Abstract
The utility model belongs to the field of automobile gearbox flange forming blank and particularly discloses an improved type automobile gearbox flange forging blank which comprises a first shaft sleeve, a second shaft sleeve, a third shaft sleeve, a fixing substrate, a first through hole, a spline tooth and a second through hole. The improved type automobile gearbox flange forging blank has the advantages that a sleeve in the gearbox flange blank is formed in an integrated mode, so that subsequent secondary finish machining procedure is eliminated, production efficiency is improved, and assembly is simple; through holes are formed in the spline tooth so as to ensure that lubricating oil forms inner circulation in shaft sleeves in the operation process of an automobile, consequently, oil leakage is avoided, production materials are saved, and service life and safety coefficients are ensured. Moreover, the improved type automobile gearbox flange forging blank is low in production cost and easy to popularize.
Description
Technical field
The utility model belongs to automobile gearbox component technical field of forging, is specifically related to a kind of improved automotive and forges blank with transfer case flange.
Background technique
Known from institute, automobile gearbox is mainly used in the connection of various transmission shafts, is one of component important in automobile assembling work, it specifically plays transmitting torque, adjust the effect of various transmission shafts, and make perfectly cooperation between various component, thereby make automobile at the middle acquisition power that advances; And in the composition of gearbox, transfer case flange plays important effect especially, and it is the tie that connects truck drive shaft and gearbox, and the effect with connection and transferring power is so that the quality of transfer case flange directly can embody the gearbox performance is excellent or bad.
The transfer case flange that adopts prior art to forge, can't flow for real core, inner lubricant oil between the spline tooth of its axle sleeve inside, thereby cause occurring the situation of leakage of oil in running, if find untimelyly, cause on the one hand producing between spline tooth and transmission shaft wearing and tearing, serious direct damage; May have an accident on the other hand life is constituted a threat to safely.Cored structure adds the use that has also increased the production material man-hour in enterprise in fact simultaneously, and then increases the cost of production input of enterprise, and more loaded down with trivial details when the assembly connection transmission shaft.
Therefore, based on the problems referred to above, the utility model provides a kind of improved automotive to forge blank with transfer case flange.
The model utility content
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, provide a kind of improved automotive to forge blank with transfer case flange, guarantee that on the one hand transfer case flange end product quality and working life, reduction manufacture cost drop into, and save installation time on the other hand.
Technological scheme: a kind of improved automotive forges blank with transfer case flange, comprises the first axle sleeve, the second axle sleeve, the 3rd axle sleeve, fixed pedestal, the first through hole, spline tooth and the second through hole; Described the first axle sleeve is arranged in the second axle sleeve, and described the second axle sleeve is arranged in the 3rd axle sleeve, and described the 3rd axle sleeve is arranged on fixed pedestal; Described the first through hole is arranged on fixed pedestal; It is inner that described spline tooth is arranged on the first axle sleeve; Described the second through hole is arranged on spline tooth; Described the first axle sleeve, the second axle sleeve, the 3rd axle sleeve, fixed pedestal, the first through hole, spline tooth and the second through hole are by forging round steel or forging molding of square steel.
Preferred described fixed pedestal is circular, and wherein the first number of openings is 6, evenly is arranged on fixed pedestal and has a pair of through-hole diameter at least less than other through-hole diameter and be symmetrical arranged.
Preferred described the second through hole is arranged in the middle of spline tooth and the second number of openings arranges two at least.
Compared with prior art, the beneficial effects of the utility model are:
This improved automotive has the following advantages with transfer case flange: 1, one-body molded at transfer case flange blank middle sleeve, saved follow-up secondary fine procedure, and improved manufacturing efficiency and assembled simpler; 2, on the one hand arrange on spline tooth through hole guaranteed in car running process lubricant oil axle sleeve is inner form in circulation, stop the problem of leakage of oil, also saved on the other hand production material and assurance working life and safety coefficient; While the utility model cost of production is low, easy popularization.
