Abstract
A kind of full-rotating drill transmission case upper layer gusset, including gusset body are machined with the large through-hole a that a diameter is D on the gusset body, and on the right side of the large through-hole a, there are two diameter identical through-hole b and through-hole c for processing；The curved surface including two planes and an arc-shaped surface is processed into the right side of the gusset body, and two of them plane is mutually perpendicular to L-shaped；It is processed into inclined-plane in the front end face of the gusset body and the upper end of right end curved surface, the inclination angle of the inclined-plane opposing upper is α；Arc surface is processed at the left rear corner of the gusset body, and circle center and the center of large through-hole a are concentric where the arc surface.The structure optimized using geomery is designed using reasonable welding groove, improves structural strength and stability, effectively improve the carrying uniformity of transmission case.Its structure is simple, at low cost using reliable, has wide applicability.
Description
Technical field
The utility model relates to a kind of drill unit driving gear-box upper layer gussets, especially a kind of to be suitable for full-rotating drill driving dress
Dedicated full-rotating drill transmission case upper layer gusset in setting.
Background technique
Transmission case is the installation foundation of full-rotating drill hydraulic motor, speed reducer, driving gearshaft etc., and upper layer gusset is to lead
To the installation foundation of column upper flange, while being also subjected to from the horizontal force of flange and because of transmission case levelness mistake
The transverse direction that difference causes suppresses strength power, and to entire transmission case is ensured, steadily movement plays an important role up and down for it.Existing full-rotating drill
Deficiency existing for the gusset of transmission case upper layer mainly has: first is that unreasonable structure makes carrying uniformity bad, weakening entire biography
The bearing capacity of dynamic case；Second is that welding groove, the structure ruler at position associated with large cylinder, speed reducer mounting base etc. in transmission case
Very little equal design is unreasonable, influences welding efficiency, welding quality and bearing capacity.
Summary of the invention
Technical problem: the purpose of the utility model is to overcome the shortcoming in prior art, provide a kind of structure it is simple,
The strong full-rotating drill transmission case upper layer gusset of bearing capacity.
Technical solution: the full-rotating drill transmission case upper layer gusset of the utility model, including gusset body, in the gusset
The large through-hole a that a diameter is D is machined on body, on the right side of the large through-hole a processing there are two the identical through-hole b of diameter and
Through-hole c；It is processed into the curved surface including two planes and an arc-shaped surface, two of them plane phase in the right side of the gusset body
It is mutually vertical L-shaped；It is processed into inclined-plane in the front end face of the gusset body and the upper end of right end curved surface, the inclined-plane opposing upper
Inclination angle be α；Arc surface is processed at the left rear corner of the gusset body, and circle center where the arc surface is with large through-hole a's
Center is concentric.
Diameter of a circle where the gusset body right end arc-shaped surface is identical as the outer diameter of large cylinder on accessory transmission case.
The inclination angle of inclined plane α is 45 °.
The diameter of the through-hole b is greater than the diameter of through-hole c, less than the diameter of through-hole a.
The diameter D of the gusset body large through-hole a is greater than or equal to the outer diameter+1mm of connecting accessory flange at the large through-hole,
And it is less than or equal to the outer diameter+2mm of connecting accessory flange.
The utility model has the advantages that by adopting the above-described technical solution, the utility model uses the structure of geomery optimization, use
Reasonable welding groove design, improves structural strength and stability, effectively improves the carrying uniformity of transmission case.It solves
Unreasonable structure to carry the bad problem of uniformity, enhances the bearing capacity of entire transmission case；And it solves and is driven
The design such as welding groove, the structure size at the associated position such as large cylinder, speed reducer mounting base is unreasonable in case, influences welding effect
The problem of rate, welding quality and bearing capacity.Its structure is simple, at low cost using reliable, has wide applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A partial cutaway view of Fig. 1
Specific embodiment
One embodiment of the utility model is further described with reference to the accompanying drawing:
As shown in Figure 1, the dedicated full-rotating drill transmission case upper layer gusset of the utility model, including gusset body, described
Gusset body on be machined with a diameter be D large through-hole a, the large through-hole a right side processing there are two diameter it is identical
Through-hole b and through-hole c；The diameter of the through-hole b is greater than the diameter of through-hole c, less than the diameter of through-hole a.The right side of the gusset body
The curved surface including two planes and an arc-shaped surface is processed into end face, and two of them plane is mutually perpendicular to L-shaped；At the angle
The front end face of plate body and the upper end of right end curved surface are processed into inclined-plane, and the inclination angle of the inclined-plane opposing upper is α, as shown in Figure 2；
The inclination angle of inclined plane α is 45 °.Arc surface, and circle center where the arc surface are processed at the left rear corner of the gusset body
It is concentric with the center of large through-hole a.Great circle where the gusset body right end arc-shaped surface on diameter of a circle and accessory transmission case
The outer diameter of cylinder is identical.The diameter D of the gusset body large through-hole a is greater than or equal to the outer diameter of connecting accessory flange at the large through-hole
+ 1mm, and it is less than or equal to the outer diameter+2mm of connecting accessory flange.
