Abstract
The utility model discloses a main speed reducer shell of a dump truck for mining, which comprises a main speed reducer shell body and is characterized in that the outer surface of the shell body is in a spherical structure; a crescent support frame is arranged in the middle of the spherical structure in a smooth transition manner; a support cylinder is smoothly connected outside the spherical structure; and a reinforcing rib is arranged on the inner surface of the shell body. In the utility model, the outer surface of the main speed reducer shell body is arranged into a spherical structure; the support frame is smoothly arranged inside the spherical structure; the support cylinder is smoothly connected outside the spherical structure; and the reinforcing rib is arranged on the inner surface of the shell body, thus satisfying the requirements on the support strength and the rigidity of the shell body, simplifying the casting technique, eliminating the stress concentration in casting, and improving the casting quality and the casting yield.
Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of quarry tipper final drive casing.
Background technique
At present, dumping car comprises two big classes: articulated truck and rigidity dumping car.How the rigidity dump truck is divided into two kinds of hydraulic machine transmission dump truck and electric machinery transmission dump trucks again by the kind of drive.The dump truck of useful load more than 20T, because carrying capacity is big, boundary dimension is wide, surpassed the usage requirement of highway to vehicle, generally can not move in highway, so claim non-highway dumping car, this type of dumping car is mainly used in surface mine and underground mining, sometimes also be used for quarry and water conservancy, construction engineering, claim quarry tipper again.
Quarry tipper is mining transport vehicle, belong to one of mining equipment, be mainly used in the transportation of ore and other bulk cargo in mine, its working environment is more abominable, most of quarry tippers all are fully loaded operations, and frequent climb and fall, applying working condition are comparatively complicated, and all work continuously mostly, transmission part is had relatively high expectations.Rear-end gear reduction is the core of back axle transmission part, and driving and driven bevel gear bears than high pulling torque and impulsive load when the quarry tipper heavy duty, and this is just to the intensity of supporting part final drive casing partial structurtes and having relatively high expectations of rigidity.The structural designs of outer stiffening rib are adopted at the concentrated position of the outer surface stress of the rear-end gear reduction shell of the heavy-load automobile that generally uses more now, though strengthened the intensity and the rigidity of final drive casing to a certain extent, but it is complicated that this structure makes casting mould make, cost is higher, require also higher to casting technique, and the final drive casing outer surface is because step cooperates reinforcing rib structure, and the product that casts out is easy to generate stress and concentrates, and influences the final drive casing casting quality.
Summary of the invention
The utility model purpose provides a kind of quarry tipper final drive casing, by the improvement to structure, has satisfied the requirement of housings support intensity and rigidity, has simplified casting technique, has eliminated the stress of casting and has concentrated, and has improved the quality and the yield rate of foundry goods.
For achieving the above object, the technical solution adopted in the utility model is: a kind of quarry tipper final drive casing, comprise a bevel housing, described housing outer surface is a spheric structure, described spheric structure middle part smooth transition is provided with the crescent shape supporting frame, the smooth supporting drum that is connected with in the described spheric structure outside, described shell inner surface is provided with stiffening rib.
In the technique scheme, final drive casing agent structure outer surface is designed to a spheric structure, with the crescent shape support frame, the transition of cylindrical support tube whole smooth connects, the shell inner surface design has stiffening rib, shell construction is simple, casting technique is good, the casting cost is low, and can be according to the structure and the force-bearing situation of final drive casing inside transmission component, internal surface layout design at housing is dissimilar, the stiffening rib of quantity and size satisfies housings support intensity and rigidity requirement, the position that the outer surface stress of final drive casing is as compared with the past concentrated adopts step to cooperate the structural design of outer stiffening rib more, though strengthened the intensity and the rigidity of final drive casing to a certain extent, but because outer surface has cambered surface to arrive the boss structure transition suddenly, this structure is because non-smooth transition, with respect to the smooth sphere structure, the stress concentration phenomenon appears when stressed easily.Casting mould is made complicated, and the casting cost is higher, and also higher to the casting technique requirement, internal stress appears in foundry goods easily, and the final drive casing casting yield is low.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, since the utility model by spheric structure being set at surface of shell, the inboard smooth connection crescent shape supporting frame of spheric structure, the smooth connection supporting drum in the spheric structure outside, and stiffening rib is set in shell inner surface, thereby satisfied the requirement of housings support intensity and rigidity, and simplified casting technique, eliminated the stress of casting and concentrated, improved casting quality and casting yield;
2, the utility model is simple in structure, and casting is convenient, and cheap for manufacturing cost, is fit to promote the use of.
Description of drawings
Fig. 1 is the utility model embodiment one a front view;
Fig. 2 is the utility model embodiment one a side sectional view;
Fig. 3 is the utility model embodiment one a rear view.
Wherein: 1, housing; 2, spheric structure; 3, crescent shape supporting frame; 4, supporting drum; 5, stiffening rib.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: extremely shown in Figure 3 referring to Fig. 1, a kind of quarry tipper final drive casing, comprise a bevel housing 1, described housing outer surface is a spheric structure 2, described spheric structure middle part smooth transition is provided with crescent shape supporting frame 3, the smooth supporting drum 4 that is connected with in the described spheric structure outside, described shell inner surface is provided with stiffening rib 5.
This structure in use, the design of final drive casing agent structure outer surface is a sphere, be connected with crescent shape support frame, the transition of cylindrical support tube whole smooth, the shell inner surface design has stiffening rib, according to the structure and the force-bearing situation of final drive casing inside transmission component, the stiffening rib of, quantity dissimilar in the internal surface layout design of housing and size satisfies housings support intensity and rigidity requirement.
