Abstract
Description
Technical Field
[0001] This application relates to the field of sealing ring fixing technology, and in particular to a steel-framed rubber sealing ring fixing device. Background Technology
[0002] The assembly quality of the seals in a sealed bearing has a significant impact on the product quality. The assembly requires that the seal ring and the outer ring of the bearing be tightly fitted together, with no relative displacement between them, and the steel skeleton inside the seal ring must not undergo plastic deformation.
[0003] According to announcement number CN222437282U, a steel-framed rubber sealing ring fixing device is disclosed. This technology discloses a fixing device comprising an outer sleeve, an outer fixing component, and an inner fixing component. The outer sleeve is fitted over the outer fixing component and is fixedly connected to it. The outer fixing component is fitted over the inner fixing component and is fixedly connected to it. Gaps are left between the two ends of the outer fixing component and the two ends of the inner fixing component. One outer sleeve is located at each end of the outer fixing component. The outer sleeve consists of an upper sleeve and a lower sleeve. This technical solution offers advantages such as good sealing effect and convenient sealing.
[0004] Regarding the aforementioned technologies, the inventors believe the following problems still exist:
[0005] First, the aforementioned sealing ring fixing device uses an outer kit and an outer fastener to connect with the outer surface of the steel frame. However, the aforementioned method of fixing by interference fit still carries the risk of axial slippage, reducing its practicality.
[0006] Secondly, the aforementioned sealing ring fixing device is inconvenient when fixing steel frames with a short axial length. Furthermore, when connecting two steel frames, the two sealing rings may undergo excessive deformation due to their nested arrangement, which could cause the elasticity of the sealing rings to gradually decrease.
[0007] To address the aforementioned problems, the inventors have proposed a steel-framed rubber sealing ring fixing device to solve these issues. Utility Model Content
[0008] In order to improve the above-mentioned device, which has the risk of axial slippage and the problem of excessive deformation of the sealing ring leading to a gradual decrease in elasticity, the purpose of this utility model is to provide a steel skeleton rubber sealing ring fixing device.
[0009] To solve the above problems, this utility model provides the following solution: a steel-framed rubber sealing ring fixing device, comprising two sets of housings, each set of housings consisting of two housings distributed vertically, the outer surfaces of the two sets of housings being jointly fixedly mounted with multiple adjustment mechanisms, a connecting ring being fixedly mounted on one side of one of the housings, a hinge plate being provided on one side of the two housings located in the same set, and the two housings being rotatably connected together through the hinge plate, a connecting ear being fixedly mounted on the side of each housing away from the hinge plate, a fixing bolt being inserted into the internal thread of the connecting ear, the bottom end of the fixing bolt extending to the lower part of the connecting ear and being threaded with a fixing nut.
[0010] Preferably, the adjustment mechanism includes a sleeve plate and a fixing rod, the sleeve plate and the fixing rod are slidably sleeved together, the sleeve plate and the fixing rod are respectively installed on the outer surfaces of two sets of housings, the outer surface of the fixing rod is provided with a plurality of fixing grooves, and the top surface of the sleeve plate is fitted with a locking rod that cooperates with the fixing grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model uses a housing to fix the device to the outer surface of a steel frame by using multiple sets of housings. The multiple protrusions inside the housing engage with the outer surface of the steel frame, thereby preventing the risk of axial movement of the device after prolonged use and improving stability.
[0013] 2. By setting an adjustment mechanism, this utility model can be used with a shorter steel frame when shortened, and can increase the stability of the device and the housing when extended. Through the involute fixed ring in the connecting ring, the two fixing devices can gradually squeeze the rubber sealing ring during installation to prevent the sealing ring from being excessively deformed, thereby reducing the sealing effect of the sealing ring.

[0021] Example: Figure 1-4 As shown, this utility model provides a steel frame rubber sealing ring fixing device, including two sets of shells 1. Each set of shells 1 consists of two shells 1 distributed vertically. Each shell 1 is semi-circular. The two shells 1 in the same set can form a circle. The two sets of shells 1 can fix the device to the steel frame together. Multiple adjustment mechanisms 2 are fixedly installed on the outer surface of the two sets of shells 1. The adjustment mechanisms 2 can adjust the distance between the two sets of shells 1.
[0022] Multiple adjustment mechanisms 2 are arranged in a ring array on the outer surface of the two sets of housings 1. The adjustment mechanisms 2 can fix the two sets of housings 1. The multiple adjustment mechanisms 2 can make the two sets of housings 1 more stable. A connecting ring 3 is fixedly installed on one side of one of the housings 1. The fixing device can be connected by using bolts to cooperate with the connecting ring 3.
[0023] A hinge plate 11 is provided on one side of the two shells 1 in the same group. The hinge plate 11 allows the two shells 1 in the same group to rotate, and the two shells 1 are connected together by rotating through the hinge plate 11, so that the two shells 1 can be opened, making it easier to fit them onto the outer surface of the steel frame.
[0024] Both housings 1 have connecting lugs 13 fixedly installed on the side away from the hinge plate 11. A fixing bolt 14 is inserted into the internal thread of the connecting lug 13. The bottom end of the fixing bolt 14 extends to the lower part of the connecting lug 13 and is threaded with a fixing nut 16. The two housings 1 in the same group can be fixed by the engagement of the fixing bolt 14 and the connecting lug 13.
[0025] A washer 15 is movably fitted on the outer surface of the fixing bolt 14. The washer 15 is located between the fixing bolt 14 and the connecting lug 13. The washer 15 is existing technology and can make the fixing bolt 14 more stable.
[0026] The inner walls of both housings 1 are fixedly equipped with multiple protrusions 12 that cooperate with the steel frame. The protrusions 12 can prevent the housings 1 from sliding radially on the outer surface of the steel frame.
[0027] The adjustment mechanism 2 includes a sleeve plate 21 and a fixing rod 24. The sleeve plate 21 and the fixing rod 24 are slidably connected. The sleeve plate 21 and the fixing rod 24 are respectively installed on the outer surface of the two sets of housings 1, so that the fixing rod 24 slides inside the sleeve plate 21, thereby adjusting the distance between the two sets of housings 1.
[0028] The outer surface of the fixing rod 24 is provided with multiple fixing grooves 25. The fixing grooves 25 are used in conjunction with the locking rod 22. The multiple fixing grooves 25 are distributed at equal intervals to increase the adjustable space. The top surface of the sleeve plate 21 is fitted with a locking rod 22 that is used in conjunction with the fixing grooves 25. The locking rod 22 and the fixing grooves 25 are used in conjunction to fix the fixing rod 24 and the sleeve plate 21.
[0029] The top surface of the sleeve plate 21 is provided with a slot 23 that works with the locking rod 22, so that the fixing rod 24 works with the sleeve plate 21 to move the two sets of sleeve shells 1, and is fixed by the locking rod 22 working with the fixing slot 25, thereby adjusting the distance between the two sets of sleeve shells 1.
[0030] The connecting ring 3 includes two mirror-distributed axial pressure rings 31, which can be connected. The two axial pressure rings 31 are respectively fixedly installed on one side of the two housings 1 in the same group, so that the axial pressure rings 31 rotate together with the two housings 1.
[0031] Two axial pressure rings 31 are fixedly installed with involute retaining rings 32 on the side away from the housing 1. The cross-sectional shape of the retaining ring 32 is a right trapezoid. The involute retaining ring 32 can gradually squeeze the rubber sealing ring to prevent the sealing ring from being excessively deformed.
[0032] Multiple connecting holes 33 are provided on the outer surface of the two axial pressure rings 31. The multiple connecting holes 33 are arranged in a ring array on the outer surface of the axial pressure rings 31. The multiple connecting holes 33 can be used to fix the two fixing devices, thereby driving the two steel frames to be fixed.
[0033] Working principle: First, adjust the adjustment mechanism 2 according to the length of the steel frame. Pull out the locking rod 22 to disengage it from the slot 23. Then slide the fixing rod 24 to slide inside the sleeve plate 21, thereby moving the two sets of sleeves 1 and adjusting the distance between them. After adjustment, the locking rod 22 can be inserted into the slot 23, and the fixing groove 25 on the outer surface of the fixing rod 24 can be engaged to fix the fixing rod 24.
[0034] Then, the two sets of housings 1 are opened, allowing the housings 1 to rotate through the hinge plate 11 and then be fitted onto the outer surface of the steel frame. Then, the connecting lugs 13 on the other side of the housings 1 are fixed by using the fixing bolts 14, washers 15 and fixing nuts 16, thereby fixing the housings 1 to the outer surface of the steel frame. At the same time, the protrusions 12 on the outer wall of the housings 1 can prevent the housings 1 from moving in a mirror image.
[0035] Then, the two steel frames with the fixing device installed are joined together, and a rubber sealing ring is placed on the opposite side of the connecting ring 3. The axial pressure ring 31 is fixed by using fastening bolts and connecting holes 33. The fixing ring 32 can gradually squeeze the rubber sealing ring to prevent the sealing ring from being excessively deformed, thereby improving the sealing effect of the sealing ring.
[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
