Abstract
The utility model discloses a kind of two grades of gear rings, the gear ring ontology of several external gear teeths is evenly equipped with including outer wall, the side of the inner wall of gear ring ontology is provided with annular mounting portion, several mounting holes are offered on annular mounting portion, its main feature is that: the other side of the inner wall of gear ring ontology, which is provided with, offers annular groove, several radial holes are evenly provided on gear ring ontology；The right edge of gear ring ontology is provided with several hole slots being uniformly distributed circumferentially, and is filled with shock-absorbing engineering plastics in hole slot.The annular groove and radial hole of the utility model setting cooperate, using the rotary centrifugal force of two grades of gear rings, can be transported to gear box oil is more as far as possible on external gear teeth, the wet face state in gear box oil when keeping external gear teeth long, conducive to the lubrication of two grades of gear rings, cleaning and heat dissipation, transmission effect is improved；When two grades of ring gear against rotation are vibrated, vibration energy can be absorbed by shock-absorbing engineering plastics, so that noise and vibration are reduced, it is highly beneficial to the service life for improving two grades of gear rings.
Description
Technical field
The utility model belongs to gear ring technical field, more particularly, to a kind of two grades of gear rings.
Background technique
Engine is the power take-off mechanism for loading locomotive, and loads locomotive and needed in the process of moving according to different roads
Condition changes the travel speed for loading locomotive, it is therefore desirable to which a kind of speed change gear coordinates the revolving speed of engine and the practical row of wheel
Sail speed.Speed changer be capable of fixing or stepping change output shaft and input shaft transmission ratio gear assembly, it is by driver
Structure and gear composition.Be cased with the gear ring of several different numbers of teeth, including two grades of gear rings on output shaft, two grades of gear rings usually because
It influences to be driven effect to there is the problems such as lubrication, weak heat-dissipating；Gear ring is in transmission process, due to many factors comprehensive function
As a result it can vibrate and generate noise.
Summary of the invention
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of two grades of gear rings.
The technical scheme adopted by the utility model is a kind of two grades of gear rings, are evenly equipped with several external gear teeths including outer wall
Gear ring ontology, the side of the inner wall of the gear ring ontology are provided with the annular mounting portion concentric with gear ring ontology, annular installation
Several mounting holes for fixed gear ring ontology are offered in portion, the other side of the inner wall of the gear ring ontology, which is provided with, to be offered
Annular groove, is evenly provided with several radial holes being connected to annular groove on the gear ring ontology, the outer end of radial hole and outer
The tooth socket of the gear teeth is opposite；The right edge of the gear ring ontology is provided with several hole slots being uniformly distributed circumferentially, and fills out in hole slot
Filled with shock-absorbing engineering plastics.
The mounting hole has 12, and circumferentially uniform is distributed on annular mounting portion.
The gear ring ontology and annular mounting portion integrally casting shaping.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model setting
Annular groove and radial hole cooperate, using the rotary centrifugal force of two grades of gear rings, can by gear box oil it is more as far as possible be transported to it is outer
On the gear teeth, the wet face state in gear box oil when keeping external gear teeth long mentions conducive to the lubrication of two grades of gear rings, cleaning and heat dissipation
Height transmission effect；When two grades of ring gear against rotation are vibrated, vibration energy can be absorbed by shock-absorbing engineering plastics, be made an uproar to reduce
Sound and vibration, it is highly beneficial to the service life for improving two grades of gear rings.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of A-A in Fig. 1.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 2: a kind of two grades of gear rings are evenly equipped with the gear ring sheet of several external gear teeths 1 including outer wall
Body 2, the side of the inner wall of the gear ring ontology 2 are provided with and the concentric annular mounting portion 3 of gear ring ontology 2, the gear ring
3 integrally casting shaping of ontology 2 and annular mounting portion, can be reduced production cost, and 12 are offered on annular mounting portion 3 for fixing
The mounting hole 4 of gear ring ontology 2, and circumferentially uniform be distributed on annular mounting portion 3；The inner wall of the gear ring ontology 2 it is another
Side, which is provided with, offers annular groove 5, several radial holes being connected to annular groove 5 are evenly provided on the gear ring ontology 2
6, the outer end of radial hole 6 is opposite with the tooth socket of external gear teeth 1, and annular groove 5 and radial hole 6 cooperate, using two grades of gear rings rotation from
Gear box oil being transported on external gear teeth when how long as far as possible as far as possible can be in gear box oil when keeping external gear teeth long by mental and physical efforts
Wet face state improve transmission effect conducive to the lubrication of two grades of gear rings, cleaning and heat dissipation；The right edge of the gear ring ontology 2 is set
Several hole slots 7 being uniformly distributed circumferentially are equipped with, MGB engineering plastics (attached drawing is not drawn into) are filled in hole slot, when two grades of teeth
When circle rotation is vibrated, vibration energy can be absorbed by shock-absorbing engineering plastics, so that noise and vibration are reduced, to two grades of raising
The service life of gear ring is highly beneficial.
