Abstract
The utility model discloses a poor shell and spiral bevel gear's mounting structure, integrative casting shaping is adopted in poor shell (1), is provided with sphere inner chamber (1a) at the middle part of poor shell (1), the two of poor shell (1) be provided with with the communicating halfshaft hole of sphere inner chamber (1a) (1b), it has the straight oil groove (1c) of longitudinal extension to distribute on halfshaft hole (1b) the inner wall, is provided with the planetary gear shaft hole (1d) of transversely lining up sphere inner chamber (1a) on poor shell (1), and the outer wall level of poor shell (1) is outwards extended and is formed spiral bevel gear setting circle (1e), spiral bevel gear (2) suit is close to the one side in planetary gear shaft hole (1d) outside poor shell (1) to through the fix with screw on spiral bevel gear setting circle (1e), the thickness H of spiral bevel gear (2) be greater than planetary gear shaft hole (1d) to spiral bevel gear setting circle (1e) apart from L. Have small, compact structure, convenient, the reliable characteristics of quality of manufacturing.
Description
Technical field
The utility model relates to a kind of differential art field, is specifically related to the mounting structure of difference shell and spiral bevel gear.
Background technique
Differential mechanism assembles by differing from shell, planetary pinion, differential gear and planet pin.Difference shell serves as planetary wheel carrier, and planetary pinion, differential gear and planet pin are arranged in poor shell.Inner chamber is provided with for holding planetary pinion and differential gear at the middle part of difference shell, two of difference shell is provided with half axis hole that communicates with inner chamber for installing semiaxis, difference shell is provided with the planetary gear shaft hole of lateral direction penetrating inner chamber for installing planet pin, and the outer wall of difference shell horizontally outward extends to form spiral bevel gear setting circle for installing fixing spiral bevel gear.
The subject matter that existing structure exists is: (1) inner chamber is curved surface, and holding space is little, and the overall dimensions of difference shell is higher; (2) for preventing planet pin from exiting planetary gear shaft hole, usually also need to wear spring bolt for fixing planet pin on difference shell; (3) half shaft hole inner walls are provided with helical oil groove, must be added by machine and form, add one technique.
Model utility content
Of the present utility modelly aim to provide a kind of mounting structure differing from shell and spiral bevel gear, have that volume is little, the feature of compact structure, easily manufactured, reliable in quality.
For this reason, the technological scheme that the utility model adopts is: a kind of mounting structure differing from shell and spiral bevel gear, described poor shell adopts integrally casting shaping, the middle part of difference shell is provided with sphere inner chamber, two of difference shell is provided with half axis hole communicated with sphere inner chamber, described half shaft hole inner wall is distributed with the straight oil groove of longitudinal extension, difference shell is provided with the planetary gear shaft hole of lateral direction penetrating sphere inner chamber, the outer wall of difference shell horizontally outward extends to form spiral bevel gear setting circle, described spiral bevel gear is sleeved on the outer side near planetary gear shaft hole of poor shell, and be fixed by screws on spiral bevel gear setting circle, the thickness H of described spiral bevel gear is greater than the distance L of planetary gear shaft hole to spiral bevel gear setting circle.
The beneficial effects of the utility model:
(1) sphere inner chamber can increase the volume of inner chamber, and the external frame of planetary pinion, differential gear mates with sphere inner chamber, reduces the whole height of difference shell, makes overall structure more compact;
(2) thickness limiting spiral bevel gear is greater than the distance of planetary gear shaft hole to spiral bevel gear setting circle, the two ends of planet pin are made to be against on the inwall of spiral bevel gear, prevent planet pin from moving axially by spiral bevel gear, not needing, spring bolt is set in addition and fixes;
(3) half shaft hole inner walls are provided with straight oil groove, are formed in casting process, eliminate one machining sequence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, a kind of mounting structure differing from shell and spiral bevel gear, difference shell 1 adopts integrally casting shaping, is provided with sphere inner chamber 1a for holding planetary pinion and differential gear at the middle part of difference shell 1.The half axis hole 1b that communicates with sphere inner chamber 1a is provided with for installing semiaxis at two of difference shell 1.Differential mechanism, to while the semiaxis transferring power of both sides, allows both sides semiaxis to rotate with different rotating speeds, meets two sidecar wheels and makes Unequal distance with the form of pure rolling as far as possible and travel, reduce the friction on tire and ground.
Half axis hole 1b inwall is distributed with the straight oil groove 1c of longitudinal extension, preferably, each half axis hole 1b inwall is evenly equipped with three straight oil groove 1c, but is not limited to three.
Difference shell 1 is provided with the planetary gear shaft hole 1d of lateral direction penetrating sphere inner chamber 1a for installing planet pin, and two planetary pinions are sleeved on planet pin relatively, and planetary pinion engages with differential gear.The outer wall of difference shell 1 horizontally outward extends to form spiral bevel gear setting circle 1e, and spiral bevel gear 2 is sleeved on the outer side near planetary gear shaft hole 1d of poor shell 1, and is fixed by screws on spiral bevel gear setting circle 1e.
The thickness H of spiral bevel gear 2 is greater than the distance L of planetary gear shaft hole 1d to spiral bevel gear setting circle 1e, makes the two ends of planet pin be against on the inwall of spiral bevel gear 2, exits to prevent planet pin in planetary gear shaft hole 1d.Spiral bevel gear 2 is with moment shell 1 to rotate together, and spiral bevel gear 2 is connected with the power input shaft of differential mechanism.
Claims (2)
1. one kind differs from the mounting structure of shell and spiral bevel gear, it is characterized in that: described poor shell (1) adopts integrally casting shaping, the middle part of difference shell (1) is provided with sphere inner chamber (1a), two of difference shell (1) is provided with half axis hole (1b) communicated with sphere inner chamber (1a), described half axis hole (1b) inwall is distributed with the straight oil groove (1c) of longitudinal extension, difference shell (1) is provided with the planetary gear shaft hole (1d) of lateral direction penetrating sphere inner chamber (1a), the outer wall of difference shell (1) horizontally outward extends to form spiral bevel gear setting circle (1e), described spiral bevel gear (2) is sleeved on poor shell (1) outward near the side of planetary gear shaft hole (1d), and be fixed by screws on spiral bevel gear setting circle (1e), the thickness H of described spiral bevel gear (2) is greater than the distance L of planetary gear shaft hole (1d) to spiral bevel gear setting circle (1e).
2. the mounting structure of poor shell according to claim 1 and spiral bevel gear, is characterized in that: each described half axis hole (1b) inwall is evenly equipped with three straight oil grooves (1c).
