Abstract

The utility model discloses a bearing support assembly comprising a belt wheel shaft, two bearings and two retainer rings, wherein the belt wheel shaft is provided with two independent annular grooves, the two bearings are connected on the belt wheel shaft in a sleeved way and arranged between the two annular grooves, and the two retainer rings are independently connected on the two annular grooves in a clamped way. The bearing support assembly has the characteristic of further comprising a bearing support of a reinforced nylon material, wherein a bearing holding cavity of the bearing support is internally provided with two independent flaring troughs, the two bearings are independently fixed in the two flaring troughs, the waist of the outer fringe of the bearing support is provided with an integrated lug boss, and the end faces of the lug boss, which are same with the driving end of the belt wheel shaft in direction, are provided with reinforcing ribs. According to the bearing support assembly provided by the utility model, the cost is reduced without reducing the strength of the structure of the bearing support, so that the normal work of the bearing support assembly is ensured.

Description

Bearing block assembly

Technical field

The utility model relates to a kind of elevator parts, particularly a kind of bearing block assembly.

Background technique

Existing bearing block assembly, its bearing support generally is cast iron quality, the cast iron price general charged is higher, cost is increased a lot, if but change other comparatively cheap materials into, then probably allow the intensity on the bearing block structure decrease, affect the normal use of bearing block assembly.

The model utility content

The purpose of this utility model is to provide a kind of cost the low bearing block assembly that can guarantee some strength in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the bearing block assembly that the utility model is designed, comprise a belt shaft, two bearings and two back-up rings, described belt shaft is provided with two independently annular grooves, two bearing housings are connected on the belt shaft, and between two annular grooves, two back-up ring stand-alone cards are connected on two annular grooves, it is characterized in that also comprising the bearing support that strengthens nylon material, be provided with two independently enlarging grooves in the accommodating cavity of the bearing of bearing support, two bearings independently are fixed in two enlarging grooves, and the waist of described bearing support outer is provided with the boss of integral type, are provided with stiffening rib between boss and the equidirectional end face of belt shaft driving end.

The bearing block assembly that the utility model obtains, replaced the bearing support of original cast iron quality with the bearing support that strengthens nylon material, greatly reduce the cost of enterprise, the setting of stiffening rib has guaranteed again the intensity on the bearing block structure, can not affect the normal use of bearing block assembly.

Fig. 3 is the bearing support generalized section of A-A among Fig. 1;

Fig. 4 is the schematic diagram of belt shaft among Fig. 1.

Among the figure: belt shaft 1, bearing 2, back-up ring 3, bearing support 4, stiffening rib 5, enlarging groove 6, annular groove 7, boss 8.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment:

Such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the bearing block assembly that the present embodiment provides, comprise a belt shaft 1, two bearings 2, two back-up rings 3 and strengthen the bearing support 4 of nylon material, described belt shaft 1 is provided with two independently annular grooves 7, two bearings 2 are socketed on the belt shaft 1, and between two annular grooves 7, two back-up ring 3 stand-alone cards are connected on two annular grooves 7, be provided with two independently enlarging grooves 6 in the accommodating cavity of the bearing of bearing support 4, two bearings 2 independently are fixed in two enlarging grooves 6, the waist of described bearing support 4 outers is provided with the boss 8 of integral type, is provided with stiffening rib 5 between boss 8 and the equidirectional end face of belt shaft 1 driving end.

In the specific implementation, first a bearing 2 is fixed in the mould of bearing support 4, and this bearing is to be placed on the position in the enlarging groove 6 of bearing support 4 bottoms and to carry out injection moulding, again another one bearing 2 is placed on the position in the enlarging groove 6 of bearing support 4 front portions behind bearing support 4 injection moldeds, then belt shaft 1 is inserted in the endoporus of bearing 2, and two annular grooves 7 on the belt shaft 1 lay respectively at the outside of two bearings 2, block the outside that 3, two back-up rings 3 of two back-up rings lay respectively at two bearings 2 in last two annular grooves 7 on belt shaft 1.

The bearing block assembly that the present embodiment obtains, replaced original cast iron quality with the bearing support 4 that strengthens nylon material, cost has reduced comparatively speaking, but the intensity that strengthens nylon is high less than cast iron, the design of stiffening rib 5 has remedied this defective, has guaranteed that the structure of bearing support 4 reaches certain intensity.
