Abstract
The utility model discloses a pendulum rod bearing axial fixing structure which comprises a support and a pendulum rod bearing which is placed on a gear shift device. A gear shift device positioning seat is placed on the support, and a positioning bearing is arranged on one side of the pendulum rod bearing, where the one side of the pendulum rod bearing is close to the gear shift device positioning seat. An inner ring of the pendulum rod bearing and an inner ring of the positioning bearing are connected into a whole. A positioning plate is arranged on the positioning bearing and is fixedly connected with the gear shift device positioning seat. The pendulum rod bearing axial fixing structure has the advantages of being simple in structure, reliable in connection, low in noise, energy-saving and long in service life.
Description
Technical field
The utility model relates to a kind of mechanical connecting structure, and more particularly, the utility model relates to a kind of axial fixing structure for the electric hammer Oscillating lever bearing.
Background technology
For save, convenient, electric hammer need to be with hammer, bore, not only hammer but also the function of boring roll into one, for this purpose, electric hammer arranges the gearshift that is arranged in parallel with transmission device at transmission mechanism and comes handoff functionality.The method that Oscillating lever bearing fixed form on the gearshift is commonly used at present is transmission device positioning seat clamping one " U " the shape press part by support, two pin of press part extend to the location bearing outer ring away from a side of gearshift positioning seat, and being pressed on tightly on this side, thereby the axial restraint of realization gearshift.Although this fixed form is simple, but because two pin of press part extend long, its butt power is limited, be not enough to overcome the axial float that Oscillating lever bearing produces under the state of hammer, not only because of the unhelpful consumed energy of vibration meeting, and can cause the electric hammer noise larger, and two pin of press part shorten its service life because fatigue fracture often appears in long-time vibration.
The utility model content
The purpose of this utility model is to overcome defects, and a kind of simple in structure, Oscillating lever bearing axial fixing structure of connecting reliable, low noise, energy-conservation, long service life is provided.
The utility model solves the in-problem technical scheme of prior art: a kind of Oscillating lever bearing axial fixing structure, comprise the Oscillating lever bearing on support, the gearshift, support is provided with the gearshift positioning seat, Oscillating lever bearing is provided with location bearing in the side near this positioning seat, the inner ring of Oscillating lever bearing and the inner ring of location bearing are connected as a single entity, described location bearing is provided with location-plate, is fixedly connected with between location-plate and the gearshift positioning seat.Because location-plate directly is set on location bearing, location bearing is fixedly connected with by between location-plate and the gearshift positioning seat, can learn according to mechanics principle, coupling torque is shorter like this, so that the power that is fixedly connected with makes it can not produce axial float greater than the axial float power that Oscillating lever bearing produces under the state of hammer, thereby avoid the generation of noise, for no reason consumed energy is conducive to energy-conservation and the physical and mental health operating personnel, greatly prolongs its service life.
Preferably, described location-plate is formed by the otic placode that the outer ring of location bearing extends outward.Be conducive to the realization that short moment form is fixedly connected with.
Preferably, described gearshift positioning seat outer peripheral face is provided with the projection that matches with otic placode.Be conducive to the realization that short moment form is fixedly connected with.
Preferably, described projection is provided with screwed hole at the end towards otic placode, and described otic placode is provided with the through hole that matches with screwed hole.Be threaded is to realize the plain mode that reliably is fixedly connected with.
The beneficial effects of the utility model are: simple in structure, connect reliable, low noise, energy-conservation, long service life.

The specific embodiment
Below by specific embodiment, and in conjunction with Figure of description the technical solution of the utility model is further described in detail:
Embodiment: a kind of Oscillating lever bearing axial fixing structure such as Fig. 1, shown in Figure 2, comprise support 1, Oscillating lever bearing 4 on the gearshift 3, be respectively equipped with gearshift positioning seat 11 and transmission device positioning seat 12 on the support 1, be connected with transmission device 2 on the transmission device positioning seat 12, gearshift 3 is arranged in parallel with transmission device 2, Oscillating lever bearing 4 is provided with location bearing 41 in the side near gearshift positioning seat 11, the inner ring of the inner ring of Oscillating lever bearing 4 and location bearing 41 is connected as a single entity, location-plate 411 is stretched out near an epitaxial lateral overgrowth of Oscillating lever bearing 4 in the outer ring of location bearing 41, location-plate 411 extends outward into three otic placodes 412 that isosceles triangle is arranged, arrange and three projections 111 that otic placode 412 positions match on the gearshift positioning seat 11, projection 111 is provided with screwed hole at the end towards otic placode 412, described otic placode 412 is provided with the through hole 413 that matches with screwed hole, and otic placode 412 is connected by screw thread with protruding 111.
Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
The content that is not described in detail in this specification belongs to the known prior art of those skilled in the art.
