Embodiment 1

[0053]A gear box system with adjustable oil level described in Example 1 is composed of a main gear box, an auxiliary oil tank (21), a first oil hole (6), a second oil hole (22), and connecting accessories. The main gear box described therein includes: a box assembly (125), a first shaft (2), a second shaft (131), a third shaft (4), a first gear (3), and a third gear (5) , the first synchronizer (117), the first bearing (201), the second bearing (202, 203), accessories; the first shaft (2), the second shaft (131), the first synchronizer (117) coaxial Center, the first synchronizer (117) is a meshing tooth sleeve, the first shaft (2) is parallel to the horizontal plane, the first gear (3) is empty on the first shaft (2), and the two can rotate relative to each other; The first gear (3) is meshed with the third gear (5), the side wall of the box assembly (125) has a first oil hole (6), and the bottom of the auxiliary oil tank (21) has a second oil hole ( 22), the first oil pass...

Embodiment 2

[0061] Embodiment 2 carries out following improvement on the basis of embodiment 1:

[0062] An oil pump (23) capable of bidirectional rotation is installed on the pipeline (7). When the oil pump (23) capable of bidirectional rotation rotates forward, the gear oil in the box assembly (125) is delivered to the auxiliary oil tank (21 ); On the contrary, when the bidirectionally rotatable oil pump (23) rotates in reverse, the gear oil in the auxiliary oil tank (21) is delivered to the tank assembly (125).

[0063] Fig. 3 is a front view (simplified schematic diagram) of the gearbox system of Embodiment 3 of the innovative solution, a schematic diagram of two oil pumps that can rotate in one direction to realize the mutual change between high oil level and low oil level.

[0064] In Example 3, A oil pump (24) and B oil pump (25) that can rotate in one direction are installed in parallel on the pipeline (7). When the A oil pump (24) rotates and the B oil pump (25) is stationary, th...

Embodiment 5

[0068] The auxiliary fuel tank (21) of embodiment 5 is a closed shell, and the first shut-off valve (12) and the second shut-off valve (13) are installed on the auxiliary fuel tank (21), and the second shut-off valve (13) is connected to the negative pressure air source (42 ), the second oil hole (22) is higher than the actual height of the first oil hole (6), during the process from high oil level to low oil level, the first stop valve (12) is closed, and the second stop valve ( 13) Turn on the negative pressure air source (42), the gear oil in the tank assembly (125) is driven by negative pressure and delivered to the auxiliary oil tank (21); on the contrary, during the process from low oil level to high oil level, the first One cut-off valve (12) is opened to vent atmospheric pressure, the second cut-off valve (13) is closed, and the corresponding gear oil in the auxiliary oil tank (21) is transported to the tank assembly (125) by gravity.

Abstract

The invention discloses a gearbox system with an adjustable oil level height. In a transmission system, the oil level height of gear oil in a gearbox is vital to the lubrication effect on a gear, a bearing and the like, and whether the gearbox can reliably work for a long time is directly influenced. If the oil level is too high, the gear stirs oil to generate too large heat, the oil temperature is overhigh, the gear oil rapidly deteriorates, and the transmission efficiency of the gearbox is low; otherwise, if the oil level is too low, the gear, the bearing and the like cannot be fully lubricated, and the elements can be rapidly worn and lose efficacy. The invention provides the gearbox system with the adjustable oil level height. With the adoption of the gearbox system, with adjustment of the oil level height, the gearbox is ensured to make the gear, the bearing and the like fully lubricated and also not to generate over large heat caused by oil stirring and overhigh oil temperature in different working modes or working environments, and efficient transmission work of the gearbox is ensured.

Description

technical field [0001] The invention relates to a transmission device, in particular to a gear transmission box system. Background technique [0002] In the transmission system, the oil level setting of the gear oil in the gearbox is very important to the lubrication effect of the gears and bearings, which directly affects whether the gearbox can work reliably for a long time. If the oil level is too high, the gear oil will heat up too much, the oil temperature will be too high, the gear oil will deteriorate rapidly, and the transmission efficiency of the gearbox will be low; on the contrary, if the oil level is too low, the gears, bearings, etc. These components quickly wear out and fail. [0003] Optimum oil level setting is a result of multiple influencing factors such as lubrication, heat generation, energy loss, and oil temperature. However, some special gearboxes have more than one working mode or need to work in different working environments. The contradictions cau...
