Description

Technical Field

[0001] This utility model relates to the technical field of bearing cap testing, and specifically to a bearing cap testing fixture. Background Technology

[0002] Bearing preload margin refers to the compression space reserved during bearing assembly to ensure that the bearing ultimately reaches the preload state required by the design. In the field of precision machinery assembly, the accuracy of bearing preload margin directly affects the stability and lifespan of equipment operation. Traditional testing methods rely on manual experience or complex equipment, which are cumbersome and inefficient.

[0003] When checking the preload allowance of a bearing, it is usually necessary to remove the bearing cover to expose the bearing for inspection. However, multiple disassembly and adjustment will undoubtedly prolong the assembly time. A feeler gauge is usually used for measurement, but feeler gauges cannot measure accurately, resulting in data deviation and affecting the control of the preload. Utility Model Content

[0004] To address the aforementioned issues, namely the cumbersome disassembly process and insufficient testing accuracy during inspection, this utility model proposes a bearing cover testing fixture, which includes a cover body. A locking hole and a measuring hole are provided on the front surface of the cover body. The locking hole is used to lock the cover body, and the measuring hole is used to install dial indicator contacts.

[0005] A further feature of this invention is that a threaded hole is provided on the pressure cap body corresponding to the measuring hole, the threaded hole is perpendicular to the measuring hole, and the threaded hole is connected to the measuring hole.

[0006] A further feature of this invention is that two locking holes and two measuring holes are provided, with the two locking holes arranged horizontally and the two measuring holes arranged vertically.

[0007] The beneficial effects of this utility model are as follows:

[0008] By using the threaded hole and the measuring hole, a dial indicator can be fixed to the gland body, allowing the dial indicator's contacts to continuously monitor the bearing's preload. This enables measurement to be completed in a single setup, avoiding multiple disassemblies of the gland body, simplifying the inspection process, and improving assembly efficiency. Furthermore, using a dial indicator allows for more precise measurements. Attached Figure Description

[0012] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] This utility model proposes a bearing cover testing fixture, including a cover body 1. The front surface of the cover body 1 is provided with a locking hole 11 and a measuring hole 12. The locking hole 11 is used to connect the cover body 1 to the equipment with bolts. The measuring hole 12 is used to install the dial indicator contact. That is, the contact rod of the dial indicator can be inserted into the measuring hole 12, and the contact contacts the outer ring of the bearing, thereby realizing the measurement of the reserved compression space.

[0014] A threaded hole 13 is provided on the side wall of the pressure plate body 1. The threaded hole 13 is set to correspond to the measuring hole 12 and is perpendicular to the measuring hole 12. The threaded hole 13 is connected to the measuring hole 12. A set screw is connected to the threaded hole 13. The set screw is used to press the contact point of the dial indicator, thereby achieving the purpose of fixing the dial indicator and the pressure plate body together.

[0015] There are two locking holes 11 and two measuring holes 12. The two locking holes 11 are arranged left and right, and the two locking holes are symmetrical about the center of the pressure cap body 1. The two measuring holes 12 are arranged up and down, and the two measuring holes 12 are also symmetrical about the center of the pressure cap body 1.

[0016] It should be noted that the gland body 1 is made of 45# steel and heat-treated to a hardness of HRC40-45 to ensure its wear resistance and rigidity. The diameter of the two measuring holes 12 is set to 9mm, and the diameter of the two locking holes 11 is set to 11mm. M10 bolts are used to engage with the locking holes 11 to achieve a fixed connection of the gland body 1. M6 set screws are fitted into the two threaded holes 13 to tighten the dial indicator.

[0017] In summary, this utility model, through the cooperation of the threaded hole 13 and the measuring hole 12, enables the dial indicator to be fixed to the pressure cap body 1, thereby allowing the dial indicator contacts to continuously detect the preload allowance of the bearing. This further allows for measurement to be completed in a single clamping operation, avoiding multiple disassemblies of the pressure cap body 1, simplifying the testing process, and improving assembly efficiency. Simultaneously, using a dial indicator for testing allows for more accurate measurements.
