Abstract
The utility model relates to an improved planet carrier structure convenient for general utilization, comprising a planet carrier, a planet pinion shaft, two bearings, an inner retainer ring, an outer retainer ring, a planet gear and a retainer ring; wherein one side of the inner ring of one bearing is axially located by a planet pinion shaft step, and one side of the inner ring of the other bearing is axially located by the retainer ring, the retainer ring is sheathed on the planet pinion shaft and is stretched into a ring slot of the planet carrier; in the design, planet carrier bosses are replaced by the planet pinion shaft step and the retainer ring to axially locate the inner ring of the bearing, thereby leading the planet carrier to be in a no-boss structure; one blank can manufacture a plurality of the planet carriers that different transmission ratios correspond to different center distances, thereby not only reducing the mold quantity and blank kinds and being convenient for production, but also simplifying the processing to the planet carrier, not increasing the additional processing procedures and achieving the purpose of general utilization.
Description
Technical field
The utility model relates to a kind of planet wheel drive mechanism, especially a kind of improvement of being convenient to general planet carrier structure.
Background technique
Planet carrier plays key effect in the planet gear transmission, it not only plays transmitting torque, to play floating load balancing simultaneously, its basic structure as shown in Figure 1, by planet carrier (1), planet axis (2), two bearings (3), in, outer back-up ring (5) and planet wheel (4) are formed, two bearing inner races are made axially locating by the planet carrier boss, and planet carrier obtains blank by casting, necessary prefabricated boss on the blank, carry out the gold machining on boss plane then, the characteristics of this structure are that a centre distance is wanted corresponding mould, because mould can only cast out the planet carrier of same radial dimension boss.In the tandem product design, multiple velocity ratio is arranged usually with the one-level epicyclic transmission mechanism, the corresponding again different centre distance of different velocity ratios, what velocity ratios will be the result will have just need what moulds to cast planet carrier, so not only increase the cost of mould, but also increase trouble to production management, how to realize the requirement of the corresponding different centre distance planet carriers of same mould, reducing production costs, reduce the blank kind to reach and make things convenient for production management will be the problem that the utility model will be inquired into.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and proposes a kind ofly to realize that same mould can corresponding make the planet carrier that different centre distance require, to reach the mould generalization, to reduce production costs, reduce the improvement of being convenient to general planet carrier structure of blank kind and convenient management.
According to the foregoing invention purpose, the utility model is achieved through the following technical solutions.
A kind of improvement of being convenient to general planet carrier structure, it comprises planet carrier, planet axis, two bearings, inside and outside back-up ring and planet wheels, it is characterized in that described bearing inner race one side with planet axis step axially locating, another bearing inner race one side is by the spacer ring axially locating.
Described spacer ring is set on the planet axis, and stretch in the annular groove that inserts planet carrier the spacer ring outer end.
Compared with prior art, two bearing inner races of the utility model axially locating replace the planet carrier boss with planet axis step and spacer ring, make planet carrier become no boss structure, removed centre distance and lug boss position concerns one to one, as long as being arranged like this, a kind of blank just can make the planet carrier of different centre distance, therefore and processing is also very convenient, finishes in same operation again, has the number of molds of minimizing, is convenient to production management, does not increase manufacturing procedure and advantage such as easy to process in addition.
Description of drawings
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with above-mentioned accompanying drawing the utility model embodiment is elaborated again.
Be convenient to the improvement of general planet carrier structure, as shown in Figure 2, it comprises planet carrier 1, planet axis 2, two bearings 3, inside and outside back-up ring 5, planet wheel 4 and spacer rings 6.Planet carrier 1 is designed to not have boss structure, bearing 3 inner rings one side is made axially locating (X place) by planet axis 2 steps, another bearing 3 inner rings one side is made axially locating (Y place) by the spacer ring 6 that is set on the planet axis, so just can be according to needed centre distance processing planet axis hole and annular groove on planet carrier, realize that one pair of mould can generalization, cast out the requirement of the multiple planet carrier that is applicable to that the corresponding different centre distance of different drive ratios require, compare with Fig. 1 planet carrier, the utility model structure is simpler, more convenient casting, needn't increase manufacturing procedure in addition, reduce the blank kind, be convenient to production management.
Claims (2)
1, a kind of improvement of being convenient to general planet carrier structure, it comprises planet carrier (1), planet axis (2), two bearings (3), inside and outside back-up ring (5) and planet wheel (4), it is characterized in that a described bearing (3) inner ring one side with planet axis (2) step axially locating, another bearing (3) inner ring one side is by spacer ring (6) axially locating.
2, the improvement of being convenient to general planet carrier structure according to claim 1 is characterized in that described spacer ring (6) is set on the planet axis (2), and stretch in the annular groove that inserts planet carrier (1) the spacer ring outer end.
