Description
Technical field
The utility model relates to main reducing gear field.
Background technique
Existing motorbus axle main speed reducer assembly, the flange nut that locking mode between its flange with drive bevel gear is generally fluting coordinates the locking of cotter pin, through hole is started at active conical tooth wheel end, on flange nut, corresponding through hole arranges the slotted eye for wearing cotter pin simultaneously, this locking mode is: first screw flange nut, then by the through hole of cotter pin through the slotted eye on flange nut and active conical tooth wheel end, thus the two is fixed together; Make it to relatively rotate by cotter pin constraint screw thread.Although this structure anti-loosening property is good, efficiency of assembling is lower, and operation requirements is very high; In rotational lock flange nut process, usual cotter pin slotted eye position cannot ensure to match with the through hole optimum position of flange nut, simultaneously strict to the requirement of pre-fastening moment, otherwise can cause not tight, thus causes beating tooth, very inconvenient.
Summary of the invention
For the problems referred to above, it is more solid and reliable that the technical problems to be solved in the utility model is to provide a kind of structure, the main gearbox assembly that efficiency of assembling is higher.
For achieving the above object, the utility model is by the following technical solutions:
A kind of Novel main reducing gear assembly, comprise final drive casing, flange, flange lock jack panel, drive bevel gear, by dynamic bevel gear, tapered roller bearing, bearing support, guide bearing and differential assembly; Described flange is connected by spline fitted with drive bevel gear, described flange lock jack panel and drive bevel gear pass through screw-thread fit and press flange, the end of described drive bevel gear is provided with at least one opening slot, and described flange lock jack panel is by pounding flat formula structure and opening slot locks flange.
Further, described guide bearing is also provided with the limit structure for preventing guide bearing from coming off matched with final drive casing.The jump-ring slot structure in former drive bevel gear can be saved after setting up limit structure, realize the limit function to guide bearing band equally, effectively avoid the guide bearing generation play because the problems such as jump-ring slot dimensional accuracy cause.
The beneficial effects of the utility model are: in drive bevel gear end opens opening slot structure, first by pre-fastening moment, flange lock jack panel is screwed in drive bevel gear, then part corresponding with opening slot on flange lock jack panel is fitted in the opening slot of drive bevel gear and (such as uses hammer to knock flange nut and the corresponding position of opening slot by operator, this position is inwardly recessed in opening slot), form and pound flat formula structure; Adopt the locking mode of the flange lock jack panel of this structure of the utility model, solid and reliable, Absorbable organic halogens controls pre-fastening moment, prevents main gearbox assembly from producing the fault such as abnormal sound, gear mill morning; Which overcome the deficiency of traditional locks locking structure, reduce the labor intensity of operator, greatly improve efficiency of assembling, reduce cost of production, improve the competitiveness of product in market.
Accompanying drawing explanation
Be described in further detail with regard to embodiment of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of drive bevel gear;
Fig. 3 is the enlarged diagram in I portion;
Fig. 4 is the enlarged diagram in II portion.
Embodiment
With reference to a kind of Novel main reducing gear assembly shown in Fig. 1, comprise final drive casing 5, flange 2, flange lock jack panel 1, drive bevel gear 6, by dynamic bevel gear 7, tapered roller bearing 10, bearing support 3, guide bearing 8 and differential assembly 9, wherein said flange 2 is connected by spline fitted with drive bevel gear 6, described flange lock jack panel 1 passes through screw-thread fit and press flange 2 with drive bevel gear 6, with reference to Fig. 2 be shown in drive bevel gear 6 end opens have in an opening slot 13(figure and only draw an opening slot, reality can increase opening slot quantity according to processing needs), with reference to shown in Fig. 3, flange lock jack panel 1 screws in drive bevel gear 6 by pre-fastening moment, then operator knock part corresponding with opening slot 13 on flange lock jack panel 1 and make it to inwardly concave in opening slot, form and pound flat formula structure 11, thus locked flange lock jack panel 1.
Described guide bearing 8 is installed on drive bevel gear 6 lower end, is usually provided with jump-ring slot in drive bevel gear lower end and coordinates jump ring to prevent because the axial motion in guide bearing of guiding drive bevel gear causes guide bearing to come off; Eliminate in the present embodiment and original jump-ring slot structure is installed, what substitute mutually arranges limit structure 12(as shown in Figure 4 in the periphery of guide bearing), limit structure 12 coordinates main deceleration shell 5 effectively to stop it to move downward, and effectively avoids because the problems such as jump-ring slot dimensional accuracy cause guide bearing generation play.
The above; be only the better embodiment of the utility model; but the utility model protection domain is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore the utility model protection domain is as the criterion with the protection domain of claims.
Claims (2)
