Device and method for measuring sealing state of bearing

Abstract

The invention discloses a device and a method for measuring the sealing state of a bearing. The measuring device comprises a measuring table base and an adjustable magnetic force mounting and clamping meter frame arranged on the measuring table base, wherein a measuring apparatus is arranged above the bearing on the adjustable magnetic force mounting and clamping meter frame; and a right angle baffle ruler and a standard block are fixedly arranged on the measuring table base. The detecting method comprises the following steps of tightly making the bearing close to the right angle of the right angle baffle ruler, adjusting a pointer of the measuring apparatus to a sealing component point B through the adjustable magnetic force mounting and clamping meter frame, moving the sealing component from the point B to the point A through the standard block under the condition that the adjustable magnetic force mounting and clamping meter frame is fixed, and reading on the measuring apparatus. The planeness, internal framework deformation, inclination and pressing degree of a bearing sealing ring which is pressed in can be precisely detected through the combination of the adjustable magnetic force mounting and clamping meter frame and the standard block, and through reading on the measuring apparatus, the control on the starting torsion of the bearing is ensured, the change of the bearing temperature is reduced, the sealing performance of the bearing is greatly improved, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a bearing sealing performance measurement device and a method thereof. Background technique [0002] As we all know, bearings are an important part of contemporary mechanical equipment. With the change of bearing operating conditions, the requirements for bearing sealing performance are getting higher and higher. As a key component of sealed bearings, sealing rings are pressed into bearings. The final state plays an important role in the overall sealing performance of the sealed bearing. At present, although many bearing manufacturers know this, they are still relatively deficient in detection methods and means for sealing rings. They can only detect the appearance (visual) and basic dimensions (such as inner and outer diameters, thickness) of sealing rings. Pressed into the bearing and the state cannot be guaranteed, and finally the bearing will have poor ...

At present, although many bearing manufacturers know this, they are still relatively deficient in detection methods and means for sealing rings. They can only detect the appearance (visual) and basic dimensions (such as inner and outer diameters, thickness) of sealing rings. Pressed into the bearing and the state cannot be guaranteed, and finally the bearing will have poor sealing and bearing failure when the customer uses it
