Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1~5 As shown, the sliding bearing designed in the present invention includes a bearing seat 200 and a bearing cap with a damping material layer. in:

[0021] The bearing cap includes a bearing cap fastening portion 100 , a bearing cap shaft hole portion 102 and a damping material layer 101 separated from each other.

[0022] The middle and lower part of the bearing cover shaft hole 102 is provided with a shaft hole notch 103, and the left and right parts of the bearing cover shaft hole 102 are symmetrical "concave" shaped structures, specifically including an upper flange 104, a groove 105 and a lower convex Edge 106 has three parts. The outer spacing of the lower flanges 106 at the left and right parts of the bearing cover shaft hole 102 is greater than the outer spacing of the upper flanges 104 at the left ...

Abstract

The invention discloses a bearing cover with a damping material layer and a sliding bearing. The bearing cover comprises a bearing cover fastening part, a bearing cover shaft hole part and a damping material layer; one part of the damping material layer is arranged between the bearing cover fastening part and the bearing cover shaft hole part, and divides the bearing cover fastening part and the bearing cover shaft hole part into two parts which are not in contact with each other; and the other part of the damping material layer covers the lower portion of the bearing cover shaft hole part anda mounting surface adjacent to a bearing seat, so that the bearing cover shaft hole part is not in direct contact with the bearing seat after being mounted on the bearing seat. The sliding bearing comprises the bearing cover. According to the bearing cover with the damping material layer, the damping material layer is arranged between the bearing cover shaft hole part and the bearing cover fastening part and between the bearing cover shaft hole part and the bearing seat, so that the transmission path of structural vibration from a bearing cover to the bearing seat is completely isolated, thestructural vibration is buffered and absorbed in the damping material layer and can be greatly attenuated, and the purposes of vibration isolation and noise reduction are achieved.

Description

technical field [0001] The invention relates to a sliding bearing, in particular to a bearing cover with a damping material layer and the sliding bearing. Background technique [0002] Plain bearings are commonly used to support and lubricate shaft parts. The shaft parts bear the dynamic radial load caused by the driven parts when they rotate. The fluctuating radial load and the unbalanced inertial force of the shaft parts make the shaft journal of the shaft parts contact with the shaft hole material and transmit the fluctuating contact load. When it is bad, the jump of the journal in the shaft hole will occur. This fluctuating radial contact load or the runout of the journal in the shaft bore can generate large structural vibrations in the plain bearing. In many cases, the journal is in contact with the bearing cover of the sliding bearing, so the bearing cover of the sliding bearing is an important structural vibration transmission path. The usual sliding bearings and b...
