Abstract
The utility model provides a speed reducer motor flange which belongs to the technical field of machinery and solves the problems that an existing speed reducer motor flange is poor in sealing effect and an oil seal is short in service life. The speed reducer motor flange comprises a main body provided with a central hole, the central hole is of a step shape, a dust-proof ring and a framework oil seal are sequentially arranged in a large hole of the central hole, the dust-proof ring is positioned on the inner side of the large hole, an outer end face of the framework oil seal is leveled with an end face of the large hole, the large hole of the central hole is arranged on one side of the main body towards a motor casing, and a chamfer is arranged at the opening portion of the large hole. The speed reducer motor flange has the advantages of being convenient to install, good in sealing effect and long in service life of the oil seal.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of flange, particularly a kind of speed reducer motor flange.
Background technique
The speed reducer motor flange is an electric motor end cap, also is the speed reducer end cap, and an end links to each other with speed reducer, and the other end is connected with motor, and worm shaft directly is connected with motor shaft through the flange center hole, is provided with oil sealing sealing between worm shaft and the flange center hole.Usually the flange center hole is a straight hole, and like this when oil sealing is installed, oil sealing is crooked easily to cause the speed reducer leakage of oil.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed the speed reducer motor flange of a kind of easy for installation, good sealing effect, oil sealing long service life.
The purpose of the utility model can realize through following technical proposal: a kind of speed reducer motor flange; Comprise the body that offers center hole; It is characterized in that described center hole is stepped and dust ring and outside framework oil seal are installed in the macropore of center hole successively, described dust ring is positioned at the macropore inboard; Described outside framework oil seal exterior edge face is at a stalemate flat with big hole end surface, and the macropore of described center hole is positioned on the body and offers chamfering towards electric machine casing one side and at big orifice part.
Compared with prior art; The utility model is re-established as the flange center hole stepped, and in the macropore of center hole, outside framework oil seal is set, and is close to step end face when oil sealing is installed in the center hole macropore; The assurance outside framework oil seal is vertical with worm screw; Easy for installation, good sealing effect, the oil sealing long service life is installed dust ring simultaneously and can be prevented that dust from coming in.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, body 2, center hole 21, macropore 3, outside framework oil seal; 4, dust ring.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, this speed reducer motor flange comprises the body 1 that offers center hole 2, and center hole 2 is stepped and dust ring 4 and outside framework oil seal 3 are installed in center hole 2 macropores 21 successively, and wherein dust ring 4 is positioned at macropore 21 inboards.Outside framework oil seal 3 and macropore 21 interference fit and outside framework oil seal 3 exterior edge faces and macropore 21 end faces maintain an equal level mutually; The macropore 21 of center hole 2 is positioned on the body 1 and offers chamfering towards electric machine casing one side and at macropore 21 oral areas; The aperture of center hole 2 and worm shaft just can form oil storage space like this, are beneficial to lubricatedly, reduce the oil sealing wearing and tearing; Improve oil sealing working life, chamfering is convenient to the installation of outside framework oil seal 3.
During installation; Elder generation packs dust ring 4 in the macropore 21; Again outside framework oil seal 3 interference are packed in the macropore 21 and lean on flatly, just put down, then flange body 1 is inserted in worm shaft together with outside framework oil seal 3 with macropore 21 aperture oral area end faces are at a stalemate with end face in the center hole 2; Be connected through the speed reducer casing of screw, be connected with the electric machine casing on its right side through screw at last with its left side.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
