Abstract
The utility model relates to a caterpillar band walking speed reducer which comprises a main shaft. Two groups of planetary gear mechanisms are installed on the main shaft. A primary planetary gear mechanism is structurally characterized in that a primary sun gear is installed at one end of the main shaft, four primary planetary gears are arranged and meshed with the primary sun gear, the primary planetary gears are fixed on a primary planetary frame, and the primary planetary gears are meshed with annular gears. A secondary planetary gear mechanism is structurally characterized in that a secondary sun gear is installed on the main shaft, secondary planetary gears are arranged and meshed with the secondary sun gear, the secondary planetary gears are fixed on a secondary planetary frame, and the secondary planetary gears are meshed with the annular gears. The caterpillar band walking speed reducer is reasonable and compact in structure. Due to adoption of the primary planetary gears and the secondary planetary gears, the caterpillar band walking speed reducer is small in size, convenient to install, large in transmission ratio, capable of meeting heavy load operation of caterpillar band walking and long in service life.
Description
Technical field
The utility model relates to retarder, and is especially a kind of for the crawler travel retarder.
Background technique
At present, in existing engineering machinery, most crawler travel all adopts hydraulic driving, and oil hydraulic motor drives retarder driving driving wheel crawler travel is provided.The locomotor activity of crawler belt depends primarily on oil hydraulic motor and retarder.Reduction speed ratio is to consider whether to use the principal element of this retarder.The reduction speed ratio of retarder is large, and the moment of torsion of driving wheel is large, and due to the restriction of installation and usage space, retarder also should have smaller volume, and its using effect is needed that also enough reliabilities are arranged.
The retarder of available technology adopting is hard flank of tooth involute cylindrical gear retarder, its complex structure, and velocity ratio is little, and volume is large, and poor reliability easily breaks down, and can't be applied to track-type than the occasion of heavy load.
The model utility content
The applicant is for adopting the shortcomings such as hard flank of tooth involute cylindrical gear retarder poor reliability, velocity ratio is little, bearing capacity is little in above-mentioned existing production technology, another kind of crawler travel retarder is provided, thereby adopts two-stage epicyclic reduction, increase velocity ratio, compact structure, good reliability.
The technological scheme that the utility model adopts is as follows:
A kind of crawler travel retarder comprises main shaft, and two groups of planetary gears are installed on described main shaft,
The structure of primary planet pinion mechanism is: described main shaft one end is installed the one-level sun gear, with the engagement of one-level sun gear, four one-level planet wheels is installed, and described one-level planet wheel is fixed on primary planet carrier, described one-level planet wheel and ring gear engagement;
The structure of secondary planetary gear mechanism is: comprise the secondary solar gear that is installed on main shaft, with the secondary solar gear engagement, the secondary planet wheel is installed, described secondary planet wheel is fixed on the secondary planet frame, described secondary planet wheel and ring gear engagement.
As further improvement in the technical proposal:
Described primary planet carrier is installed on an end of secondary solar gear, described primary planet carrier and secondary solar gear engagement driving;
The facewidth of described secondary solar gear is greater than the facewidth of one-level sun gear;
The facewidth of described secondary planet wheel is greater than the facewidth of one-level planet wheel.
The beneficial effects of the utility model are as follows:
The utility model compactness rational in infrastructure adopts two-stage planet, and volume is little, and is easy for installation, and velocity ratio is large, can be satisfied with the work of track-type heavy load, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, main shaft; 2, secondary planet frame; 3, ring gear; 4, secondary planet wheel; 5, secondary solar gear; 6, primary planet carrier; 7, one-level planet wheel; 8, one-level sun gear.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the crawler travel retarder of the present embodiment comprises main shaft 1, and two groups of planetary gears are installed on main shaft 1,
The structure of primary planet pinion mechanism is: main shaft 1 one ends are installed one-level sun gear 8, with 8 engagements of one-level sun gear, four one-level planet wheels 7 are installed, and one-level planet wheel 7 is fixed on primary planet carrier 6, one-level planet wheel 7 and ring gear 3 engagements;
The structure of secondary planetary gear mechanism is: comprise the secondary solar gear 5 that is installed on main shaft 1, with secondary solar gear 5 engagements, secondary planet wheel 4 is installed, secondary planet wheel 4 is fixed on secondary planet frame 2, secondary planet wheel 4 and ring gear 3 engagements.
The facewidth of secondary solar gear 5 is convenient to the engagement of secondary solar gear 5 and primary planet carrier 6, and is gained in strength greater than the facewidth of one-level sun gear 8, increases reliability.
The facewidth of secondary planet wheel 4 has improved working strength and the functional reliability of secondary planet wheel 4 greater than the facewidth of one-level planet wheel 7.
in actual using process, at first one-level differential gear train action, the rotation of main shaft 1 is delivered to one-level sun gear 8, one-level sun gear 8 drives four one-level planet wheels, 7 revolution that are engaged with, this moment, one-level planet wheel 7 drive primary planet carriers 6 rotated, due to primary planet carrier 6 and secondary solar gear 5 engagement driving, thereby start the action of secondary planet train, primary planet carrier 6 drives secondary solar gear 5 and rotates, secondary solar gear 5 drives secondary planet wheel 4 and rotates, because secondary planet frame 2 is to be fixedly connected with, this moment, the secondary planet train became fixed shaft gear train, engagement driving occurs with ring gear 3 in secondary planet wheel 4 simultaneously, thereby produce the output of big speed ratio.
It is rational in infrastructure, compact, adopts double reduction, and velocity ratio is large, and bearing capacity is large, reliable operation.
Above description is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
