Embodiment Construction
[0009] Now in conjunction with accompanying drawing, the present invention will be further described. The names of the serial numbers in the figure are: inner ring 1, outer ring 2, steel ball 3, retainer 4, sealing ring 5.
[0010] like figure 1 , figure 2 As mentioned above, the main difference between this bearing and the existing known bearings is that a sealing ring is installed between the inner ring and the outer ring, and the sealing ring is placed between the inner ring and the outer ring as an interference fit, and the interference is 0.2~ 0.3mm. In addition, when the inner ring is processed by turning, the inner ring is processed into a straight-through type. The straight-through type has no steps, and the roughness of the outer diameter of the inner ring is strictly controlled Ra≤0.25um. The sealing ring is made of NBR material, and the sealing ring and the inner ring are double-lip sealed. By increasing the width of the double-lip seal, the contact area between...

The invention relates to a bearing, in particular to a brake bearing and a method for increasing friction force thereof, which aim to solve the technical problem of single function of the similar bearing. The key points of the design are that: the magnitudes of interference between a seal ring and an inner ring, and between the seal ring and an outer ring are 0.2 to 0.3mm, and the seal ring and the inner ring are sealed in a double-lip way. The method for increasing the friction force comprises the following steps of: improving wear resistance of the seal ring, and increasing the width of thedouble-lip seal; during lathing of the inner ring, processing the inner ring to obtain a through inner ring, and strictly controlling the roughness Ra of the outer diameter of the inner ring during grinding to be less than or equal to 0.25 mu m; and increasing the contact area of the seal ring and the inner ring by increasing the width of the double-lip seal, and increasing the friction force to improve the brake effect, wherein the contact area and the interference magnitude of the inner ring and the seal ring ensure that friction torque generated between the inner ring and the seal ring is 200 to 400 gcm. The brake bearing and the method for increasing the friction force thereof are suitable for matching of equipment needing quick stalling operation in the conventional products or structural improvement of the similar bearing.
Description
technical field [0001] The invention relates to a bearing, which is a method for increasing the frictional force of a brake bearing with a brake function. Background technique [0002] Brake bearings have a wide range of applications. For example, the bearings of electric meat grinders are required to stop the motor quickly when the machine is stopped, so the brake bearings can realize the above functions. At present, general bearings can only play the role of support and guidance, but do not have the function of braking. If the general bearings can also be used as brake bearings, it is necessary to make corresponding improvements to the general bearings. Contents of the invention [0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide a method for increasing the friction of a brake bearing with a brake function in the field, so as to solve the technical problem of the single function of the existing similar bearings. The ...
