Problems solved by technology
[0002] In the lubrication and cooling system of the gear transmission system, active lubrication and passive lubrication technology are widely used. Active lubrication mainly has an additional oil pump oil circuit system, and each bearing needs a lubricating oil circuit to increase the cost. The oil tank has the problem of less oil collection, or the installation of oil collecting plate parts is complicated and difficult to process, and most of the oil collecting grooves are used to lubricate a single bearing alone, and are greatly affected by the installation angle of the gearbox, and do not have the function of oil volume adjustment
[0003] For example, the Chinese patent document with the publication number CN107763192 A discloses a "central reducer bearing lubrication structure". The first oil collecting area and the second oil collecting area correspond to the lubrication of the input bearing and the intermediate bearing respectively. Lubrication is not related to each other, the excess oil is directly discharged from the bearing oil chamber, and the effect of the oil sump is greatly affected by the installation of the reducer

Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with accompanying drawing: Figure 1-6 As shown, it is mainly composed of a box body 12, an end cover 13, and a group of bolts 14. The box body is provided with a bearing mounting hole, and the end cover is installed at the installation position of the box bearing hole, and is connected by the bolt group 14. There are two oil sumps at each position of the bearing hole on the box body, the upper oil sump 1, the lower oil sump 2, the upper oil sump 3, the lower oil sump 4, the upper oil sump 5, the lower oil sump 6, and the 7. Oil hole 8, oil hole 9, oil hole 10, oil hole 11, oil hole 12 are connected with the end face of the box body; there are two connected oil passages 16 and 17 on the end cover, and form Empty oil chamber 18. like figure 2 As shown, the oil hole 7 and the oil hole 8 of the casing are connected with the oil passage 16 and the oil passage 17 of the end cover to form a lubricating ...

A gearbox body bearing lubrication structure mainly comprises a box body, an end cover and a bolt group, wherein a bearing mounting hole is formed in the box body, the end cover is installed on mounting positions of bearing holes in the box body, and connected with the bearing holes through the bolt group, an upper oil collection groove and a lower oil collection groove are formed in a position, where each bearing hole is located, on the box body, and communicate with the end face of the box body through oil holes, each upper oil collection groove and each lower oil collection groove which are adjacent and respectively formed in positions of each two adjacent bearing holes are located in the same side, and two oil channels which communicate with each other are formed in the end cover. The gearbox body bearing lubrication structure meets multi-angle installation and installation at a rotation angle of 180 degrees for a gearbox, and guarantees bearing lubrication due to the fact that functions of the upper oil collection grooves and the lower oil collection grooves can be switched.
Description
technical field [0001] The invention relates to a bearing lubricating structure of a gearbox case, belonging to the technical field of gearboxes. Background technique [0002] In the lubrication and cooling system of the gear transmission system, active lubrication and passive lubrication technology are widely used. Active lubrication mainly has an additional oil pump oil circuit system, and each bearing needs a lubricating oil circuit to increase the cost. The oil tank has the problem of small amount of oil collected, or the installation of oil collecting plate parts is complicated and difficult to process, and the oil collecting groove is mostly used for the lubrication of a single bearing, and is greatly affected by the installation angle of the gearbox, so it does not have the function of oil volume adjustment. [0003] For example, the Chinese patent document with the publication number CN107763192 A discloses a "central reducer bearing lubrication structure". The first...
