Description

A kind of robot crossed roller bearing

Technical field

The utility model belongs to Production of bearing field, relates generally to a kind of robot crossed roller bearing.

Background technology

With the continuous progress of current mankind science and technology, robot industry becomes what is very discussed warmly by people in recent years Topic, either all there is the figure of robot in terms of construction industry, manufacturing industry, service trade are even with medical science.With people couple Robot requires to improve, and the thing followed is exactly the raising to the performance requirement of robot parts, and crossed roller bearing is exactly One of which.In the current technology, robot with crossed roller bearing in use, because plug and plug hole were Degree coordinates, and the grease of Bearing inner can overflow from plug hole under turning effort, cause the pollution of surrounding environment；In addition, taper pin It is tapered with taper pin-hole, it can only unidirectionally coordinate insertion, it is low to assemble up cumbersome efficiency.And if bearing parts is because of heat treatment change Shape and if producing rigging error the bearing assembly work in later stage will produce larger resistance, it is also possible to generation is done over again phenomenon.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is that a kind of robot crossed roller axle can be provided Hold.By improving sealing property, grease seepage is effectively prevent, not only reduces processing technology, reduces production cost, and significantly Reduce the assembly difficulty in later stage.

The utility model realizes that above-mentioned purpose adopts the technical scheme that：A kind of robot includes plug with crossed roller bearing Son, outer ring, spring catch, sealing ring, pin-and-hole, plug hole is provided with described outer ring, sealing-plug is installed in the plug hole Son, sealed step is provided with described plug, described sealing ring is fixedly connected in sealed step, in the outer ring and right Pin-and-hole is provided with the plug answered, described spring catch is plugged with the pin-and-hole.

Further, described sealed step is U-type groove structure.

Further, the sealing ring seals ring for the rice font of ring-type.

Further, the pin-and-hole is a cylindrical through hole.

Further, described spring catch is hollow cylindrical pin.

Further, described spring catch side has spring catch breach.

The utility model effectively prevent grease seepage, avoid kind of bearings and using by improving sealing property The oil leakage phenomenon occurred in journey, there are many conveniences for the use of product in itself and maintenance, reduce oil leakage phenomenon pair The service life of bearing in itself also has certain extension effect.The improvement of taper pin is substituted using spring catch, not only reduces and adds Work technique, reduces production cost, and the assembly work to the bearing later stage has been greatly reduced difficulty.

Brief description of the drawings

Fig. 1 is assembling structure schematic diagram of the present utility model.

In figure：1st, plug, 2, outer ring, 3, spring catch, 4, sealed step, 5, sealing ring, 6, pin-and-hole, 7, spring catch breach.

Embodiment

Below in conjunction with the accompanying drawings, the utility model is further illustrated by embodiment.

As shown in Figure 1：Robot described in the present embodiment crossed roller bearing include plug 1, outer ring 2, spring catch 3, Sealed step 4, sealing ring 5, pin-and-hole 6 and spring catch breach 7.Roller is assembled for bearing internal external circle is overall bearing Need to assemble by plug hole, in order to ensure the assembly precision of bearing to greatest extent, usually opened on the outer ring 2 of bearing There is plug hole, assembling completes later again installing stopper 1 and plug hole is sealed.The plug 1 is the plug that bearing generally uses Son.Sealed step 4 is provided with described plug 1, the sealed step 4 is close to the side of bearing outer ring internal diameter in plug 1 A U-type groove is processed, the U-type groove is sealed step 4, makes it be not easy to slide for fixed seal ring 5, offsets；The sealing Circle 5 is that the cross sectional shape of ring-type is the sealing ring of meter font, is sleeved in the sealed step of bearing plug, sealing ring 5 Prominent part and the hole wall and sealed step 4 of plug hole are brought into close contact, because the sealing ring 5 that section is rice font is one The structure of ring-type, therefore it can form the seepage that band reduces grease, due to having four on the rice font sealing ring 5 of ring-type Endless belt, plug hole and the rank of sealing station 4 are sealed so four sealing lines can be formed, this will greatly reduce oozing for grease Leakage.The pin-and-hole 6 of an axial direction is processed in the outer ring 2 and the bottom of the sealed step 4 of corresponding plug 1, the pin-and-hole 6 is one The through hole of cylinder, inserted with spring catch 3 in described pin-and-hole 6.Described spring catch 3 is hollow cylinder, in spring There are a breach, as spring catch breach 7, alternative original taper pin in the side of pin 3.Only need to be by spring catch when being installed In 3 insertion pin-and-holes 6, spring catch can be tightly pressed against by pin when acting on spring catch insertion pin-and-hole 6 due to spring catch breach 7 On hole wall, and without having to worry about caused error after heat treatment, while only need to be drilled just on the processing of pin-and-hole Can be so that the step that will ream directly dispenses, and saves processing cost, improves processing efficiency.
