The invention discloses a device for improving the connection between a transmission output shaft and a spline half shaft, which comprises a half shaft sleeve and a gearbox housing; the transmission housing is fixedly connected with the half shaft sleeve, and one end of the half shaft sleeve is provided with There is a sealing head, the sealing head extends into the gearbox, an O-ring is arranged between the sealing head and the gearbox casing, the O-ring is in radial contact with the gearbox casing and the sealing head, the A polyurethane sleeve is arranged on the closing head, and the polyurethane sleeve is in axial contact with the gearbox casing and the half shaft sleeve. An oil-free bearing is also provided, the inner ring of the oil-free bearing is fixed to the output half-shaft, the outer ring is fixedly connected to the half-shaft sleeve, and the O-ring is elastic, and when the transmission housing and the half-shaft sleeve are squeezed Under the action, it makes surface contact with the gearbox casing and the half shaft sleeve. It ensures that the spline sleeve can be accurately butted into the differential hole, which improves the production cycle and is very suitable for on-site use.
Description
Technical field[0001]The invention relates to the field of precise butt joints of shafts, in particular to a butt joint improvement device of a gearbox output shaft and a spline half shaft.Background technique[0002]At present, the spline half shaft assembly of the gearbox output shaft is connected to the gearbox differential part. Among them, there are two parts, one is the spline connection part inside the differential, this part is the transmission connection, which is responsible for the transmission and reception of torque and speed. The other part is the fit of the spline half sleeve and the differential hole, which not only ensures the fit in the axial direction, but also ensures that the differential hole does not leak oil. However, the current output shaft spline half shaft assembly can only ensure no oil leakage during the test process, but the docking is not accurate enough, and it is often necessary to repeatedly dock, which affects the overall beat, delays the production...
