Model utility content
The utility model overcomes existing gearbox upper shell assembling inconvenience, and efficiency of assembling is low, component and the low deficiency of upper shell connection reliability, provide a kind of gearbox upper shell, it is easy to assembly, and efficiency of assembling is high, component and upper shell connection reliability high.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of gearbox upper shell, upper shell bottom surface is provided with pilot hole, upper shell one end is provided with installation transverse slat, upper shell bottom surface is provided with part mounting hole near another position, opposite end, the installation slotted eye that transverse slat is provided with strip is installed, the two ends of installing transverse slat are equipped with attachment post, reinforcement transverse slat being provided with V-arrangement near neutral position is installed protruding, strengthen projection and be provided with connection fastener hole, slotted eye inwall is installed and is provided with several lugs, lug is provided with part attachment hole, upper shell side wall lower ends face is provided with a circle seal boss, the circle of upper shell outer side wall near lower end is provided with several engaging lugs, engaging lug is equipped with assembling fastener hole.
When gearbox upper shell and lower shell body connection, connect fastening by the assembling fastener hole on engaging lug, seal boss on upper shell adds the sealability that upper shell is connected with lower shell body, also make upper shell and the lower shell body location that is linked and packed convenient simultaneously, not easily rock in assembly process, facilitate assembling.Part mounting hole and the installation slotted eye installed on transverse slat facilitate the connection of component, connect fastener hole to be arranged on and to strengthen protruding upper and part attachment hole and be arranged on structural strength lug adding link position, make component and upper shell connection reliability high.The attachment post installing transverse slat two ends facilitates the connection of component.Gearbox upper shell is easy to assembly, and efficiency of assembling is high, component and upper shell connection reliability high.
As preferably, part mounting hole is the through hole in countersunk structure, and on upper shell bottom surface, part mounting hole edge is provided with a ring shape positioning convex, and positioning convex is provided with the spacing bayonet socket of nick shaped.The part mounting hole of countersunk structure connects location conveniently, and spacing bayonet socket serves component and connects spacing effect, component is connected more reliable.
As preferably, the attachment post cross section at transverse slat two ends is installed all in figure of eight structure, between attachment post and installation transverse slat, is provided with the first lightening grooves.The attachment post that component are connected to the figure of eight there will not be the phenomenon of rotation, connect and reliably facilitate.First lightening grooves not only alleviates gearbox weight, and saves material, reduces cost.
As preferably, be connected with stiffening rib between lug and installation slotted eye inwall, lug is close strengthens projection.Stiffening rib adds the join strength of lug.
As preferably, strengthen the protruding side away from part mounting hole and be provided with the second lightening grooves.Second lightening grooves not only alleviates gearbox weight, and saves material, reduces cost.
As preferably, upper shell is vertically connected with erection column on the outer side wall of part mounting hole, is connected with reinforcement gusset between erection column outer wall and upper shell sidewall, and erection column is provided with connection hole.Strengthen the join strength that gusset adds erection column.
Compared with prior art, the beneficial effects of the utility model are: gearbox upper shell is easy to assembly, and efficiency of assembling is high, component and upper shell connection reliability high.
