[0001] The utility model relates to the technical field of motor shaft oil seal equipment, in particular to a friction-resistant and silent seal ring for a motor. Background Art

[0002] With the continuous development of modern industry, the use of motors is increasing. Motors need to use lubricating oil to maintain the rotation performance of the machinery. In order to prevent the overflow of lubricating oil, oil seals are usually used. Oil seals, also known as sealing rings, are usually made of nitrile rubber. Oil seals made of nitrile rubber are not only wear-resistant, but also have a silent effect.

[0003] When installing the oil seal, it is necessary to keep the oil seal level and apply force evenly. Therefore, a press is usually used to press the oil seal for installation. However, during the actual installation process, the size of the contact part between the pressure plate and the oil seal does not meet the requirements, the pressure plate size is smaller than the oil seal size, and other situations will cause the internal skeleton of the oil seal to be damaged, resulting in the deformation of the entire oil seal and it cannot be used. The entire oil seal needs to be replaced, while the nitrile rubber on the outside of the oil seal is intact, resulting in waste of nitrile rubber. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the first embodiment, the utility model provides Figure 1-5 The motor anti-friction and silent seal shown includes:

[0029] Housing mechanism 1;

[0030] Skeleton assembly 2, skeleton assembly 2 is arranged inside the shell mechanism 1, skeleton assembly 2 is used for the external shape support of the shell mechanism 1, skeleton assembly 2 includes a transverse skeleton 201 and a vertical skeleton 202, and the contact part of the transverse skeleton 201 and the vertical skeleton 202 is provided with fixing parts for fixing the transverse skeleton 201 and the vertical skeleton 202.

[0031] The housing mechanism 1 comprises:

[0032] The first housing 101 has a first slot for mounting the vertical frame 202 on its outer wall, and a second slot for mounting the horizontal frame 201 on its outer wall;

[0033] The second shell 102 is sleeved on the outer wall of the first shell 101 .

[0034] The first card slot and the second card slot are arranged perpendicular to each other, the outer wall of the first shell 101 is provided with a connecting piece 7 for fixedly connecting the first shell 101 and the second shell 102, and the outer wall of the first shell 101 is provided with an anti-seepage ring 6 for preventing leakage between the first shell 101 and the second shell 102.

[0035] The connecting member 7 comprises:

[0036] A connecting column 701, one end of which is fixedly connected to the outer wall of the first housing 101;

[0037] The clamping cap 702 has one end fixedly connected to the other end of the connecting post 701 .

[0038] The outer wall of the second shell 102 is provided with a slot for inserting the connecting column 701, and one end of the slot is provided with a limiting groove for limiting the movement of the connecting column 701. The side of the second shell 102 facing the first shell 101 is provided with a groove for inserting the anti-seepage ring 6.

[0039] Fixing parts include:

[0040] The fixing bolt 203 is provided on the outer wall of the horizontal frame 201 with a through groove for inserting the fixing bolt 203 , and the outer wall of the vertical frame 202 is provided with a threaded groove, and the fixing bolt 203 is threadedly inserted and connected with the threaded groove.

[0041] The first shell 101 and the second shell 102 are both annular. The first shell 101 is used to be sleeved on the outer wall of the motor shaft, and the second shell 102 is sleeved on the outer wall of the first shell 101. The shell mechanism 1 is used to seal the motor shaft to prevent leakage of lubricating oil. The horizontal frame 201 and the vertical frame 202 are arranged perpendicular to each other. The position and number of the thread grooves correspond to the number and position of the through grooves. The number of through grooves corresponds to the number of fixing bolts 203. A plurality of fixing bolts 203 are provided, and a plurality of fixing bolts 203 are arranged at equal intervals in a ring. The vertical cross-section of the through groove is T-shaped. The threads on the inner wall of the thread groove are engaged with the threads on the outer wall of the rod of the fixing bolt 203. The rod of the fixing bolt 203 is inserted into the through groove and connected with the thread of the thread in the thread groove, so that the head of the fixing bolt 203 is squeezed against the through groove, driving the horizontal frame 201 to move closer to the vertical frame 202, thereby realizing the fixed installation of the horizontal frame 201 and the vertical frame 202. The through slot and the limiting slot are opened perpendicular to each other. The sizes of the through slot and the limiting slot are respectively the same as those of the vertical frame 202 and the horizontal frame 2 01, the vertical skeleton 202 is annular, and the horizontal skeleton 201 is cylindrical. When installing the first shell 101 and the vertical skeleton 202, because the first shell 101 is made of rubber, the first shell 101 can be pressed to install the vertical skeleton 202 and the first shell 101. At least four anti-seepage rings 6 are provided, and the four anti-seepage rings 6 are divided into two groups. The two groups are symmetrically arranged on both sides of the top of the first shell 101. The anti-seepage rings 6 and the grooves are adapted to each other, and the anti-seepage rings 6 are integrated with the first shell 101. The first shell 101 and the second shell 102 are manufactured in an integrated manner. The anti-seepage ring 6 and the groove are squeezed together to prevent leakage between the first shell 101 and the second shell 102. The connector 7 is provided between the two anti-seepage rings 6. Multiple connectors 7 are provided, and the multiple connectors 7 are evenly spaced in an annular pattern. The connecting column 701, the snap cap 702, and the first shell 101 are manufactured in an integrated manner. The connecting column 701 and the snap cap 702 are made of the same material as the first shell 101. The through-slot is the same size as the connecting column 701, and the diameter of the limiting groove is 1 / 2 of the through-slot size.The clamping cap 702 is a hemispherical shape with the same diameter as the limiting slot. Therefore, when installing the first and second shells 101 and 102, the second shell 102 is pulled to insert the connecting piece 7 into the through-slot and limiting slot, thereby restricting the movement of the second shell 102 and completing the fixed installation of the first and second shells 101 and 102. When removing the second shell 102 from the first shell 101, the clamping cap 702 is first squeezed, and then the second shell 102 is pulled to remove the connecting piece 7 from the through-slot, thereby separating the first and second shells 101 and 102. By removing the fixing bolts 203, the damaged transverse frame 201 or vertical frame 202 can be replaced separately, or the transverse frame 201 and vertical frame 202 can be replaced as a whole by squeezing the first shell 101. In this way, waste of the first and second shells 101 and 102 can be avoided, saving materials.

[0042] In the second embodiment, the utility model provides a dust lip 3, a spring groove 4 and a spring lip 5, which are applied to the sealing ring in the first embodiment. The dust lip 3 is fixedly connected to the side of the first shell 101 away from the outer wall of the second shell 102, and a spring groove 4 is provided on the other side of the first shell 101 away from the outer wall of the second shell 102. The spring lip 5 is fixedly connected to the other side of the first shell 101 away from the outer wall of the second shell 102.

[0043] The shell mechanism 1, dust lip 3, spring groove 4 and spring lip 5 are similar to those of the existing TC type standard skeleton oil seal. The first shell 101, the second shell 102, the dust lip 3 and the spring lip 5 are all made of nitrile rubber, which is wear-resistant and can achieve a silent effect when the motor transmission part rotates. The first shell 101, the dust lip 3 and the spring lip 5 are cast in one piece. The spring groove 4 is used to install the spring, so that the first shell 101 fits tightly against the outer wall of the shaft to achieve a sealing effect.
