Abstract
A kind of RV retarder bent axle supports special-purpose thin-wall bearing, relate to Production of bearing technical field, comprise bearing inner race (1), rolling element (2) and retainer (3), the raceway of described bearing inner race (1) is provided with track convex degree (c), the cylndrical surface of described rolling element (2) is provided with profiled rollers (a), the both sides of described bearing inner race (1) are respectively arranged with the retainer rib (b) of the raceway that upwards exceeds bearing inner race (1), and retainer (3) is set to M type band fore shaft; The utlity model has good service behaviour, can meet industrial robot precision, compact structure, long-life requirement.
Description
technical field:
The utility model relates to Production of bearing technical field, relates in particular to a kind of RV retarder bent axle and supports special-purpose thin-wall bearing.
background technique:
Industrial robot RV retarder bent axle supports special bearing must be shock-resistant, and the life-span is long, simultaneously in order to meet the requirement of industrial robot structure compactness, must adopt ultra-thin super narrow bearing.The ultra-thin super narrow bearing using at present generally adopts cylindrical roller retainer assembly, and the inner ring raceway of this bearing is retarder bent axle surface, processes very difficult; On a bent axle, have two or three such bearings of series connection, bearing is at Crankshaft to moving freely, and often phase mutual friction between retainer, reduces bearing life, affects smooth rotation; The easy stress in roller end is concentrated, and reduces working life.
summary of the invention:
In order to overcome the deficiency of background technique, the utility model provides a kind of RV retarder bent axle to support special-purpose thin-wall bearing, has good service behaviour, can meet industrial robot precision, compact structure, long-life requirement.
The utility model is to adopt following technological scheme to solve:
RV retarder bent axle supports a special-purpose thin-wall bearing, comprises bearing inner race, rolling element and retainer, and the raceway of described bearing inner race is provided with track convex degree, and the cylndrical surface of described rolling element is provided with profiled rollers.
Described RV retarder bent axle supports special-purpose thin-wall bearing, and the both sides of described bearing inner race are respectively arranged with the retainer rib of the raceway that upwards exceeds bearing inner race.
Described RV retarder bent axle supports special-purpose thin-wall bearing, and retainer is set to M type band fore shaft.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
The designed described RV retarder bent axle of the utility model supports special-purpose thin-wall bearing, has reduced difficulty of processing; Bearing inner race is provided with the raceway of convexity, and rolling element is provided with convexity, has increased bearing life and rotating speed; Bearing inner race arranges ultra-thin pair of rib, has avoided the friction of retainer; Retainer, with fore shaft, can make rolling element, retainer, inner ring become a whole assembly, is convenient to install; There is good service behaviour, can meet industrial robot precision, compact structure, long-life requirement.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, bearing inner race; 2, rolling element; 3, retainer; A, profiled rollers; B, retainer rib; C, track convex degree.
embodiment:
RV retarder bent axle as shown in Figure 1 supports special-purpose thin-wall bearing, comprise bearing inner race 1, rolling element 2 and retainer 3, the raceway of described bearing inner race 1 is provided with track convex degree c, the cylndrical surface of described rolling element 2 is provided with profiled rollers a, avoid the stress that rolling element 2 ends contact with the raceway of bearing inner race 1 to concentrate, improved bearing capacity; Bearing inner race 1 is easy to processing, avoids machining crankshafts surface to do roller surface, has reduced retarder difficulty of processing; The both sides of described bearing inner race 1 are respectively arranged with the retainer rib b of the raceway that upwards exceeds bearing inner race 1, described retainer rib b is set to superthin structure, can guide rolling element 2 to turn round in the raceway of bearing inner race 1, have avoided the friction of 3 of retainers; Bearing inner race 1 and bent axle drive fit, bearing inner race 1 thickness is very little, and one side raceway wall thickness 1.5mm because rolling element 2 and raceway are all with convexity, can increase bearing capacity simultaneously, can adopt less rolling element 2, guarantees the compact structure of bearing; Retainer 3 is set to M type band fore shaft, and rolling element 2 can rotate freely and not come off in retainer 3 pocket holes, makes retainer 3, rolling element 2, bearing inner race 1 become a complete assembly, is convenient to install.Bearing inner race 1 quenches through surface high frequency, and surperficial hard-core portion is soft, has good impact resistance.
The utility model does not describe part in detail for prior art.
The embodiment who selects in this article for open the purpose of this utility model, current think suitable, but will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment within the scope of this design and the utility model.
Claims (3)
