Anti-skid bearing seat

Abstract

This utility model relates to the field of bearing housing technology, specifically an anti-slip bearing housing, comprising a bearing housing body and bolts for fixing the bearing housing body, and a detachable anti-slip pad located at the bottom end of the bearing housing body. Pressing components are provided on both sides of the bearing housing body, and the pressing components are used to fix the anti-slip pad. After the bolts fix the bearing housing body, they press against the pressing components on both sides of the bearing housing body, thereby causing the pressing components to press and fix the anti-slip pad. When the bearing housing body is installed using bolts, the bolt head presses down on the pressing components, thereby pressing and fixing the anti-slip pad under the bearing housing body, and causing the anti-slip pad to be pressed and embedded in the pressing components. This integrated design eliminates the cumbersome steps of separately processing or pasting the anti-slip pad on the installation base surface. During installation and subsequent maintenance, the anti-slip pad, as a component pre-associated with the pressing components, can be installed and removed as a whole, which is convenient and efficient, greatly reducing installation difficulty and maintenance costs.

Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to an anti-slip bearing housing. Background Technology

[0002] As a key component supporting the rotating shaft and bearing, the stability of the bearing housing directly affects the operating accuracy, vibration and noise level, and service life of the entire transmission system. Under high load and strong vibration conditions such as heavy machinery, mining equipment, vibrating screens, and high-speed power units, the bearing housing and the mounting foundation are prone to slippage due to continuous impact and fretting. This slight relative displacement will disrupt the precise alignment of the shaft system, accelerate the loosening of connecting bolts, and thus trigger a series of chain failures such as abnormal bearing wear and seal failure, threatening the safety and stable production of the equipment.

[0003] To prevent such slippage, the industry commonly uses anti-slip pads as a solution. Traditionally, this involves adding rubber, polyurethane, or textured composite material pads between the mounting base and the bearing housing base plate. The friction generated after bolt tightening increases anti-slip capability. However, this conventional anti-slip pad installation method has the following significant drawbacks: First, anti-slip pads are mostly independent flat pads, requiring individual alignment during installation. Especially in large equipment or multi-bolt applications, it's difficult to ensure the pads don't shift position, and the bolt preload is uneven. This can easily lead to localized wrinkles or stress concentration in the pads, affecting their anti-slip performance. Secondly, the anti-slip pads and metal base plates are only pressed together on a flat surface, lacking reliable mechanical interlocking. Under long-term alternating stress, the pad material may creep or slip relative to the contact surface, resulting in a decrease in the anti-slip effect. Furthermore, while using adhesives to fix the anti-slip pads can solve the displacement problem, it introduces new issues, such as high environmental requirements for the bonding process, large dispersion in bonding strength, and extreme difficulty in cleaning residual adhesive after failure. These issues also hinder rapid equipment maintenance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings mentioned above by proposing an anti-slip bearing seat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-slip bearing seat, comprising a bearing seat body and bolts for fixing the bearing seat body, and a detachable anti-slip pad located at the bottom end of the bearing seat body, wherein pressing components are provided on both sides of the bearing seat body, and the pressing components are used to fix the anti-slip pad. After the bolts fix the bearing housing body, they press the pressing components on both sides of the bearing housing body, thereby causing the pressing components to press and fix the anti-slip pad.

[0006] Furthermore, the pressing assembly includes two receiving cavities and two mounting holes. The two receiving cavities are symmetrically opened on both sides of the bottom end of the bearing housing body. The two anti-slip pads are respectively placed inside the two receiving cavities. The mounting holes are symmetrically opened on both sides of the top end of the bearing housing body. The two mounting holes are respectively threaded through and installed in the mounting holes. The two mounting holes are respectively connected to the two receiving cavities. The pressing components for fixing the two anti-slip pads are slidably arranged on the inner sides of the two receiving cavities.

[0007] Furthermore, the pressing assembly also includes a plurality of guide holes in a ring array starting at the top of the bearing housing body. Several of the guide holes on the same side are located outside the mounting holes on the same side. Guide rods are slidably installed inside the guide holes on the same side. A ring plate one is fixedly connected to the top of the guide rod on the same side, and a ring plate two is fixedly connected to the bottom of the guide rod on the same side. A convex ring that is slidably connected to the outer wall of the mounting hole is slidably installed inside the ring plate two.

[0008] Furthermore, a plurality of damping rings are equidistantly installed on the outer surface of the convex ring.

[0009] Furthermore, a stop ring is installed on the lower side of the outer wall of the mounting hole, and the stop ring is tapered, wider at the top and narrower at the bottom.

[0010] Furthermore, a pressure plate is installed on the outer side of the second ring.

[0011] Furthermore, springs are fitted on the outer sides of several of the guide rods, with the two ends of the springs respectively abutting between the second ring and the top of the inner cavity of the receiving cavity.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when the bearing housing body is installed by bolts, the bolt head presses down on the pressing component, thereby pressing the anti-slip pad under the bearing housing body in place and squeezing the anti-slip pad into the pressing component. This integrated design eliminates the cumbersome steps of separately processing or pasting the anti-slip pad on the installation base surface. During installation and subsequent maintenance, the anti-slip pad, as a component pre-associated with the pressing component, can be installed and removed as a whole, which is convenient and efficient, greatly reducing the installation difficulty and maintenance cost.

[0013] 2. In this utility model, by setting a pressure plate, the contact area between the bolt and the anti-slip pad after the bolt is pressed down is increased, thereby avoiding stress concentration caused by direct pressure on the bolt, and thus effectively preventing the flexible anti-slip pad from producing local wrinkles and arches.

[0016] Please see Figure 1-5 This utility model provides a technical solution: an anti-slip bearing seat, including a bearing seat body 1 and bolts 2 for fixing the bearing seat body 1, and a detachable anti-slip pad 3 located at the bottom end of the bearing seat body 1. Pressing components 4 are provided on both sides of the bearing seat body 1, and the pressing components 4 are used to fix the anti-slip pad 3. After bolt 2 fixes the bearing housing body 1, it presses the pressing components 4 on both sides of the bearing housing body 1, thereby causing the pressing components 4 to press and fix the anti-slip pad 3.

[0017] Let's discuss the specific settings and functions of option 4 in detail below.

[0018] In this embodiment: the pressing component 4 includes two receiving cavities 41 and two mounting holes 42. The two receiving cavities 41 are symmetrically opened on both sides of the bottom end of the bearing housing body 1. Two anti-slip pads 3 are respectively placed inside the two receiving cavities 41. The mounting holes 42 are symmetrically opened on both sides of the top end of the bearing housing body 1. The two mounting holes 42 are respectively threaded through and installed in the mounting holes 42. The two mounting holes 42 are respectively connected to the two receiving cavities 41. The pressing component 43 for fixing the two anti-slip pads 3 is slidably arranged inside the two receiving cavities 41.

[0019] Specifically, the pressing assembly 4 also includes a number of guide holes 44 starting at the top of the bearing housing body 1 in a ring array. The number of guide holes 44 on the same side are located outside the mounting holes 42 on the same side. Guide rods 432 are slidably installed inside the guide holes 44 on the same side. A ring plate 431 is fixedly connected to the top of the guide rod 432 on the same side. A ring plate 434 is fixedly connected to the bottom of the guide rod 432 on the same side. A convex ring 435 that is slidably connected to the outer wall of the mounting hole 42 is slidably installed inside the ring plate 434.

[0020] Specifically, several damping rings 436 are equidistantly installed on the outer surface of the convex ring 435.

[0021] Specifically, a stop ring 421 is installed on the lower side of the outer wall of the mounting hole 42. The stop ring 421 is tapered, wider at the top and narrower at the bottom.

[0022] Specifically, a pressure plate 437 is installed on the outer side of the annular plate 434.

[0023] Specifically, springs 433 are fitted on the outer sides of several guide rods 432, and the two ends of the springs 433 abut against the top of the annular plate 434 and the inner cavity of the receiving cavity 41, respectively.

[0024] The effect achieved by the above components is as follows: before installing the bearing housing body 1, the anti-slip pad 3 is first placed in the receiving cavity 41, and then the bolt 2 is aligned with the mounting hole 42 and tightened. When the bolt head of the bolt 2 moves downward, it presses against the pressing member 43 and moves downward together, so that the pressing member 43 presses the anti-slip pad 3 in the receiving cavity 41 tightly. When the pressing member 43 moves downward, its lower side fits into the inner side of the anti-slip pad 3, so as to avoid wrinkles or arching caused by large layout pressure when the anti-slip pad 3 is displaced in the horizontal direction under force. When the bolt head of bolt 2 is pressed down, it first contacts the ring plate 431. When the ring plate 431 moves, the guide rod 432 is slidably installed in the guide hole 44 and the convex ring 435 is slidably installed on the outer wall of the mounting hole 42, which plays a guiding role. When the convex ring 435 is pushed, its lower side is pressed into the pre-processed inner cavity of the anti-slip pad 3. The damping ring 436 on the outer side of the convex ring 435 enhances the damping effect between the convex ring 435 and the anti-slip pad 3, and avoids the gap between the inner side of the anti-slip pad 3 and the convex ring 435 for movement. The stop ring 421 installed on the lower side of the outer wall of the mounting hole 42 prevents the damping ring 436 from detaching from the outer wall of the mounting hole 42. The stop ring 421 is tapered, wider at the top and narrower at the bottom. When the anti-slip pad 3 is placed in the receiving cavity 41, the narrow bottom end of the stop ring 421 facilitates the positioning of the inner cavity of the anti-slip pad 3. In addition, the wide top end of the stop ring 421 can be damped and connected to the inner side of the anti-slip pad 3, which plays a preliminary positioning role. By setting the pressure plate 437, the contact area between the bolt 2 and the anti-slip pad 3 after the bolt 2 is pressed down is increased, thereby avoiding stress concentration caused by direct pressure on the bolt 2, and effectively preventing the flexible anti-slip pad 3 from producing local wrinkles and arches.
