Abstract
The utility model belongs to the technical field of railway locomotive component, and particularly relates to a novel gear case for the railway locomotive. The novel gear case improves the rigidity of the whole gear case and settles problems of rubber tape vibration and unsmooth oil returning in the use process of the gear case. The novel gear case for the railway locomotive comprises an upper case body and a lower case body. The novel gear case is characterized in that: combination surfaces of the upper case body and the lower case body are connected through a flange; a position for mounting the rubber strip on a neck ring on the lower case body is provided with a groove; and the cross section of the rubber strip has a convex surface shape which is matched with the groove. The novel gear case for the railway locomotive has the following beneficial effects: convenient mounting as a flange connection mode is adopted for the combination surfaces of the upper case body and the lower case body and the whole case body becomes a case structure; improved rigidity; reduced deformation; easy mounting and no easy vibration as neck ring rubber strip mounting groove and convex shape sealing rubber strip are adopted.
Description
Technical field
The utility model belongs to the technical field of railway locomotive parts, is specifically related to a kind of railway locomotive and uses the new gear case.
Background technique
The Placement of the upper and lower casing of gear-box that existing railway locomotive is used is normally at bolt connection part welding steel contiguous block; Whole gear-box rigidity is little, causes easily that the fitting seat position is prone to rhegma, sealing joint strip play, the face seepage that combines between the higher and lower levels wet goods shortcoming.
Summary of the invention
The goal of the invention of the utility model: improve the rigidity of whole gear-box, solve gear-box adhesive tape play and the not smooth problem of oil return in the utilization process.
The utility model adopts following technological scheme to realize:
A kind of railway locomotive is used the new gear case, comprises upper and lower casing, it is characterized in that upper and lower casing junction plane connects through flange, and the position that the eckband on the lower box is installed adhesive tape has groove, and the cross section of adhesive tape is the convex shape with groove fit.
The utlity model has following beneficial effect: easy for installation: upper and lower case junction plane adopts the flange connecting mode, and whole gear-box becomes housing structure, and rigidity strengthens, and has reduced distortion, is easy to install; Adopt eckband adhesive tape mounting groove, male seal adhesive tape, be easy to install, be difficult for play.
Description of drawings
Fig. 1 is the outline drawing of the utility model
Fig. 2 is the sectional drawing of the utility model
Fig. 3 is the adhesive tape scheme of installation of existing gear-box
Fig. 4 is the adhesive tape scheme of installation of the utility model
Among the figure: 1-flange, 2-eckband, 3-adhesive tape.
Embodiment
Be described further in conjunction with the embodiment of accompanying drawing the utility model.
Railway locomotive is used the new gear case, and its upper and lower casing junction plane adopts flange 1 to connect, and shown in Fig. 1, Fig. 2, is about to upper and lower case junction plane and connects with five pairs of flanges, has enlarged area of contact, improves the rigidity of whole gear-box.Lower box eckband 2 is installed the adhesive tape positions and is had the groove that adhesive tape is installed, and changes sealing joint strip 3 into convex surface by the cross section by original plane, and less interference is arranged during installation, adhesive tape is carried out spacing, has overcome the problem of adhesive tape play; Increase the method for spill port quantity and increasing spill port diameter in addition, reach the unimpeded effect of oil return.
