Abstract
The utility model relates to an oil-economizing reduction gear box which comprises an output axis, an input axis and a box body; wherein the end parts of the two axis are respectively provided with an axis end cap; and the outer side of the input axis end cap is provided with a sealing slips, wherein the lower part of the sealing slips is provided with an oil leakage hole which is communicated with the inside of the box body through an overflow pipe. The utility model realizes the recycling of the leaked oil, saves the lubrication, and ensures the cleanness of the equipment as well as avoids the environmental pollution. In addition, the utility model also avoids the damage caused by excessive oil leakage to the slowing-down parts.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of speed reducer that has the leakage of oil recovering device, can save lubricant oil.
Background technique
Speed reducer is widely used in the industrial production field as a kind of retarding device.Common speed reducer has gear type, worm-gear type, planet cycloid formula etc.In order to reduce friction, the good heat radiating between the deceleration component in the case, generally in speed reducer, inject lubricating oil.The input and output axle of speed reducer passes casing, extends to the casing outside, is connected with the parts of its driving arrangement and his equipment.Between casing and output, input shaft, seal arrangement is set, for example filled or add seal ring at hubcap.When speed reducer was worked, the deceleration component of box house ran up, and drove input, output shaft rotation, and especially input shaft rotational speed is higher, makes the actual sealing effect of above-mentioned conventional seals mode not good.Not only need often to change seal arrangement, and caused the leakage waste of lubricant oil in the casing.
The main cause of the axle head leakage of oil of speed reducer is, retarding device is after long-time running, and wearing and tearing have in various degree all taken place for axle surface and oil sealing, and the pressure outside a little higher than casing of pressure in this moment speed reducer is so lubricant oil is easy to reveal from axle head.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of fuel-economizing speed reducer is provided, and this speed reducer can reclaim the leakage of oil of input, output shaft.
The technical solution adopted in the utility model is: a kind of fuel-economizing speed reducer, include output shaft, input shaft and casing, end at described axle is respectively arranged with hubcap, the described input shaft end cap outside is provided with the sealing slips, sealing slips bottom has oil leaking hole, and this oil leaking hole is communicated with described box house by return tube.
Wherein, described sealing slips is provided with oil scraping plate, and this oil scraping plate has through hole, and the diameter of this through hole is less than the diameter of axle that passes this oil scraping plate.
Wherein, back leakage connection is installed on the oil leaking hole, this joint is connected with described return tube.
Wherein, described casing is provided with the plug of draining the oil, described return tube with described on the plug of draining the oil be connected, be communicated with described box house.
Wherein, the hubcap of the described output shaft outside also is provided with the sealing slips, and the sealing slips is communicated with described box house by return tube.
The fuel-economizing speed reducer that provides according to the utility model, at speed reducer hubcap arranged outside sealing slips, oil scraping plate, between sealing slips and speed reducer hubcap, form a holding space, this space and deceleration box inner space are separated, and make pressure and external pressure basically identical in this space.By oil scraping plate the leakage of oil in the casing is retained in the holding space of sealing slips, the lubricant oil that spills flows back to box house by return tube again.Realize the recovery of leakage of oil, saved lubricant oil, ensured the cleaning of equipment, avoided environmental pollution.In addition, the infringement of also avoiding that causes owing to excessive leakage of oil to deceleration component.
Description of drawings
Fig. 1 is the structural representation of the utility model fuel-economizing speed reducer;
Fig. 2 is the structural representation that seals slips and oil scraping plate among Fig. 1;
Fig. 3 is Fig. 2 plan view.
Embodiment
The utility model fuel-economizing speed reducer referring to Fig. 1, includes casing 11, and casing 11 inside are provided with deceleration component, are marked with lubricant oil in casing 11, and lubricant oil need make the lubricant oil liquid level be in the position of fluid position 8 according to the design of speed reducer.Speed reducer is provided with the drain the oil plug 9 and the plug 10 of draining the oil down, when lubricant oil injection amount during above fluid position 8, opens the plug 9 of draining the oil, and unnecessary lubricant oil is emitted, and when needs more during oil change, opens down the plug 10 of draining the oil, and lubricant oil is emitted.
Be provided with sealing slips 2 in hubcap 7 outsides, the structure of sealing slips 2 is seen Fig. 2, Fig. 3, installs for convenience, it can be processed as the branch body structure.Be provided with oil scraping plate 6 in sealing slips 2 upper opening positions, oil scraping plate 6 can be made of malthoid, and its opening diameter is slightly less than the diameter of axle, so that closely cooperate with it when axle rotates, will scrape attached to the leakage of oil on the axle.Bottom at sealing slips 2 has oil leaking hole, is provided with oil returning pipe joint 3 on oil leaking hole, and oil returning pipe joint 3 is connected with return tube 4.Return tube 4 is divided into left side return tube and right side return tube two-part, the right side return tube is arranged on output shaft 12 1 sides, the left side return tube is arranged on input shaft 13 1 sides, the left side return tube is with after the right side return tube is connected by return tube threeway 5, be connected with the plug 9 of draining the oil on the casing 1, be in and casing 1 connected state.Return tube 4 also can directly be communicated with other aperture positions of casing 1, as long as this aperture position is lower than the position of the oil leaking hole of sealing slips 2, can guarantee that the leakage of oil backflow gets final product.
When speed reducer was worked, lubricant oil spilt from axle head, and a part is fed directly in the space that forms between hubcap 7 and the sealing slips 2, and another part is scraped by oil scraping plate 6 attached to the lubricant oil on the axle, also flow in the above-mentioned space.These leakage of oils that compile are flowed back in the casing 1 by return tube 4.
