Abstract
The utility model relates to a kind of motor automobile motor rear end cap; That object is to provide a kind of compact conformation, that intensity is high motor automobile motor rear end cap.A kind of back end cover for motor, comprise end cap body, the axis hole that power supply arbor passes is provided with in the middle of the end face of end cap body, described axis hole protrudes from end cap body end face outside end cap body, the inwall of axis hole is provided with wear-resisting ring, end cap body around described axis hole backward end cap inner recess forms depressed part, and the end cap body interior of described sunk part arranges reinforcement.A kind of motor automobile motor of the utility model rear end cover structure is compact, and makes the intensity enhancing of whole back end cover for motor by arranging reinforcement, and depressed part not easily deformation occurs.
Description
Technical field
The utility model relates to a kind of back end cover for motor, is specifically related to a kind of motor automobile motor rear end cap.
Background technology
In prior art, the rear end cap of motorcycle motor can arrange the axis hole that motor shaft passes, axis hole normally end cap sealing surface middle part outwardly and formed, because perforate makes the intensity of rear end cap reduce, and outstanding axis hole wall also makes the installation volume of whole motor increase, and is unfavorable for the miniaturization of motorcycle.
Utility model content
That main purpose of the present utility model is to provide a kind of compact conformation, that intensity is high motor automobile motor rear end cap.
For achieving the above object, the technical solution adopted in the utility model is: a kind of back end cover for motor, comprise end cap body, the axis hole that power supply arbor passes is provided with in the middle of the end face of end cap body, described axis hole protrudes from end cap body end face outside end cap body, the inwall of axis hole is provided with wear-resisting ring, and the end cap body around described axis hole backward end cap inner recess forms depressed part, and the end cap body interior of described sunk part arranges reinforcement.
That is, the part of end cap body around axis hole is recessed toward cover internal, and the bottom surface of depression leans on the side of end cap body interior to arrange reinforcement.The axis hole given prominence to so just can be made in the past can to retract one section by cover internal, whole motor section partial volume can be effectively reduced.
Further, described reinforcement is multiple, and each reinforcement is evenly arranged along the hole cross circular section of axis hole.That is reinforcement arranges along the even circumferential of the cross circular section of axis hole, like this can support recesses portion better, improves the intensity of end cap body.
Further, the bottom surface of described depressed part is the disk concentric with axis hole cross section.The bottom surface of the depressed part that is around axis hole is circular discoid, and the center of circle of this disk overlaps with the center of circle of axis hole cross section.Stress distribution suffered by such depressed part is more even.
Further, described reinforcement is metallic plate, and metallic plate is perpendicular to the bottom surface of depressed part, and sidewall and the depressed part of the both sides distribution that metallic plate is adjacent and rear end cap are affixed.Namely reinforcement is plate-shape metal material, and plate face is parallel with axis hole central shaft, and the both sides of metallic plate are connected with the bottom surface of depressed part respectively at the inwall of rear end cap.Its firm better effects if on the consumption of identical reinforcement material like this.
Preferred further, described face, reinforcement metallic plate place does not overlap with the diameter of axis hole with the intersecting lens of axis hole cross section, and described reinforcement number is 4.That is the plate face at metallic plate place is different from the central shaft of axis hole on one face, but has certain angle, and metallic plate arranges along the even circumferential of the cross circular section of axis hole, and 4 metallic plates rotate arrangement around axis hole central shaft.When making motor shaft rotate like this, air-flow can form cyclone along metal plate flowing and flow out end cap from axis hole, strengthens heat radiation.
A kind of motor automobile motor of the utility model rear end cover structure is compact, and makes the intensity enhancing of whole back end cover for motor by arranging reinforcement, and depressed part not easily deformation occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of motor automobile motor of the utility model rear end cap.
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Be described as follows with reference to Fig. 1,2: the part of end cap body 5 around axis hole 3 is recessed toward cover internal, the bottom surface of depressed part 2 leans on the side of end cap body 5 inside to arrange reinforcement 1.Described reinforcement 1 is 4, and for being welded on the metallic plate of end cap inner surface, each reinforcement 1 is evenly arranged along the hole cross circular section of axis hole 3.The bottom surface of depressed part 2 is the disk concentric with axis hole 3 cross section.Metallic plate is perpendicular to the bottom surface of depressed part 2, and sidewall and the depressed part 2 of the both sides distribution that metallic plate is adjacent and rear end cap are affixed.The plate face at metallic plate place is different from the central shaft of axis hole 3 on one face, and the angle in the plate face at axis hole 3 central shaft and metallic plate place is 5-20 °, and 4 metallic plates rotate arrangement around axis hole 3 central shaft.The wear-resisting ring 4 of copper material is provided with in axis hole 3.
Claims (3)
1. a back end cover for motor, comprise end cap body, the axis hole that power supply arbor passes is provided with in the middle of the end face of end cap body, described axis hole protrudes from end cap body end face outside end cap body, the inwall of axis hole is provided with wear-resisting ring, it is characterized in that: the end cap body around described axis hole backward end cap inner recess forms depressed part, and the end cap body interior of described sunk part arranges reinforcement; Described reinforcement is metallic plate, and metallic plate is perpendicular to the bottom surface of depressed part, and sidewall and the depressed part of the both sides distribution that metallic plate is adjacent and rear end cap are affixed; Described face, reinforcement metallic plate place does not overlap with the diameter of axis hole with the intersecting lens of axis hole cross section, and the angle in the plate face at axis hole central shaft and metallic plate place is 5-20 °, and described reinforcement number is 4.
2. back end cover for motor according to claim 1, is characterized in that: described reinforcement is multiple, and each reinforcement is evenly arranged along the hole cross circular section of axis hole.
3. back end cover for motor according to claim 1 and 2, is characterized in that: the bottom surface of described depressed part is the disk concentric with axis hole cross section.
