Abstract
Description
Technical Field
[0001] The utility model provides a lubricating device for a vertical reducer, belonging to the technical field of reducer lubrication. Background Art
[0002] When the oil level of the vertical reducer is low, the gears and bearings at the top of the reducer are poorly lubricated and easily damaged; when the lubricating oil is filled, the lubricating oil will expand due to heat when the reducer is running, and the lubricating oil will easily come out of the breather cap, which will easily pollute the environment; at the same time, after the lubricating oil comes out, the oil level in the oil tank will be lowered, and the gears and bearings at the top of the reducer will not be lubricated and easily damaged. At the same time, the oil level glass sight glass designed for the vertical reducer is generally lower than the top bearing of the reducer. When the oil level is low, the top bearing of the reducer has already been poorly lubricated. Even if the oil level is low, some lubricating oil will come out due to heat during operation, so the oil level will be lower, and the reducer will be easily damaged over time.
[0003] Therefore, it is necessary to provide a new lubrication device for a reducer to solve the above technical problems. Utility Model Content
[0004] In order to overcome the deficiencies in the prior art, the utility model aims to solve the technical problem of providing an improvement in the hardware structure of a lubricating device for a vertical reducer.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lubricating device for a vertical reducer, comprising a joint connected to the oil tank of the vertical reducer, the joint is connected to an oil inlet pipe through an elbow, the oil inlet pipe is installed at the bottom of an expansion oil tank, an oil outlet pipe is installed at the top of the expansion oil tank, a dustproof pressure breathable cap is installed at the top of the oil outlet pipe, and an oil dipstick is also installed at the center of the expansion oil tank;
[0006] The installation positions of the oil inlet pipe and the oil outlet pipe are staggered up and down;
[0007] The oil inlet pipe is curved.
[0008] The oil inlet pipe is composed of at least two seamless steel pipes, which are connected with elbows.
[0009] The expansion oil tank is welded and has a cube or column shape.
[0010] The installation position of the expansion oil tank avoids the transmission motor of the vertical reducer.
[0011] The oil inlet pipe and the oil outlet pipe are welded on the expansion oil tank by using seamless steel pipes.
[0012] The oil inlet pipe uses an elbow to connect two sections of seamless steel pipes, and the inlet and outlet of the two elbows are 180 degrees.
[0013] One end of the joint is connected to the vertical reducer, and the other end is a pipe thread connection elbow.
[0014] The oil dipstick is provided with a scale and is marked with an oil level lower limit and an oil level upper limit.
[0015] The sizes of the expansion oil tank and its associated pipe fittings are cut and installed according to the actual sizes of the vertical reducer and the motor, and pickling is performed before installation.
[0016] The beneficial effects of the utility model compared with the prior art are:
[0017] When the vertical reducer is installed with an expansion tank, the oil level is generally controlled to be higher than the reducer, so that the bearings and gears at the top of the reducer can be fully lubricated. In this way, the oil level is also higher than the oil level sight glass designed on the side of the reducer. In this way, the oil level sight glass can only be used to check the quality of the lubricating oil.
[0018] Generally, vertical reducers are mostly used for heavy loads, with compact structures, small reducer oil tanks, less lubricating oil, and easy to heat up. The expansion oil tank of the utility model controls the oil level through the oil dipstick to ensure that the oil level is always higher than the reducer. Although the high oil level of the reducer is also likely to cause the reducer to heat up, the process of the lubricating oil in the reducer heating up and expanding to the expansion oil tank is actually a heat dissipation process, which can achieve the heat dissipation of the reducer.

[0023] like Figure 1 and 2 As shown, the utility model provides a lubrication device for a vertical reducer, including a joint 7 connected to the vertical reducer oil tank, a first section elbow 6 is installed on the top of the joint 7, the first section elbow 6 is connected to the first section oil inlet pipe 5, the first section oil inlet pipe 5 is connected to the second section oil inlet pipe 5 through the second section elbow 6, the second section oil inlet pipe 5 is connected to the bottom of the expansion oil tank 4, the top of the expansion oil tank 4 is connected to the oil outlet pipe 2, the center of the expansion oil tank 4 is also installed with an oil dipstick 3, and a dustproof pressure vent cap 1 is provided on the top of the oil outlet pipe 2.
[0024] Specifically, the purpose of the dust-proof pressure vent cap 1 is to balance the internal and external pressures of the vertical reducer. When the internal pressure of the reducer is greater than the outside air pressure, the dust-proof pressure vent cap 1 releases pressure to make the internal and external pressures of the reducer the same; secondly, the dust-proof pressure vent cap 1 is self-locking after pressure relief, which can prevent external dust from entering the reducer and contaminating the reducer lubricating oil.
[0025] Specifically, the expansion oil tank 4 is welded and can be round or square. The oil inlet pipe 5 and the oil outlet pipe 2 should be staggered up and down when welding. It can be imagined that when the lubricating oil in the vertical reducer oil tank expands, the oil level rises along the oil inlet pipe 5 to the expansion oil tank 4, and the expansion pressure of the lubricating oil drops suddenly, so the pressure entering the oil outlet pipe 2 of the expansion oil tank will drop significantly.
[0026] Specifically, in order to reduce the expansion pressure of the reducer lubricating oil, the oil inlet pipe 5 can be intentionally designed to be bent, such as an "S" shape, with twists and turns. Generally, the expansion oil tank 4 is positioned away from the transmission motor as much as possible.
[0027] Specifically, there is a scale on the oil dipstick 3 installed in the center of the expansion oil tank 4. When the lubricating oil expands and the oil level is lower than the lower limit of the oil dipstick, the oil is replenished in time through the mounting hole of the oil dipstick 3; when the lubricating oil expands and the oil level is higher than the upper limit of the oil dipstick, the oil quality is checked through the oil level sight glass on the side of the reducer to see if water has entered. If it has deteriorated seriously, the lubricating oil needs to be replaced in time.
[0028] Specifically, the oil inlet pipe 5 is arranged according to the actual size, has two or more sections, and is connected together with an elbow 6. The connection between the vertical reducer oil tank and the elbow 6 requires the elbow 7 to be processed according to the actual size.
[0029] It should be noted that the expansion oil tank 4 and its accessories must be pickled before installation, and the pickling standard complies with GB / T8923-1988.
[0030] According to the thread of the refueling hole of the vertical reducer, the utility model processes a non-standard joint 7 (one end is connected to the vertical reducer, and the other end is a pipe thread), and connects two or more sections of seamless steel pipes through an elbow 6 at the end of the pipe thread. The inlet and outlet of the two elbows are 180 degrees, and the outlet of the elbow 6 is connected to the oil inlet pipe 5 of the expansion oil tank 4. The oil outlet pipe 2 of the expansion oil tank 4 is staggered with the oil inlet pipe 5. The head of the oil outlet pipe 2 of the expansion oil tank is provided with a dustproof pressure vent cap 1, which can only be discharged but not inlet. There is an oil dipstick 3 at the center of the expansion oil tank 4, and the oil dipstick 3 has a scale. When the vertical reducer is running, the oil level can be checked. If the oil level in the expanded state is lower than the oil dipstick scale, it is necessary to add oil through the oil dipstick hole to prevent the vertical reducer from lacking oil. If the oil level in the expanded state is higher than the oil dipstick scale, it is necessary to check whether the lubricating oil has water in it. If the deterioration is serious, the lubricating oil needs to be replaced in time.

Except for special instructions in the embodiments, the specific connection relationship can bring corresponding technical effects and solve the technical problems raised by the utility model without relying on the execution of corresponding software programs.
