Problems solved by technology

[0004] The shaft gearboxes with shifting mechanisms in the field of large-scale machines generally have unstable shifting, complex lubrication systems (difficult to process and assemble), and general lubrication effects, which cannot meet the bearing lubrication requirements for low-speed operations. For example: Some high-speed axle gearboxes (patent No. 200720039153.2) have the following disadvantages: (1) The mounting plate and two lifting lugs take up a lot of space, which is not compact enough, and the lifting lugs are cast on the top of the box, and the hanging strength is insufficient , the connection is not stable enough; (2) There is no oil return and oil collection structure inside the box, and when the gears cannot effectively stir up the oil when operating at low speed, the lubrication requirements of the bearings cannot be met; (3) The shift lever of the gearbox It is supported on the mounting plate, and there is no support hole at the other end, resulting in poor shift stability; (4) In addition, the gearbox box is the same as the box of the axle gearbox of the domestic ballast distribution truck and tamping truck, and there is no observation Windows and real-time monitoring of the bearing and oil temperature structure, which is not easy to maintain, but also has potential safety hazards

Embodiment 1

[0059] Such as Figure 1 to Figure 8 As shown, a compact self-lubricating axle gearbox box mainly includes: a first box body 1, a second box body 2, a cylinder support 7, a suspension support 4, a first half bearing seat (1-1 , 2-4), the second half bearing housing (1-5, 2-5) and the side beam 3, the first box body 1 is provided with the first oil chamber observation window 1-3, the second oil chamber observation window 1-4 and bearing temperature sensor interface, the second box body 2 is provided with a first main oil chamber 16, a second main oil chamber 17, a second oil chamber 18 and an oil sample sensor interface 9, and the first box body 1. The second box body 2 is fastened and connected to form a box body with a reasonable oil collection tank and oil return structure. The cylinder support 7 is located directly above the second half bearing seat 1-5 of the first box body 1. The said The hanging support 4 is located above the first half bearing seat 1-1 of the first box...

Embodiment 2

[0082] This embodiment provides a gearbox, including an axle, a driving gear, a driven gear, a spline shaft, and the compact self-lubricating axle gearbox case in Embodiment 1. The driven gear is sleeved on the axle and passes through the axle. Ying fit, the axle is installed in the first bearing seat of the compact self-lubricating axle gearbox box through two single function bearings, the spline shaft is installed in the inner hole of the driving gear through the needle bearing, and the driving gear is installed in the compact self-lubricating axle gearbox Lubricate the second bearing housing of the axle gearbox case.

[0083] Other structural components of the gear box can refer to the prior art, and will not be repeated here.

[0084] By using the compact self-lubricating axle gearbox case in Example 1, the gearbox works better.

Embodiment 3

[0086] This embodiment provides a walking transmission system, including a shift mechanism and the gear box in Embodiment 2. The shift mechanism includes a shift fork, a shift fork rod and a cylinder, one end of the shift fork rod is connected to the shift fork, and the shift fork rod The other end of the cylinder is connected to the output end of the cylinder, the shift fork is connected to the spline shaft, and the spline shaft can be connected to the output shaft of the input motor;

[0087] When coupling is required, the cylinder can disengage the spline shaft from the output shaft of the input motor, and the gearbox is idling;

[0088] When self-running is required, the cylinder can connect the spline shaft to the output shaft of the input motor, the input motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate.

[0089] Wherein, the connection and self-running are both conventional states in the field, so they will not be described ...

Abstract

The invention provides a compact type self-lubricating axle gearbox box body, a gearbox and a walking transmission system, and relates to the technical field of mechanical transmission. The compact type self-lubricating axle gearbox box body comprises a first box body, a second box body, an air cylinder support, a hanging support, a second semi-bearing pedestal and a semi-bearing pedestal. The first box body and the second box body are firmly connected to form the box body, a reasonable oil return and oil collecting structure is provided, and a self-lubricating oil path is formed. The first box body is provided with an oil cavity observation window and a bearing temperature sensor interface; the second box body is provided with an oil cavity and an oil sample sensor interface; and the compact type self-lubricating axle gearbox box body has the characteristics of compact structure, good self-lubricating effect and stable and firm connection. In addition, the change condition of the temperature of the bearing and the temperature of oil in the box body can be monitored continuously, and the work safety and reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a compact self-lubricating axle gear box body, a gear box and a running transmission system. Background technique [0002] The axle gearbox is used to transmit the power and speed input by the power source, thereby driving the wheel set to rotate. It is a key component of the vehicle's driving transmission system. The box is also an important part of the axle gearbox. The quality of the box directly determines the axle gear. The service life and working effect of the box. [0003] With the rapid development of overseas markets in the field of railway equipment in my country, the gearboxes used for exporting railway maintenance machinery and vehicles, especially axle gearboxes with shifting mechanisms, must not only meet the requirements of low-speed operation and high-speed gear shifting, but also Need to meet the requirements of smooth shifting, good lubrication,...
