Abstract
The utility model provides a planet carrier capable of preventing a planet hinge pin from moving outwards. The planet carrier is formed by a planet hinge pin supporting frame, the planet hinge pin and a hinge pin fixing and connecting device. The planet hinge pin supporting frame comprises a left supporting plate, a right supporting plate and a supporting plate connecting block, through hinge pin holes are formed in the left supporting plate and the right supporting plate, the planet hinge pin is installed in the hinge pin holes, an elastic pin hole is formed in the end, connected with the left supporting plate, of the planet hinge pin, a supporting plate side hole leading to the elastic pin hole is formed in the outer side of the left supporting plate, the hinge pin fixing and connecting device comprises an elastic pin pad and an elastic pin, the elastic pin pad is installed in the elastic pin hole of the planet hinge pin, and the elastic pin penetrates through the supporting plate side hole to be connected with the elastic pin pad. The planet carrier can effectively prevent the planet hinge pin from moving outwards and has the advantages of being simple in structure, safe, reliable, small in size and convenient to detach.
Description
Technical field
The utility model relates to a kind of driving gear parts, relates in particular to a kind of planet carrier that prevents that planet bearing pin from scurrying out.
Background technique
At present, the practical problems such as the critical piece planet carrier in planetary type gear transmission unit generally adopts the modes such as welding, axle card, hole card, steel ball, pressing plate to prevent that planet bearing pin from axially scurrying out, and these modes all exist complex structure, it is large to take up room, manufacture difficulty, repair demolition is loaded down with trivial details.
Given this, be necessary to provide a kind of new planet carrier to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of planet carrier that prevents that planet bearing pin from scurrying out, and it is connected as a single entity planet carrier and planet bearing pin, can effectively prevent that planet bearing pin from axially scurrying out, have simple in structure, safe and reliable, volume is little, the advantage of convenient disassembly.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of planet carrier that prevents that planet bearing pin from scurrying out, it is characterized in that: by planet bearing pin supporting frame, be installed on planet bearing pin and bearing pin fixed connection apparatus composition on planet bearing pin supporting frame, described planet bearing pin supporting frame comprises left support plate, right support plate and be connected in a left side, dunnage contiguous block between right support plate, a described left side, right support plate is provided with the pin shaft hole of perforation, described planet bearing pin is installed in pin shaft hole, one end that planet bearing pin is connected with left support plate is provided with elasticity pin-and-hole, the outside of described left support plate is provided with that to lead to the dunnage of elasticity pin-and-hole lateral opening, described bearing pin fixed connection apparatus comprises resilient key pad and resilient key, described resilient key pad is installed in the elasticity pin-and-hole of planet bearing pin, described resilient key is connected with resilient key pad through dunnage is lateral opening.
Compared with prior art, a kind of planet carrier that prevents that planet bearing pin from scurrying out of the utility model utilizes resilient key and resilient key pad that planet bearing pin supporting frame and planet bearing pin are connected as a single entity, and planet bearing pin fixed effect is good, can effectively prevent that planet bearing pin from axially scurrying out.
Accompanying drawing explanation
Fig. 1 is a kind of cross-sectional view that prevents the planet carrier that planet bearing pin scurries out described in the utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the B portion enlarged view of Fig. 1.
Embodiment
Refer to shown in Fig. 1, the utility model provides a kind of planet carrier that prevents that planet bearing pin from scurrying out, by planet bearing pin supporting frame, be installed on planet bearing pin 1 and bearing pin fixed connection apparatus composition on planet bearing pin supporting frame, described planet bearing pin supporting frame comprises left support plate 2, right support plate 3 and be connected in a left side, dunnage contiguous block 4 between right support plate, a described left side, right support plate is provided with the pin shaft hole 5 of perforation, described planet bearing pin 1 is installed in pin shaft hole 5, one end that planet bearing pin is connected with left support plate is provided with elasticity pin-and-hole 6, the outside of described left support plate is provided with the dunnage lateral opening 7 of leading to elasticity pin-and-hole, described bearing pin fixed connection apparatus comprises resilient key pad 8 and resilient key 9, described resilient key pad 8 is installed in the elasticity pin-and-hole 6 of planet bearing pin, described resilient key 9 is connected with resilient key pad 8 through dunnage lateral opening 7.
The utility model in use, the dunnage contiguous block 4 that utilizes left support plate 2, right support plate 3 and be connected between left and right dunnage forms both arms supporting planet bearing pin shelf structure, utilize resilient key pad 8 and resilient key 9 that planet bearing pin supporting frame and planet bearing pin 1 are connected as a single entity, can effectively prevent that planet bearing pin from axially scurrying out, have simple in structure, safe and reliable, volume is little, the advantage of convenient disassembly.
The above; it is only most preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, any method content of utilizing above-mentioned announcement is made many possible variations and modification to technical solutions of the utility model, all belongs to the scope of claims protection.
