Abstract

The utility model relates to a machinery gearing device, particularly an oil leakage preventing structure of the machinery gearing device. The machinery gearing device comprises an input and an output members and a wheel train which transmits torque between the input and the output members and makes the input and the output members generate rotary speed difference. The upper part of a box body has a passage which conveys lubricating oil to moving members. For avoiding oil leak caused by that intensely-splashed stream scours the oil seal or gaps occur on a sealing surface, an oil baffle disc for preventing oil leak is arranged on the output member. The oil baffle disc is covered on the circumference walls of a bearing and an oil storing room.

Description

Mchinery gearing device

The utility model relates to the leak-proof arrangement of a kind of mechanical transmission, particularly mechanical transmission.

The existing mechanical transmission device comprises: input, output link and between two members transmitting torque and make its train that produces speed discrepancy, the top of casing has passage from lubricant oil to moving link that carry.In order to prevent leakage of oil, generally on input, output link, oil sealing is housed.But spatter oily stream and wash away oil sealing, or because bearing, oil sealing wearing and tearing and when the gap occurring on sealing surface, leakage of oil is just unavoidable if having to swash.

For this reason, the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of mechanical transmission is provided, and it not only can be avoided swashing and spatters oily stream and wash away oil sealing, even and the gap appears on the sealing surface, also can stop oil leak effectively.

The technological scheme that realizes the utility model purpose is: a kind of mechanical transmission, comprise: input, output link and transmitting torque and make it produce the train of speed discrepancy between two members, the top of casing has passage from lubricant oil to moving link that carry, its difference is: output link is provided with the oil baffle disc that prevents leakage of oil, and this oil baffle disc covers on bearing and the reservoir compartment's perisporium.

And described train can be an epicyclic gear train.

And described train can be a fixed shaft gear train.

And described train can be a compound gear train.

And, can be provided with passage from lubricating grease to bearing that carry on the casing.

Because and the oil baffle disc that output link rotates together covers on bearing and the reservoir compartment's perisporium, so, get rid of under the effect in the covering of oil baffle disc with to the centrifugal throwing of lubricant oil, make lubricant oil can not be near bearing, be positioned at thereafter oil sealing and sealing surface, thereby avoided the leakage of lubricant oil.Covered bearing is then in addition by grease lubrication.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the sectional view of signal the utility model structure.

Fig. 2 is the left view of Fig. 1.

With reference to Fig. 1, Fig. 2, the utility model is a kind of mechanical transmission, for example, retarder or speed increaser, especially be subtracting of vertical setting, speed increaser, it comprises input, output link 1,19 and between two members transmitting torque and make it produce the train of speed discrepancy, the top of casing 10 has passage 2 from lubricant oil to moving link that carry, 5, as: hole or transport pipe, generally reservoir compartment 16 can be located at the bottom of casing 10, in order to increase the store oil amount, can also outside complete machine, establish a fuel tank 22 that communicates with reservoir compartment 16 in addition, its lubricating system can adopt pump 24 lubricant oil to be transported to the passage 2 on casing 10 tops, 5, lubricant oil is through this

passage

2,5 flow in the casing 10, and train is lubricated.

Spatter oily stream and wash away oil sealing 18 for fear of swashing, or to cause leakage of oil because of the gap occurring on the sealing surface (surface of contact between oil sealing 18 and the output link 19).Be provided with the oil baffle disc 14 that prevents leakage of oil on output link 19, this oil baffle disc 14 covers on bearing 17 and reservoir compartment's 16 perisporiums 15.Oil baffle disc 14 can the stationary fit mode be connected with output link 19, also can adopt screw or pin to connect, can be with output link 19 rotations to guarantee oil baffle disc 14.

For covered bearing 17 is lubricated, can be provided with passage 23 from lubricating grease to this bearing 17 that carry on the casing 10.

Technological points of the present utility model is applicable to mechanical transmission, especially vertical transmission device.Obviously, the related train of each embodiment can be: epicyclic gear train, fixed shaft gear train or compound gear train, for example: the compound gear train that the gear transmission of planetary pinion transmission, fixed shaft gear train or the two have concurrently simultaneously.Because these all belong to known prior art (rolling up the 32nd piece " gear transmission " referring to " mechanical engineering manual " the 6th that China Machine Press publishes September nineteen eighty-two).In fact, the accompanying drawing illustrated embodiment is the transmission device that has fixed shaft gear train and epicyclic gear train simultaneously.For example, its fixed shaft gear train can comprise a pair of intermeshing bevel gear 3,4.Its epicyclic gear train can comprise

central gear

8,13, ring gear 7,12 and the planet wheel 6,11 that also is meshed with it simultaneously between the two,

planet carrier

20,21 is evenly distributed on the circumference between

central gear

13,8 and the ring gear 12,7 planet wheel 11,6, described output link 19 can be an output shaft, also can be exactly planet carrier 20 shown in Figure 1.If consider in the problem of all carrying that is subjected under the force unbalance condition, then can pass through

central gear

8,13, ring gear 7,12 or planet carrier 21,19 float (or wherein any two float) solved, for example, realize that by profile of tooth joiner 9 central gear 13 floats, scheme can be consulted aforementioned " mechanical engineering manual " more specifically.
