Description

  The present invention relates to a storage device for a bearing structure, a support structure with a storage device, and a storage method for the support structure.

2. Description of the Related Art Conventionally, as shown in, for example, Patent Document 1 below, a support provided with a pair of upper and lower support structures that are separately fixed to the upper structure and the lower structure and are slidably disposed in the horizontal direction. The device is known.

Japanese Patent No. 3563669

  However, in the conventional bearing device, for example, the timing at which each bearing component is completed after the lubricant is held on the sliding surface portion until the bearing device is installed between the upper structure and the lower structure. When the bearing components need to be stored separately for a long period of time due to their different from each other, the lubricant held on the sliding surface portion is easily detached from the sliding surface portion, and the dynamic friction coefficient of the sliding surface portion is increased. It may fluctuate greatly and affect the quality of the bearing device.

  In addition, even if the lubricant is detached from the sliding surface portion, in order to easily stabilize the dynamic friction coefficient of the sliding surface portion, the lubricant is moved from the surface of the sliding surface portion to the sliding surface portion. It is conceivable to increase the amount of the lubricant held on the surface side portion by holding it until it is far away in the thickness direction. However, in this case, for example, it is necessary to add an additive to the lubricant in order to provide the lubricant with high permeability and dispersibility, or to inject the lubricant while applying pressure to the surface side portion of the sliding surface portion. There is a problem that it takes time and effort.

  The present invention has been made in view of the above-described circumstances, and its purpose is to store a bearing structure capable of suppressing the detachment of the lubricant from the sliding surface portion over a long period of time by a simple operation. Is to provide the ingredients.

In order to solve the above problems, the present invention proposes the following means.
The storage device for a bearing structure according to the present invention includes a sliding member among a pair of upper and lower bearing structures that are separately fixed to the upper structure and the lower structure and are slidable relative to each other in the horizontal direction. A storage device for a bearing structure for storing one bearing structure in which a liquid lubricant is held on the surface side portion of the moving surface portion, and the lubricant is stained by holding and pressing the lubricant. The holding member that comes out, the liquid-impervious member on which the holding member is placed, and the holding member sandwiched between the liquid-impervious member and the surface of the sliding surface portion from the opposite side of the holding member A liquid permeable member with which a side portion abuts, wherein the holding member and the liquid permeable member are lubricated from the holding member in a state where the holding member is pressed through the liquid permeable member. It takes to reach saturation after the agent begins to exude It is configured so that the time required to reach saturation after the start of the seepage from the liquid-permeable member of the lubricant that has oozed out from the holding member and into the liquid-permeable member is longer than the time. It is characterized by.

  Further, the support structure with storage device according to the present invention is a pair of upper and lower support structures that are separately fixed to the upper structure and the lower structure and are slidable relative to each other in the horizontal direction. A bearing structure in which a liquid lubricant is held on the surface side portion of the sliding surface portion, and a storage tool for the bearing structure, and the one support structure on the storage tool of the bearing structure. The body is installed such that the surface side portion of the sliding surface portion comes into contact with the liquid-permeable member from the opposite side.

  The bearing structure storage method according to the present invention includes a pair of upper and lower support structures fixed to the upper structure and the lower structure and slidably disposed in the horizontal direction. A storage method of a bearing structure for storing a bearing structure in which a liquid lubricant is held on the surface side portion of the sliding surface portion, and the one bearing structure on a storage tool of the bearing structure It has the installation process which installs so that the surface side part of the said sliding face part may contact | abut to the said liquid-permeable member from the said opposite side.

  According to these inventions, when the one support component is installed on the storage device of the support component so that the surface side portion of the sliding surface portion contacts the liquid-permeable member from the opposite side, the one The holding member is pressed through the liquid-permeable member due to its own weight, and the lubricant soaks out of the holding member and then penetrates into the liquid-permeable member and permeates the liquid-permeable member. The seepage from the liquid-permeable member is supplied to the surface side portion of the sliding surface portion, and the detachment of the lubricant held on the surface side portion is suppressed. At this time, from the liquid-permeable member of the lubricant that has oozed out of the holding member and soaked into the liquid-permeable member than the time required to reach saturation after the start-up of the lubricant from the holding member. Since the holding member and the liquid-permeable member are configured so that it takes a long time to reach saturation after the start of bleeding, the lubricant that has oozed out of the holding member is removed from the liquid-permeable member. Instead of exuding all at once, it gradually exudes over time and continues to be supplied to the surface side portion of the sliding surface portion over a long period of time.

  From the above, it becomes possible to continue supplying the lubricant to the surface side portion of the sliding surface portion over a long period of time by a simple operation of installing the one supporting structure on the storage device of the supporting structure, The detachment of the lubricant from the sliding surface portion can be suppressed over a long period.

  Moreover, the storage device for a support structure according to the present invention may include a covering member that is detachably fixed to the liquid-permeable member so as to cover the liquid-permeable member from the opposite side.

  In this case, since the covering member is provided, the holding member is formed by covering the liquid-permeable member with the covering member until the one supporting structure is installed on the storage device of the supporting structure. It is possible to suppress the lubricant held in the liquid from leaking outside through the liquid-permeable member. As a result, the lubricant can be reliably held by the holding member, and the detachment of the lubricant from the sliding surface portion can be reliably suppressed over a long period of time.

  Further, in the storage device for a support structure according to the present invention, the holding member is smaller than the liquid-impervious member and the liquid-permeable member in a plan view of the storage device of the support structure, and these The liquid-impervious member and the liquid-permeable member are disposed inside the outer peripheral edge, and the liquid-impervious member and the liquid-permeable member are joined to each other on the entire periphery. The holding member may be sandwiched.

  In this case, since the liquid impervious member and the outer peripheral edge portions of the liquid permeable member are joined to each other over the entire circumference, the liquid impermeable member and the liquid permeable member sandwich the holding member. The lubricant that exudes from the holding member can be prevented from leaking outside through the space between the liquid-permeable member and the liquid-impermeable member. As a result, the lubricant can be reliably supplied to the surface side portion of the sliding surface portion, and the detachment of the lubricant from the sliding surface portion can be reliably suppressed over a long period of time.

  According to the present invention, the detachment of the lubricant from the sliding surface portion can be suppressed over a long period of time by a simple operation.
