Abstract
The utility model discloses a pin shaft motion stopping mechanism of an excavator. The pin shaft motion stopping mechanism comprises a motion stopping plate, a pin shaft, a supporting seat, a shaft and a clamping spring, and is characterized in that when the pin shaft motion stopping mechanism is mounted, the shaft passes through the middle of the motion stopping plate and is fixed on a shaft shoulder; the clamping spring strides over a stopping groove of the motion stopping plate; and the two ends of the clamping spring are clamped into mounting holes of the supporting seat. The disassembly and assembly efficiency is high, and a pin shaft motion stopping manner that no wrench is needed is adopted; and the clamping spring for stopping the pin shaft is a ring-shaped spring steel wire, and the motion stopping groove is formed on the pin shaft motion stopping plate. The pin shaft motion stopping mechanism has a simple structure, is easy to manufacture, and is convenient to mount and use.
Description
Technical field
The utility model relates to a kind of excavator bearing pin stop mechanism.
Background technique
General excavator bearing pin means of retention mainly is through using stay bolt to pass bearing pin stop cover pin-and-hole and bearing pin pin-and-hole, forcing tightly with double nut at the bolt the other end then, in case screw bolt and nut comes off; Another kind of structure is normally connected by the bearing pin of band stop ear, is connected through bolt by two nut block and a block pressur plate and accomplishes spacing to bearing pin, and these two kinds of means of retention dismounting efficient are not high.
Summary of the invention
The utility model problem to be solved is, provides a kind of and strides across the locking groove of check plate with jump ring, and its two ends snaps in bearing both sides mounting hole, replaces stay bolt and double nut to fix the bearing pin of excavator with a jump ring.The excavator bearing pin stop mechanism that dismounting efficient is high, need not spanner.
The technical solution of the utility model is such: a kind of excavator bearing pin stop mechanism, comprise jump ring, bearing pin and bearing, and it is characterized in that jump ring is installed in the locking groove of bearing pin, its two ends is entrapped in the mounting hole on the bearing, and check plate is installed above the axle.Jump ring is the annular spring steel wire that two ends is not sealed.
Check plate and axle are arranged on the bearing pin, be designed with the locking groove that cooperates with jump ring on the check plate.Bearing two outer side surfaces are designed with the mounting hole that jump ring is installed.
Adopt the bearing pin stop mechanism advantage of technique scheme to be, very convenient, fast when disassembling and assembling pin shaft.Be designed with locking groove on the employed bearing pin otic placode of the utility model, be designed with mounting hole on the bearing, simple in structure, easily manufactured, with low cost, effect is obvious.
Description of drawings
It is such that the structure of the utility model constitutes:
Fig. 1 is that the overall structure of the utility model is installed the main schematic representation of looking of assembling.
Fig. 2 is the left view of Fig. 1 of the utility model.
Fig. 3 is the plan view of Fig. 1 of the utility model.

Fig. 5 is the plan view of part 2 bearing pins among Fig. 1 of the utility model.
Fig. 6 is the plan view of part 1 jump ring among Fig. 1 of the utility model.
Among Fig. 1～Fig. 6, jump ring (1), bearing pin (2), bearing (3), check plate (4), axle (5), locking groove (6), mounting hole (7).
Embodiment
The most preferred embodiment of the utility model is such, with reference to Fig. 1～Fig. 6, replaces stay bolt and double nut or pressing plate and bolt to fix the excavator bearing pin with the jump ring of an easy accessibility.This jump ring adopts suitable spring steel bar brake forming, and two terminations of jump ring are installed in respectively on the mounting hole on the bearing, jump ring wherein one section be assembled together with the bearing pin that is designed with locking groove, the elastic force through jump ring prevents bearing pin rotation and play.Referring to Fig. 1, Fig. 2, Fig. 3, jump ring (1) two ends is passed the mounting hole on the bearing (3) respectively, and jump ring (1) is stuck in the locking groove of bearing pin (2), and is simple in structure, and mounting or dismounting are convenient.Referring to Fig. 2, be designed with two mounting holes (7) on the bearing (3).Referring to Fig. 4, Fig. 5, bearing pin (2) is made up of check plate (4) and axle (5), and check plate is designed with locking groove on (4).Referring to Fig. 6, jump ring (1) is the annular spring steel wire that a two ends is not sealed.During installation, pore volume axle (5) passes and fixes in the middle of the check plate (4).Jump ring (1) strides across the mounting hole (7) that check plate (4) back its two ends of locking groove (6) snaps in bearing (3).
Claims (4)
1. an excavator bearing pin stop mechanism comprises jump ring, bearing pin and bearing, it is characterized in that jump ring (1) is installed in the locking groove (6) of bearing pin (2), and its two ends is entrapped in the mounting hole (7) on the bearing (3), and check plate (4) is installed above the axle (5).
2. according to the described a kind of excavator bearing pin stop mechanism of claim 1, it is characterized in that jump ring (1) is the annular spring steel wire that two ends is not sealed.
3. according to the described a kind of excavator bearing pin stop mechanism of claim 1, it is characterized in that having on the bearing pin (2) check plate (4) and axle (5), be designed with the locking groove (6) that cooperates with jump ring (1) on the check plate (4).
4. according to the described a kind of excavator bearing pin stop mechanism of claim 1, it is characterized in that bearing (3) two outer side surfaces are designed with the mounting hole (6) that jump ring (1) is installed.
