Embodiment 1
[0040] like Figure 1-Figure 5 As shown, a vacuum oil immersion device for powder metallurgy bearing lubrication includes an outer container 1, a rotary oil immersion chamber 2, an ultrasonic generator 3, a sealing cover 4 and a vacuuming pipeline 5, and the rotary oil immersion chamber 2 is inclined It is installed in the inner cavity of the outer container 1, and an ultrasonic medium is filled between the rotary oil immersion inner chamber 2 and the outer container 1. The outer container 1 has an opening facing upward and is arranged vertically, and the rotary oil immersion inner chamber 2 is inclined and arranged. The inner cavity of the outer container 1. The rotary oil-immersed inner chamber 2 includes a rotary frame 21 and an inner container 22, the inner container 22 is used for holding lubricating oil and bearings, and the rotary frame 21 is used for connecting the inner container 22, the inner container 22 and the outer container 22. The container 1 is connected, and...
Embodiment 2
[0053] like Image 6 As shown in the figure, a vacuum oil immersion device for powder metallurgy bearing lubrication disclosed in this embodiment is different from the above-mentioned Embodiment 1 in that a spacer 7 is arranged on the outer side of the bottom of the outer container 1, and the spacer 7 is provided with a The outer container 1 has an inclined inclined surface, and the angle of the inclined surface is fixed. The inner container 22 is parallel to the outer container 1 , and the bottom surfaces of the outer container 1 and the inner container 22 are inclined by 25°-55° relative to the horizontal line, so that the lubricating oil in the inner container 22 and the inner container 1 The ultrasonic medium can form an inclined liquid level, and the bearing in the inner container 22 can contact with the side wall of the inner container 22, and the center of gravity of the inner container 22 will shift with the position of the lubricating oil and the bearing. The liquid ...
Embodiment 3
[0056] like Figure 7-Figure 8 As shown in the figure, a vacuum oil immersion device for powder metallurgy bearing lubrication disclosed in this embodiment is different from the above-mentioned Embodiment 2 in that in order to ensure the "turbulent agitation" effect of the lubricating oil and the bearing, the reliability of the oil immersion process is improved. It is easy to control the inclination angle of the rotary oil immersion inner chamber 2 and the outer container 1. In this embodiment, the angle of the inclined pad surface is adjustable. Specifically, the cushion block 7 includes a support member, and the angle of the inclined cushion surface is adjusted by the support member.
[0057] The support member includes an outer frame 71, the top of the outer frame 71 is open, the upper rotating shaft 72 is installed in the outer frame 71 through a ball bearing, and a linear slide rail 73 is provided on the opposite side of the inclined pad surface. The rail 73 is parallel ...
