Abstract
The utility model discloses a reduction gear combination formula output shaft, output shaft body front end portion are equipped with the location shaft shoulder that acts on single deep groove ball bearing, and output shaft body front end is equipped with the hubbed flange, its flange neck and output shaft body front end splined connection, the one end that the flange neck corresponds the ring flange is equipped with the concave station, the concave station is equipped with the flange gland, and the flange gland is equipped with the screw that makes it tightly decide in output shaft body front end, is equipped with O type rubber seal between flange gland and the flange neck, the flange neck corresponds the one end of location shaft shoulder and supports the pressfitting with single deep groove ball bearing inner circle. The utility model has the advantages of novel structure, showing reduction in production cost and cost of maintenance.
Description
Technical Field
The utility model belongs to automobile reducer especially relates to a reduction gear combination formula output shaft.
Background
The existing output shaft of the speed reducer is formed by integrally forging and molding an output shaft body and a flange plate at the end part of the output shaft body, and a bearing gland, a framework type oil seal, a single-row deep groove ball bearing and a bearing retainer ring are sequentially arranged on the output shaft from one end of the flange plate to form an output shaft assembly.
The production practice shows that the reducer output shaft assembly has the following defects:
a, the cost of integral forging of the output shaft and the flange plate is high; b, the single-row deep groove ball bearing is only pressed by a bearing retainer ring, the interference magnitude is difficult to control, and the risk of the output shaft falling off exists; c, difficult maintenance and high cost, and any part in the output shaft assembly is damaged, so that the whole assembly can only be replaced.
Disclosure of Invention
The utility model relates to a solve the above-mentioned technical problem that aforementioned reduction gear output shaft exists and provide a reduction gear combination formula output shaft.
The utility model discloses a realize above-mentioned purpose and take following technical scheme: the utility model provides a reduction gear combination formula output shaft, includes the output shaft body, and the characteristic is that, the tip is equipped with the location shaft shoulder that acts on single deep groove ball bearing before the output shaft body, and output shaft body front end is equipped with the hubbed flange, and its flange neck and output shaft body front end splined connection, the one end that the flange neck corresponds the ring flange is equipped with the concave station, the concave station is equipped with the flange gland, and the flange gland is equipped with and makes it tightly fix to the screw of output shaft body front end, is equipped with O type rubber seal between flange gland and the flange neck, the one end that the flange neck corresponds location shaft shoulder supports the pressfitting with single deep groove ball bearing inner circle.
The utility model has the advantages of: the arrangement of the splined connection neck flange at the front end of the output shaft body and the positioning shaft shoulder at the front end part of the output shaft body enables the output shaft of the combined speed reducer to have the following characteristics that the output shaft body and the flange can be forged respectively, and the cost is obviously reduced; the inner ring of the single-row deep groove ball bearing is reliably abutted and jointed by the combined action of a positioning shaft shoulder, a flange neck and a flange gland, the interference magnitude is convenient to control, and the risk of falling off of an output shaft can be effectively avoided; the structure of the combined reducer output shaft is convenient to assemble and maintain, and the maintenance cost is low. The utility model has the advantages of novel structure, showing reduction in production cost and cost of maintenance.

Fig. 2 is an exploded view of the embodiment of fig. 1.
FIG. 3 is a schematic view of an output shaft assembly constructed using the embodiment of FIG. 1.
The labels in the figure are: the device comprises an output shaft body 1, a positioning shaft shoulder 1-1, screw holes 1-2, a neck flange 2, a concave platform 2-1, a 3O-shaped rubber sealing ring, a flange gland 4, a screw 5, a single-row deep groove ball bearing 6, a bearing gland 7 and a skeleton type oil seal 8.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in the embodiment shown in fig. 1, 2 and 3, the front end of the output shaft body 1 is provided with a positioning shaft shoulder 1-1 acting on the single-row deep groove ball bearing 6, the front end of the output shaft body is provided with a flange 2 with a neck, and the flange neck is in splined connection with the front end of the output shaft body.
One end of the flange neck of the flange 2 with the neck, which corresponds to the flange plate, is provided with a concave platform 2-1, the concave platform is provided with a flange gland 4, the flange gland 4 is provided with a screw 5 which is tightly fixed at the front end of the output shaft body 1, and the screw is in threaded connection with a screw hole 1-2 at the front end of the output shaft body 1.
An O-shaped rubber sealing ring 3 is arranged between the flange gland 4 and the flange neck, and one end of the flange neck corresponding to the positioning shaft shoulder 1-1 is in abutting joint with the inner ring of the single-row deep groove ball bearing 6.
As shown in figure 3, when the combined output shaft is used, before the neck flange 2 is not installed, the single-row deep groove ball bearing 6 is installed and is jointed with the positioning shaft shoulder 1-1, then the framework type oil seal 8 and the bearing gland 7 are sleeved in sequence, and then the neck flange 2 and the O-shaped rubber sealing ring 3 thereof are installed to form the output shaft assembly.
A bearing gland 7 in the assembly is fixed on a sheath of the output shaft assembly through screws, the sheath is fixed on a shell of the speed reducer, and a protruding part of the bearing gland 7 is in abutting joint with an outer ring of the single-row deep groove ball bearing 6.
