CN2654936Y - Spherical bearing with block shaft for lawn mowing machine - Google Patents

Abstract

The utility model relates to a structure technology for a lawn mower, comprising an upper bearing seat, a lower bearing seat, a bearing and a bearing bush; a concave groove, which is matched with wall thickness of the body, is arranged on the outer surface of the upper bearing seat; bolt connection is used between the upper bearing seat and the lower bearing seat. Because the concave groove is arranged on the upper bearing seat, the body can be partially inserted into the concave groove; the upper bearing seat and the body can be integrated through welding. The utility model has the advantages of strengthening the connection firmness between the upper bearing seat and the body, effectively avoiding the problem of being torn for former technology and guaranteeing normal using equipment.

Description

A lawn mower spherical bearing of usheing to seat

Technical field

The utility model relates to the structure technology of lawn mower.

Background technique

The lawn mower rolling bearing units are by bearing housing, bearing, and are arranged on the outer upper and lower bearing support of bearing and form, and the Placement of existing bearing and body is for directly to be connected upper and lower bearing support in the positioning hole of body by bolt.Because organism material is soft thin, and this position moisture-sensitive and corrosion.Comparatively speaking, the body strength deficiency, common attachment hole is torn, draws bad, and the equipment that influences uses.In addition, owing to be subjected to the restriction of position, mounting or dismounting inconvenience.

The model utility content

The lawn mower that it is good that the utility model purpose is to design an a kind of bearing and body connectivity spherical bearing of usheing to seat.

The utility model comprises upper bearing bracket, step, bearing, bearing housing, and the groove that setting of upper bearing bracket outer surface and body wall thickness are complementary connects with bolt between upper and lower bearing support.

Because the utility model is offered groove at upper bearing bracket, the body part can be plugged in this groove, by welding, upper bearing bracket and body are connected as a single entity, strengthened the connectivity robustness of upper bearing bracket and body, effectively avoid the generation of tearing phenomenon in the conventional art, thus the normal use of support equipment.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is that the A-A of Fig. 1 is to cut-away view.

Among the figure, 1 dustproof snare, 2 copper sheathings, 3 bodies, 4 nylon ball spherical bearings, spherical bearing block on 5,6 lower peripheral surface bearing supports, 7 bearing housings, 8,9 bolts, 10 grooves.

As shown in Figure 1, 2, at axle 8 peripheral hardware bearing housings 7, in bearing housing 7 peripheral hardware nylon ball spherical bearings 4,5,6 of upper and lower spherical bearing blocks connect with two groups of bolts 9, and nylon ball spherical bearing 4 is within it spacing.

Groove 10 is offered in two ends and centre at last spherical bearing 5, and the width of this groove 10 is slightly larger than the wall thickness of body 3.During installation bearing is arranged on a lower limb of body 3, this edge of body 3 is plugged in the groove 10 of spherical bearing block 5, and welding is fixing.

Claims (1)

1, a lawn mower spherical bearing of usheing to seat comprises upper bearing bracket, step, bearing, bearing housing, it is characterized in that the groove that setting of upper bearing bracket outer surface and body wall thickness are complementary, and connects with bolt between upper and lower bearing support.
