Abstract
The invention discloses a machining method of a bearing supporting frame of a middle shaft of a small car. The machining method comprises the following steps that (1) a section of bearing sectional material to be machined is taken, a bent part is formed at the upper portion of the sectional material, and an included angle of 6.5 degrees is formed between the bent part and a first machining hole in the vertical direction; (2) the included angle of 45 degrees is set between the plane of two lateral plates of the supporting frame and the horizontal plane, the distance between the center of the first machining hole and a top small hole of the bent part is 30 mm, and the included angle between the central line of the hole and a part in the vertical direction is 60 degrees; (3) the first machining hole and an end surface are machined firstly, and then the surface of an upper boss is machined with an inner hole in the bottom end of the bent part and the end surface as the datum reference; (4) the two lateral plates of the supporting frame are machined. The machining method of the bearing supporting frame of the middle shaft of the small car has the advantages that a bearing produced through the method is favorable for stabilization of a roller and fixation of the roller in the installation process, can be modified conveniently according to different types of cars and can be timely replaced or maintained conveniently.
Description
Technical field
The present invention relates to automobile technical field, relate in particular to a kind of support of bearing processing method of kart jackshaft.
Background technology
Progress along with technology, in the front and Frontal offset impact process of car load, when often there is enging cabin and causing driver's shank and step space by compression to the space invasion of driving cabin, steering column mandrel makes its chest trauma evil or directly causes driver dead to driver's chest play, leg room is extruded and increases rescue difficulty, therefore collapse type tubing string is widely applied on car load, and shrinkable sliding steering jackshaft is also applied on car load gradually simultaneously.
At present, turn to transmission jackshaft mostly to be splined sleeve and splined shaft is in mating connection, spline fitted is conducive to turn to the flexible of transmission jackshaft, is convenient to plant personnel assembling and is conducive to turn to the crumple of transmission jackshaft simultaneously when there is car load collision.Client requires also more and more higher to car load comfortableness, particularly the comfortableness of handling maneuver, can affect lubricated reliability because heating up and lacking lubricant but turn in the long-term use procedure of transmission jackshaft; Splined sleeve is the inner vacuum that easily forms in use, affects the slip of jackshaft, reduces the comfortableness of steering operation.
Thereby, for the support of bearing of jackshaft, produce and exist certain drawback, therefore, for above aspect, need to make effective innovation.
Summary of the invention
The object of this invention is to provide a kind of can minimizing accident in driver meet with dangerous degree, be conducive to firm roller, be beneficial to when mounted fixing ball, the support of bearing processing method of the kart jackshaft being convenient to improve according to different automobile types, to solve many deficiencies of prior art.
Object of the present invention is carried out specific implementation by the following technical programs:
A support of bearing processing method for kart jackshaft, is mainly comprised of following steps:
(1) get one section of bearing section bar to be processed, in the process of part, this section bar top is offered an oval-shaped dogleg section and is become the angle of 6.5 ° at vertical direction with first machining hole;
(2) the plane of support biside plate and horizontal plane angle at 45 ° is set, and first machining hole center is 30mm to the distance of aperture place, the top plane of dogleg section, and every centerline hole becomes 60 ° of angles with the angle of vertical direction part;
(3) first first machining hole and end face are machined, then take the endoporus of dogleg section bottom and end face and convex platform surface is processed as positioning datum;
(4) last, take endoporus, end face and upper top aperture is positioning datum, machining support biside plate, and wherein main machined surface roughness is 8.0 μ m, remaining surface roughness is 12 μ m.
Described support biside plate is arcuate structure.
The beneficial effect of the support of bearing processing method of kart jackshaft of the present invention is: the bearing parts of producing by the method can minimizing accident in driver meet with dangerous degree, be conducive to firm roller, be beneficial to when mounted fixedly ball, be convenient to improve according to different automobile types, be convenient to change timely or safeguard.
The specific embodiment
The support of bearing processing method of kart jackshaft described in the embodiment of the present invention, is mainly comprised of following steps:
(1) get one section of bearing section bar to be processed, in the process of part, this section bar top is offered an oval-shaped dogleg section and is become the angle of 6.5 ° at vertical direction with first machining hole;
(2) the plane of support biside plate and horizontal plane angle at 45 ° is set, and first machining hole center is 30mm to the distance of aperture place, the top plane of dogleg section, and every centerline hole becomes 60 ° of angles with the angle of vertical direction part;
(3) first first machining hole and end face are machined, then take the endoporus of dogleg section bottom and end face and convex platform surface is processed as positioning datum;
(4) last, take endoporus, end face and upper top aperture is positioning datum, machining support biside plate, and wherein main machined surface roughness is 8.0 μ m, remaining surface roughness is 12 μ m.
Claims (2)
1. a support of bearing processing method for kart jackshaft, is characterized in that, mainly following steps, consists of:
(1) get one section of bearing section bar to be processed, in the process of part, this section bar top is offered an oval-shaped dogleg section and is become the angle of 6.5 ° at vertical direction with first machining hole;
(2) the plane of support biside plate and horizontal plane angle at 45 ° is set, and first machining hole center is 30mm to the distance of aperture place, the top plane of dogleg section, and every centerline hole becomes 60 ° of angles with the angle of vertical direction part;
(3) first first machining hole and end face are machined, then take the endoporus of dogleg section bottom and end face and convex platform surface is processed as positioning datum;
(4) last, take endoporus, end face and upper top aperture is positioning datum, machining support biside plate, and wherein main machined surface roughness is 8.0 μ m, remaining surface roughness is 12 μ m.
2. the support of bearing processing method of a kind of kart jackshaft as claimed in claim 1, is characterized in that: described support biside plate is arcuate structure.
