Description

Technical Field

[0001] The utility model belongs to the technical field of bearing seats, in particular to a bearing seat which is beneficial to improving the lubrication effect. Background Art

[0002] The bearing seat is an important component for supporting and fixing the bearing. Its lubrication effect directly affects the operating efficiency and service life of the bearing. There is a gear bearing seat with two bearing mounting holes arranged at intervals. Two mutually meshing gear shafts are respectively inserted into the bearing mounting holes, so that the oil can be transported from one end of the gear to the other end when the gear rotates, thereby realizing the function of extracting oil. Due to the high pressure at the oil outlet end, part of the high-pressure oil will also leak to the surface of the gear bearing seat, causing leakage;

[0004] This type of gear sleeve needs to be continuously refueled during use to ensure lubrication between the bearing seat and the bearing to reduce wear. During the oil extraction process, due to the high oil pressure and the continuous impact of the oil, the installation position of the bearing seat is easily deflected, thereby affecting the stability of the entire device. Since the sleeve body is designed in an eight-shaped shape for easy processing, the sleeve body can be embedded in the installation position in all directions, and after installation, it is impossible to determine whether it is installed upside down by looking at the appearance. When the installation direction of the sleeve body is wrong, the device will not only fail to absorb oil, but will also cause a large amount of oil leakage, which will greatly affect the progress of production work.

[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] like Figures 1 to 4 As shown, it is a schematic diagram of the structure of the bearing seat that is conducive to improving the lubrication effect provided by the utility model. The bearing seat that is conducive to improving the lubrication effect includes a bearing seat body 10, a positioning groove group 20 opened on one side of the bearing seat body 10, and a bearing cover 30 arranged on one side of the bearing seat body 10. The bearing seat that is conducive to improving the lubrication effect also includes some other functional modules, such as gear bearings inserted on the bearing seat body 10, etc., which should be well known to those skilled in the art and will not be described in detail one by one here.

[0020] The bearing seat body 10 includes an 8-shaped seat body 11, two bearing mounting holes 12 spaced apart on the seat body 11, a high-pressure oil groove 13 opened on one side of the seat body 11, a low-pressure oil groove 14 located on the same side as the high-pressure oil groove 13, an isolation groove 15 opened on the other side of the seat body 11 away from the high-pressure oil groove 13, and two notches 16 respectively opened between the bearing mounting holes 12 and located at both ends of the seat body 11.

[0021] The high-pressure oil tank 13 is spaced apart from the low-pressure oil tank 14, and oil is injected into the low-pressure oil tank 14 from the outside, and the oil in the low-pressure oil tank 14 is sent into the high-pressure oil tank 13 through gear rotation. The high-pressure oil tank 13 and the low-pressure oil tank 14 can respectively provide oil storage space, thereby ensuring the stability of oil inlet and oil injection, and ensuring continuous oil injection during use.

[0022] A connecting groove 141 is provided between the low-pressure oil groove 14 and the bearing mounting hole 12 to connect the low-pressure oil groove 14 with the bearing mounting hole 12. Since the oil pressure in the high-pressure oil groove 13 is relatively high, part of the oil will flow into the bearing mounting hole 12 along the end surface of the seat body 11, thereby achieving a lubricating effect.

[0023] The isolation groove 15 is arranged around the two bearing mounting holes 12, and is arranged at intervals with the opening of the bearing mounting holes 12, and the direction of the groove is consistent with the opening direction of the bearing mounting hole 12. The two ends of the isolation groove 15 are respectively connected to the side walls of the seat body 11. The interior of the isolation groove 15 is filled with a sealing strip. The sealing strip is a common rubber sealing strip, which has the same shape as the isolation groove 15 and the end face exceeds the seat body 11, thereby playing the effect of isolating the two sides of the sealing grid. The sealing strip is an existing technology widely used in the field of industrial production and should be well known to those skilled in the art, so it is only briefly described in the specification and is not illustrated in the drawings of the specification. The two bearing mounting holes 12 and the low-pressure oil groove 14 are both arranged on the same side of the isolation groove 15.

[0024] The notch 16 includes a first notch and a second notch. The first notch corresponds to the position of the high-pressure oil groove 13, and the second notch corresponds to the position of the low-pressure oil groove 14. The notch 16 is arranged at an 8-shaped depression of the seat body.

[0025] A reflux groove 142 is provided between the second notch 16 and the bearing mounting hole 12 . The reflux groove 142 and the isolation groove 15 are located on the same side so as to return excess oil in the bearing mounting hole 12 into the notch 16 and finally into the low-pressure oil groove 14 .

[0026] The positioning groove group 20 includes a ring positioning groove 21 located at the edge of the same side of the isolation groove 15 and a plurality of straight positioning grooves 22 opened between the ring positioning groove 21 and the isolation groove 15 .

[0027] The ring positioning groove 21 is provided at the edge of the seat body 11. The ring positioning groove 21, the straight positioning groove 22 and the isolation groove 15 are all located on a side of the seat body 11 away from the high-pressure oil groove 13. The ring positioning groove 21 and the bearing mounting hole 12 are respectively provided on both sides of the isolation groove 15.

[0028] The centers of the two mounting holes 12 are connected to form a straight line. The ring positioning groove 21 is asymmetrical with respect to the straight line to ensure that the seat body 11 can be engaged with the cover body only when the seat body 11 is placed in the correct direction, so that whether the installation direction of the seat body 11 is correct can be quickly found during the installation process.

[0029] The two ends of the straight positioning groove 22 are respectively connected to the ring positioning groove 21 and the isolation groove 15. The straight positioning grooves 22 are arranged at intervals and have the same spacing. The length extension direction of each straight positioning groove 22 is respectively the same as the radial direction of the corresponding bearing mounting hole 21, so that the straight positioning groove 22 can completely correspond to the bearing cover 30 only when it is correctly installed, ensuring that the installation direction of the seat body 11 is correct. The groove depth of the straight positioning groove 22 is shallower than the groove depth of the ring positioning groove 21.

[0030] The bearing cover 30 includes a cover body 31 , a first protrusion 32 disposed on the cover body 31 , and a plurality of second protrusions 33 disposed on the cover body 31 .

[0031] The cover 31 abuts against a side of the bearing seat body 10 where the positioning groove group 20 is disposed.

[0032] The first protrusion 32 corresponds to the position of the ring positioning groove 21 and matches the shape, and the second protrusion 33 corresponds to the position of one of the straight positioning grooves and matches the shape. When the bearing cover 30 is installed on the seat body, the first protrusion 32 is engaged with the ring positioning groove 21, and the second protrusion 33 is engaged with the straight positioning groove 22 to ensure stability after installation, and the wrong direction of the seat body or the cover body can be found in time during the installation process.

[0033] Compared with the prior art, the bearing seat provided by the utility model is conducive to improving the lubrication effect. Through the isolation groove 15, the oil leaking from the high-pressure oil groove 13 can only enter the bearing mounting hole 12 from one direction. At the same time, the reflux groove 142 and the connecting groove 141 are arranged between the bearing mounting hole 12 and the notch 16 and the low-pressure oil groove 14, so that the oil entering the bearing mounting hole 12 flows back into the low-pressure oil groove 14 after accumulation, thereby guiding the flow direction of the oil, so that the oil can circulate into the bearing mounting hole 12 and flow out, avoiding the long-term accumulation of the oil in the hole and affecting the lubrication. In order to achieve a sliding effect, the positioning groove group 20 is provided on one side of the seat body 11, and the first convex portion 32 and the second convex portion 33 cooperating with the positioning groove group 20 are provided on the bearing cover 30 to specify the installation direction and avoid incorrect installation direction. Specifically, the positioning groove group 20 includes a ring positioning groove 21 and a plurality of straight positioning grooves 22. The ring positioning groove 21 is clamped with the first convex portion 32, and the straight positioning groove 22 is clamped with the corresponding second convex portion 33, so that the bearing seat body 10 has only one installation method, which increases the speed and accuracy of the bearing seat body 10 during installation.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
