Abstract
The invention belongs to gear cases for rail transit vehicles and provides a gear case for a rail transit vehicle. The gear case for the rail transit vehicle is of the structure that an upper case body and a lower case body are arranged. A driven gear bearing seat is located in the positions of the case combining faces of the upper case body and the lower case body. Two locating pins are distributed at the two ends of the gear case in the direction perpendicular to the case combining faces of the gear case and enable the upper case body and the lower case body to be connected and fixed. A half of the driven gear bearing seat is located in the upper case body 1 and the other half of the driven gear bearing seat is located in the lower case body 2. A stabilizing locating pin is arranged on the case combining faces of the gear case. The distance between the installation position of the stabilizing locating pin and a driven gear bearing is smaller than that between each locating pin and the driven gear bearing. The stabilizing locating pin is located between the case combining faces of the upper case body and the lower case body. A half of a locating pin hole is arranged in the upper case body and the other half of the locating pin hole is arranged in the lower case body. The two halves of the locating pin hole are symmetrically distributed at the two sides of a case body. Due to adoption of the locating mode of the locating pins of the gear case, relative motion, caused by uneven temperature rise, manufacturing and machining errors, case body deformation, impact on the gear case and the like, of the two halves of the driven gear bearing seat on the upper case body and the lower case body is limited, the installation accuracy of the driven gear bearing is guaranteed, and the service life of the driven gear bearing is prolonged.
Description
Technical field
The invention belongs to the rail traffic vehicles gear-box, particularly the gear-box position structure.
Background technique
Gear-box is as the vitals of rail traffic vehicles bogie drive system, and the operation conditions of whole vehicle is had to vital impact.Gear-box is to transmit the indispensable part of Motor torque, mainly parts such as gear housing, driving gear, driven gear, Sealing, bearings, consists of.Adopt the gear-box of upper and lower casing split type structure; Two locating studs are along perpendicular to gear-box mould assembling face direction being arranged in to the two ends of gear-box, and upper and lower casing is connected and fixed.As shown in Figure 1, wherein, the driven gear bearing support is set directly on casing the gear-box profile, and passes through the flask joint of upper box 1, lower box 2.Existing gear-box in use, the short phenomenon in working life of driven gear bearing usually occurs, and the serious bearing that even can make breaks down.
Summary of the invention
The present invention passes through to improve the orientation type of locating stud in gear-box, thereby reaches the working environment that improves the driven gear bearing, improves the bearing purpose in working life.
Technological scheme of the present invention is: rail traffic vehicles has upper and lower housing structure with gear-box, the driven gear bearing support is positioned at the mould assembling face position of upper and lower casing, two locating studs edges are distributed in the two ends of gear-box perpendicular to the direction of gear-box mould assembling face, and upper and lower casing is connected and fixed; Half is positioned at upper box 1 the driven gear bearing support, and half is positioned at lower box 2; The stable position pin is set on gear-box mould assembling face, distance between this stable position pin mounting point and driven gear bearing is little than the distance between locating stud and driven gear bearing, and between upper and lower casing mould assembling face, half is arranged on positioning pin hole on upper box, half is arranged on lower box, and distributes in the casing bilateral symmetry.
The present inventor finds by research: the used for rail vehicle gear-box (as shown in Figure 1) of existing employing upper box 1,2 minutes box structures of lower box, driven gear bearing support 7 is divided into two by gear-box mould assembling face, half is positioned on upper box 1, and half is positioned on lower box 2.Gear-box upper box 1, lower box 2 assembly error during due to inevitably manufacture itself, machining error, mould assembling, and the factors such as slight play of 2 of the distortion of the thermal expansion of the upper box 1 that in the vehicle operating process, temperature rise difference causes, lower box 2 upper box 1, lower box 2 when inhomogeneous, stressed, upper box 1 while being subject to impacting, lower box all can cause the relative displacement between the driven gear bearing support 7 on upper box 1 and lower box 2, reduce the installation precision of bearing, thereby affect the working life of bearing.
Generally, as shown in Figure 3, the locating stud 3 of upper box 1,2 installations of lower box, locating stud 4 lay respectively at the two ends of gear-box mould assembling face along the longitudinal direction, this locating stud orientation type due to locating stud 3, locating stud 4 from driven gear bearing support 7 away from, and main purpose is for the processing of gear-box and assembling, can not effectively address the above problem.
The inventor has proposed a simple and effective way and has solved problem, except common two locating studs that arrange along the longitudinal direction, between the upper and lower casing of gear-box, from the driven gear bearing support, the position close to is provided with the stable position pin.Half of stable position pin-and-hole is arranged on upper box 1, and half is arranged on lower box 2, in the casing bilateral symmetry, distributes.
The stable position pin is installed when the gear-box mould assembling, first the stable position pin is put into during installation on the semi-stability positioning pin hole of lower box, then upper box and lower box mould assembling is realized to the installation of stable position pin.
In the present invention, preferred stable position pin-and-hole is near apart from locating stud than the stable position pin-and-hole apart from the driven gear bearing support.
In the present invention also preferred stable position pin be common straight pin, and for slight interference, coordinate between stable position pin and stable position pin-and-hole.
Adopt the gear-box locating stud orientation type in the present invention, can limit the relative movement between the driven gear bearing support on the upper box that causes due to factors such as temperature rise inequality, manufacture, machining error, box deformation, gear-box are impacted and lower box, thereby guarantee the installation precision of driven gear bearing, improve the life-span of driven gear bearing.
