon chip cutting machines, and specifically relates to a riding-edge inner-locking cage. Background technique [0002] At present, when coal power generation pollutes the atmosphere and coal energy is depleted day by day, the country vigorously advocates the development of new energy sources, so the application of photovoltaic power generation in our country is expanding day by day. However, the bearings of new energy photovoltaic silicon wafer cutting machines used to produce silicon wafers have always been mainly imported, and the domestically produced bearings have always been lacking in performance. [0003] It is very necessary to study a bearing cage that can be applied to the bearing of the new energy photovoltaic silicon wafer cutting machine and has the properties of low temperature rise, high speed, high machining accuracy, long lif...
