In the utility model; Each change-speed gearing is that the single-groove grooved ball bearing of spacer ring is supported on the timing gear wheel shaft of speed governing external splines both sides through two inner rings; Form one annular groove between two spacer rings, the terminal point of oil leab is corresponding with annular groove between two spacer rings in the timing gear wheel shaft.
In the utility model, the gear-box that drives reel in the mangle is meant: uncoiling gear-box in the mangle or tandem rolling gear-box or crimping gear case.
In the utility model, input gear shaft and output shaft one end pass through casing, and are furnished with lid, are being provided with corresponding non-contact type labyrinth seal on the casing that passes through.
The advantage of the utility model is: owing in the timing gear wheel shaft, be provided with oil leab; Its starting point is positioned at timing gear wheel shaft one end; Terminal point lays respectively at speed governing external splines both sides; And the timing gear wheel shaft corresponding with single-groove grooved ball bearing; Especially each change-speed gearing is that the single-groove grooved ball bearing of spacer ring is supported on the timing gear wheel shaft of speed governing external splines both sides through two inner rings, forms one annular groove between two spacer rings, and the terminal point of oil leab is corresponding with annular groove between two spacer rings in the timing gear wheel shaft; Lubricating oil is forced by the oil leab in the timing gear wheel shaft and introduces single-groove grooved ball journal, burns out because of oil starvation when avoiding single-groove grooved ball bearing to work effectively.
