Abstract

The utility mode provides a reducer containing a bearing. The reducer comprises a supporting shell and an output flange shaft which stretches out from the shell. The reducer is characterized in that the bearing comprises an outer ring with a flange and an inner ring; the outer ring of the bearing is fixedly connected with the supporting shell through bolts, the output flange shaft is sleeved with the inner ring of the bearing, and an O-shaped sealing ring is arranged between the supporting shell and the outer ring and plays the radial sealing role; the outer ring of the bearing is in clearance fit with the shell of the reducer and is positioned through a bolt arranged on the right end of the bearing, and a framework oil seal can seal the end surface of the bearing. The reducer provided by the utility model has high carrying capacity, the assembly technology of the reducer is optimized, and the cost is reduced.

Description

A kind of speed reducer that contains bearing

Technical field

The utility model relates to a kind of speed reducer that contains bearing.

Background technique

Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is the supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.The problems such as normally used bearing is standard rolling bearing, but the bearing capacity deficiency occurs sometimes, and assembly technology is bad.

The model utility content

The purpose of this utility model is to solve current standard rolling bearing to have the bearing capacity deficiency, and the problem that assembly technology is bad, provide a kind of speed reducer that contains bearing.

For reaching above-mentioned purpose, the utility model provides a kind of speed reducer that contains bearing, comprise support housing and the output flange axle certainly stretched out in this housing, it is characterized in that: bearing comprises outer ring and the inner ring that flange is installed, the outer ring of bearing is fixedly connected with by screw with support housing, its inner ring is set on the output flange axle, is provided with the O RunddichtringO between support housing and outer ring and plays the radial seal effect; Be Spielpassung between bearing outer ring and decelerator shell, just by the screw of right-hand member, located the end face of skeleton oil seal bearing.

The utility model has the advantages that: improved the bearing capacity of bearing, optimized assembly technology, and reduced cost.

The accompanying drawing explanation

Below with reference to accompanying drawing, the utility model is described in further details:

Fig. 1 is the output end structure schematic diagram of the speed reducer that contains bearing;

Fig. 2 is the structural representation of bearing

In figure: 1, outer ring; 2, inner ring; 3, bearing; 4, support housing; 5, output flange axle; 6, screw; 7, O RunddichtringO; 8, outside framework oil seal; 9, flange.

Embodiment

There is the bearing capacity deficiency for solving current standard rolling bearing, the problem that assembly technology is bad, the present embodiment provides the bearing shown in a kind of Fig. 2, comprise outer ring 1, and on this outer ring 1, flange 9 being installed, thereby reaching the diameter that as far as possible strengthens bearing inner race 2 in limited space, is the reserved enough installing spaces of the design of practical application axis, optimize assembly technology, reduce costs.

Figure 1 shows that a kind of speed reducer that contains above-mentioned bearing, figure is not difficult to find out thus, the outer ring 1 of bearing 3 is fixedly connected with by screw 6 with support housing 4, and its inner ring 2 is set on output flange axle 5, by this bearing 3, reached the diameter that as far as possible strengthens bearing inner race 2 in limited space, for the reserved enough installing spaces of the design of output flange axle 5, improve the bearing capacity of bearing simultaneously, on the assembly technology of bearing, realize optimizing, reduce costs, realize the Economy of producing.

Be not difficult to find out by Fig. 1, be provided with O RunddichtringO 7 between support housing 4 and outer ring 1 and play the radial seal effect.Between bearing outer ring 1 and decelerator shell, it is Spielpassung, just by the screw of right-hand member, located, O RunddichtringO 7 can prevent the oil leak of speed reducer inside. the end face of outside framework oil seal 8 stuffing box bearings, prevent that speed reducer lubricant oil from leaking by bearing face, outside framework oil seal 8 can also prevent that extraneous air, dust, abrasive particle etc. from entering bearing and speed reducer, guaranteed the normal operation of speed reducer all parts simultaneously.

More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.

Claims

1. a speed reducer that contains bearing, comprise support housing and the output flange axle certainly stretched out in this housing, it is characterized in that: bearing comprises outer ring and the inner ring that flange is installed, the outer ring (1) of bearing (3) is fixedly connected with by screw (6) with support housing (4), it is upper that its inner ring (2) is set in output flange axle (5), is provided with O RunddichtringO (7) between support housing (4) and outer ring (1) and plays the radial seal effect; Be Spielpassung between bearing outer ring (1) and decelerator shell, just located by the screw of right-hand member, the end face of outside framework oil seal (8) stuffing box bearing.
