Abstract
The utility model relates to a shaft worm combined mechanism for an automobile pedal motor, which belongs to the improved design of an output main shaft mechanism of an automobile pedal motor and comprises a main shaft and a worm. The utility model is characterized in that the worm is provided with a hollow hole and is sheathed with the main shaft. The outer cylinder surface of the main shaft is provided with knurling patterns and is tightly matched and connected with the circular surface of the hollow hole in the worm. One end of the hollow hole of the worm is provided with an inwards convex riveted edge step, and is riveted and connected with the outer step side surface of the main shaft.
Description
Affiliated technical field
The utility model belongs to the improvement invention of auto pedal motor output mainshaft mechanism.The pedal motor can be used in positions such as the foot treadle, clutch, throttle of automobile.
Background technique
The pedal motor mainly is used in positions such as foot treadle on the high-grade car, clutch, throttle, is used to regulate position, angles such as pedal, clutch, throttle.The pedal motor is one of present most advanced product, and it is little, in light weight to have a volume, and high electrical performance, high anti-electromagnetism are disturbed characteristics such as disturb, but its output mainshaft mechanism is the same with similar other products, still has some deficits, and needs improvement.Existing output main shaft links to each other with worm screw, because the worm screw diameter is less, and the tooth insufficient strength, fragile; Too small because of tooth again, self-lock force is not enough, influences work.
Summary of the invention
The purpose of this utility model is that worm tooth intensity on the solution auto pedal motor output shaft, self-lock force are not enough, and a kind of firm axle worm screw combined mechanism that connects is provided.
The purpose of this utility model is reached by following technological scheme: it comprises main shaft and worm screw, described worm screw has middle cavity and described main shaft is nested, the outer cylinder surface of described main shaft is provided with the annular knurl decorative pattern and becomes secure fit to connect with the middle empty internal circular surfaces of described worm screw, and the riveted that an end in the middle cavity of described worm screw is provided with convex becomes riveted to connect along rank with the side, evagination rank of described main shaft.
The utility model is finished by following technology: the outer cylinder surface with main shaft becomes the annular knurl decorative pattern through machine tooling earlier, be pressed in the middle cavity of the worm screw that cooperation in advance processes and become secure fit, the riveted of worm screw one end is inwardly pressed along rank to connect again with the evagination rank riveted of main shaft.
Use technical solutions of the utility model that following advantage is arranged: 1,, to strengthen the worm screw diameter, promptly strengthened teeth size, strengthened worm tooth intensity and self-lock force, strengthened the life-span, improved efficient owing to adopt main shaft and worm screw socket composite structure; 2, adopt axis hole annular knurl interference fit and termination clinching method, can effectively stop moving axially, coming off between main shaft and the worm screw, internal and external layer relatively rotates, and can avoid fault, increases the service life.
Description of drawings
Further describe embodiment below in conjunction with accompanying drawing
Fig. 1 is model utility embodiment's a structural representation
Fig. 2 is for using the utility model embodiment's pedal motor schematic representation
Number in the figure is represented: 1, main shaft, 2, riveted is along rank, 3, the thick section of axle, 4, worm screw, 5, the axle thin segment.
Embodiment
The auto pedal motor connects with worm gear through axle worm screw combined mechanism.Its worm screw combined mechanism is: the outer worm screw (4) that is with hollow of main shaft (1).Main shaft (1) is divided into two sections in the middle cavity of worm screw (4): thick section of axle (3) and axle thin segment (5).Thick section of axle (3) and axle thin segment (5) outer cylinder surface all are processed into the annular knurl line.The middle cavity of worm screw (4) is also to having thick section in hole and hole thin segment and mating with the main shaft outer cylinder.The thick section of axle (3) external cylindrical surface becomes secure fit to connect with axle thin segment (5) the external cylindrical surface thick section in hole corresponding with the middle cavity of worm screw (4) with the hole thin segment.In worm screw (4), be provided with the riveted of convex along rank (2) to the termination.This riveted is (2) original convex not along rank, after main shaft (1) and worm screw (4) socket, becomes the riveted connection through technique for riveting with the thick section of a main shaft side, rank.
Claims (2)
1, a kind of axle worm screw combined mechanism of auto pedal motor, comprise main shaft and worm screw, it is characterized in that: described worm screw has middle cavity and described main shaft is nested, the outer cylinder surface of described main shaft is provided with the annular knurl decorative pattern and becomes secure fit to connect with the middle empty internal circular surfaces of described worm screw, and the riveted that an end in the middle cavity of described worm screw is provided with convex becomes riveted to connect along rank and with the side, outer rank of described main shaft.
2, the axle worm screw combined mechanism of auto pedal motor as claimed in claim 1, it is characterized in that: the outer cylinder surface of above-mentioned main shaft is provided with the annular knurl decorative pattern and becomes secure fit to connect with the middle empty internal circular surfaces of above-mentioned worm screw to be divided into two sections, promptly thick section and thin segment.
