Description

  The present invention relates to an apparatus for applying lubricating oil to a machine part that transmits power, such as a motor, such as a roller chain.

  In a three-dimensional parking lot, a pallet type automatic warehouse, etc., a roller chain or the like is used as means for transmitting a rotational force generated by a driving device such as a motor, and lifts and lowers a load of about 1 t. The roller chain includes a roller, a bush, an inner plate, an outer plate, and a shaft, and extremely strong frictional force acts on each of the components. Lubricating oil is periodically applied to the roller chain in order to reduce mechanical wear due to frictional force between the components and when engaging with the sprocket, and to facilitate transmission of power from the drive unit. The

  The application of the lubricating oil is performed by including lubricating oil between brush brushes and bringing the brush brush containing the lubricating oil into contact with a roller chain. However, since it is necessary to apply the lubricating oil to the entire roller chain that constitutes a three-dimensional parking lot, a pallet type automatic warehouse, etc., there is a problem that uneven coating tends to occur due to the experience of workers. In addition, there is a problem that excess oil generated by uneven coating of lubricating oil contaminates the load in the three-dimensional parking lot and the pallet type automatic warehouse.

  Further, during the operation of applying the lubricating oil in a state where the roller chain is driven, it is not preferable that an operator touches the roller chain because it is very dangerous. On the other hand, when lubricating oil is applied to a part that cannot be applied when the roller chain is stationary, for example, a roller chain that is driven at a location that is not accessible by workers working on the ground, the roller chain is driven up and down. However, although the operation | work which apply | coats the said lubricating oil is performed, it is unpreferable since it is often accompanied by the work of an operator's high place and is dangerous. In addition, when applying the lubricating oil while driving the roller chain up and down, it is necessary to have at least two operators, such as the three-dimensional parking garage, and an operator who applies the lubricating oil. There is a problem.

  Patent Document 1 discloses an oil application device for a roller chain that can reliably prevent dripping and scattering of the lubricating oil and uniformly apply an appropriate amount of lubricating oil to a predetermined portion of the roller chain. . The oil application apparatus disclosed in Patent Document 1 has a structure in which an application member made of compression felt is provided at a lower position of a roller chain, and an abutting portion that comes into contact with a roller of the roller chain is provided above the application member. Have

  However, the oil application device does not have a structure for applying the lubricating oil to the outer plate of the roller chain, and does not have a configuration for removing the surplus portion of the lubricating oil once applied. For this reason, there is a problem that the lubricating oil hardly spreads over the entire components of the roller chain, and coating unevenness is likely to occur, and that the excess amount increases when the amount of the lubricating oil applied is increased in order to prevent the coating unevenness. Such a problem becomes more prominent as the size of the roller chain increases.

  In FIG. 1, the lubricating oil application device 1 applies lubricating oil to a roller chain that is driven in the horizontal direction with respect to the ground. However, the lubricating oil application device 1 according to the embodiment of the present invention is not in the horizontal direction. Lubricating oil can be applied even to a driving roller chain.

  For example, when lubricating oil is applied to a roller chain that is driven in the vertical direction, the uppermost end or a part of the uppermost surface of the rotating case 2 is connected to one end of a wire rope, and is provided on a vertically standing column or the like. The posture of the rotating case 2 can be kept constant by hanging the wire rope around the pulley and hanging a counterweight on the other end of the wire rope. Alternatively, a coil or the like is provided in the vicinity of the chain insertion ports 10a and 10b between the bottom portion of the rotating case 2 and the support column that is erected vertically, and when the lubricating oil application portion contacts the roller chain, You may reduce that an excessive pressure and frictional force act on the said lubricating oil application part.

The roller chain 100 is applied with lubricating oil by coming into contact with the lubricating oil applying portion, and the lubricating oil scraping portion is configured so that the lubricating oil once applied is held on the surface of the roller chain 100. A uniform oil film is formed.

  In the present embodiment, the lubricating oil is stored in the oil tank 40 and is supplied by dropping from the oil tank 40 to at least one of the lower roller chain 100 and the lubricating oil application unit. In a simple manner, a small hole is formed in the bottom plate of the oil tank 40, and the lubricating oil can be dropped in the form of oil droplets onto the component parts of the roller chain from the small hole. The size and number of the small holes are determined in consideration of the amount of lubricating oil supplied to the roller chain 100, the viscosity of the lubricating oil, and the like.

  In the present embodiment, the lubricating oil is supplied into the oil tank 40 by supplying the lubricating oil into the oil tank 40 from the inlet 41 formed on the ceiling of the oil tank 40. The oil tank 40 is fixed on the case upper portion 2 a of the rotating case 2 using bolts 43 and 44.

  The lubricating oil application section includes roller surface application sections 21a, 21b and 21c for applying lubricating oil from the upper side of the roller 130 of the roller chain, and a roller surface application section 22a for applying lubricating oil from the lower side of the roller 130, 22b and 22c. The roller surface application portions 21a, 21b, and 21c and the roller surface application portions 22a, 22b, and 22c may be made of any material that can contain lubricating oil, and are conventionally made of nylon. It is not limited to a brush for oil application, and a porous body formed in a columnar shape such as a sponge for oil application can also be used.
