Description
Technical field
The utility model belongs to supporting construction technical field, is specifically related to a kind of small size electric steering engine output shaft supporting construction, effectively can supports undersized electric steering engine output shaft.
Background technology
The output shaft assembly of electric steering engine is the significant components of steering wheel, is the outlet terminal of steering wheel transmission mechanism, and the supporting construction performance of its output shaft directly affects the performance such as output accuracy and bending resistance square of electric steering engine.Traditional supporting construction is generally: (1), when bending resistance square performance requirement is not high, can arrange a deep groove ball bearing respectively at the two ends of output shaft, its advantage is that physical dimension is little, and shortcoming is that radial load is less; (2) when bending resistance square performance requirement is higher, can arrange a taper roll bearing respectively at the two ends of output shaft, its advantage is that radial load is large, but physical dimension is also larger.
The requirements such as high-power, heavy load, the small size that can not improve electric steering engine along with Missile Weapon System and lighting, require also strict all the more to the supporting construction of output shaft.Not only require that supporting construction size is little, more require to possess very high load-carrying properties.
Therefore, need to propose a kind of output shaft supporting construction, be used for effectively supporting undersized electric steering engine output shaft.
Summary of the invention
The purpose of this utility model be with needle bearing version for break-through point, a kind of small size electric steering engine output shaft supporting construction is proposed.According to practical structures and the requirement of electric steering engine, design corresponding bearing structure parameter, arrange a full pin needle bearing and a full ball deep groove ball bearing at output shaft two ends respectively, thus meet the requirement of supporting construction small size and heavy load.
In order to realize this purpose, the technical solution of the utility model is:
A kind of small size electric steering engine output shaft supporting construction, comprises output shaft, needle bearing cover plate, needle bearing, housing, deep groove ball bearing and deep groove ball bearing cover plate; Needle bearing is arranged on the upper end of output shaft, for bearing radial load, is fixed by needle bearing cover plate; Deep groove ball bearing is arranged on the lower end of output shaft, for bearing axial load, is fixed by deep groove ball bearing cover plate.
Further, a kind of small size electric steering engine output shaft supporting construction as above, wherein: high-temperature alloy steel M50 all selected by the material of needle bearing and deep groove ball bearing.
Further, a kind of small size electric steering engine output shaft supporting construction as above, wherein: the internal diameter of needle bearing is 40mm, and external diameter is φ 55mm, is highly 15mm; The internal diameter of deep groove ball bearing is 40mm, and external diameter is 55mm, is highly 8mm.
The beneficial effects of the utility model are that supporting construction mode is simple, easy to operate, remarkable to the support effect of output shaft.Specifically, a kind of small size electric steering engine of the utility model output shaft supporting construction with needle bearing version for break-through point, according to practical structures and the requirement of electric steering engine, design corresponding bearing structure parameter, arrange a full pin needle bearing and a full ball deep groove ball bearing at output shaft two ends respectively, thus meet the requirement of supporting construction small size and heavy load.The feature of this structure is: the needle bearing of (1) supporting construction is mainly used in bearing radial load, and deep groove ball bearing is mainly used in bearing axial load, meets the load bearing requirements to output shaft on bullet; Appearance and size, the structural parameters such as material and rolling element layout of (2) two bearings all can design according to the practical structures of steering wheel and requirement, can meet the requirement such as small size and heavy load; (3) needle bearing can cancel inner ring according to steering wheel practical structures, using output shaft directly as the inner ring of bearing, thus reduces physical dimension further.
Accompanying drawing explanation
Fig. 1 is a kind of small size electric steering engine output shaft supporting construction schematic diagram.
In figure: 1 output shaft, 2 needle bearing cover plates, 3 needle bearings, 4 housings, 5 deep groove ball bearings, 6 deep groove ball bearing cover plates.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of small size electric steering engine of the utility model output shaft supporting construction, comprises output shaft, needle bearing cover plate, needle bearing, housing, deep groove ball bearing and deep groove ball bearing cover plate; The internal diameter of needle bearing is 40mm, and external diameter is φ 55mm, is highly 15mm; The internal diameter of deep groove ball bearing is 40mm, and external diameter is 55mm, is highly 8mm.Needle bearing is arranged on the upper end of output shaft, for bearing radial load, is fixed by needle bearing cover plate; Deep groove ball bearing is arranged on the lower end of output shaft, for bearing axial load, is fixed by deep groove ball bearing cover plate.In the present embodiment, high-temperature alloy steel M50 all selected by the material of needle bearing and deep groove ball bearing, to meet the actual working environment requirement of electric steering engine.
This output shaft supporting construction is used by the pairing of needle bearing and deep groove ball bearing, under the prerequisite ensureing electric steering engine output accuracy, greatly improves the anti-radial load ability of electric steering engine.Before this output shaft supporting construction of use, under the operating mode of bearing 1500Nm moment of flexure, there is bearing pressure feedback phenomenon in the electric steering engine of the present embodiment.Can bear 2400Nm moment of flexure after using this supporting construction, needle bearing and deep groove ball bearing stand intact, and prove that a kind of small size electric steering engine output shaft supporting construction is effective, Be very effective.
