Abstract
The utility model provides a single-stage double-speed ratio speed reducer, which can produce double-speed ratio on a single-stage speed reducer to make a driving mechanism realize two output speed under the condition of equal power. The speed reducer is characterized in that the output shaft and the input shaft of the utility model are assembled with two pairs of gears which are always engaged and are provided with different speed ratio, wherein, an upper gear is rigidly connected with the input shaft; a big gear is arranged on the output shaft by a rolling bearing; a jaw clutch and a gear shifting rocker are all connected with the output by spline.
Description
The utility model belongs to the geared machine field, is a kind of single-stage double speed ratio speed reducer specifically.
The retarder of single-stage driving (ZD type) has only a kind of speed ratio, and it only depends on a pair of gear engagement, and two kinds of speed ratios can not be provided.And the retarder of energy shift speed change reaching or above grade two is too huge and heavy, is not easy to general.The variable moderator system that has pays with manual switching institute meshed gears, and therefore, very difficult aligning slips into, owing to do not adopt electronic gearshift technology, can not realize remote-controlled operation.
The purpose of this utility model then is the problem at above-mentioned existence, and a kind of two kinds of speed ratios that produce on single reduction gear are provided, and makes driving mechanism realize the single-stage double speed ratio speed reducer of two kinds of output speeds under the constant power condition.
The utility model technical solution:
A kind of single-stage double speed ratio speed reducer, it is equipped with two pairs of engagement, that have different speed ratios all the time gears 3 and 4 altogether on output shaft 1 and input shaft 2, wherein cog and input shaft 2 is rigidly connected, gearwheel then utilizes rolling bearing to be contained on the output shaft 1, and jaw clutch 5 and gear shift fork 6 all utilize spline to be connected with output shaft 1.
The utility model advantage:
The utility model is the speed change gear of the highly versatile of a compact structure, utilizes this device can make the different speed of various mechanism's outputs, so the Applicable scope broadness.As be used in the auxiliary hook use that main hook can be become fast lifting on the hoist, thereby can cancel auxiliary hoisting mechanism.
Fig. 1 is the utility model schematic representation.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: on output shaft 1 and input shaft 2, be equipped with altogether two pairs all the time the engagement, gear 3 and 4 with different speed ratios, wherein small gear and input shaft 2 are rigidly connected, gearwheel then utilizes rolling bearing to be equipped with on the output shaft 1, by electronic gearshift, only make wherein a pair of gear transmission moment, at this moment, another is in the no load running state gear, therefore, can select any speed ratio as required for use, specifically, be that jaw clutch 5 utilizes waving of gear shift fork 6 to make with gearwheel wherein to be meshed, because jaw clutch 5 and gear shift fork 6 all utilize spline to be connected with output shaft 1, therefore, the gearwheel that is engaged just can transmitting torque.
Gear shift fork 6 is to realize wiggly by shift motor by the cam mechanism that is equipped with in worm-gear toothing transmission device and the retarder.Between jaw clutch 5 and the gear shift fork 6 spring that keep-ups pressure is housed also,, guarantees that jaw clutch 5 meshes smoothly, thereby finish the gearshift function by means of the slow-speed of revolution and the low moment of torsion of drive motor.
Claims (2)
1, a kind of single-stage double speed ratio speed reducer, it comprises input shaft, output shaft, gear, it is characterized in that on output shaft (1) and input shaft (2), being equipped with altogether two pairs of engagement, that have different speed ratios all the time gear (3) and (4), wherein cog and be rigidly connected with input shaft (2), gearwheel then utilizes rolling bearing to be contained on the output shaft (1), and jaw clutch (5) and gear shift fork 6 all utilize spline to be connected with output shaft (1).
2, single-stage double speed ratio speed reducer according to claim 1 is characterized in that between jaw clutch (5) and the gear shift fork (6) spring that keep-ups pressure being housed also.
