Abstract
The utility model relates to a hand-operated driving device, which comprises a housing, a poking gear, a gear shaft, a compression spring, a retainer ring and a spring seat. The poking gear is provided with a long shaft and then can drive the poking gear to rotate; the gear shaft penetrates the casing; the retainer ring is arranged at one end in the casing, which is far away from the poking gear;the spring seat is mounted on the retainer ring; and the compression spring has a certain pre-tightening force and is mounted between a clamping seat and the housing. The deice has the advantages of simple structure, convenient operation and working difficulty reduction, and can realize the rotating and barring of a gear of a speed reducer by dispensing with the disassembly of the speed reducer.
Description
Technical field
The utility model relates to a kind of hand crank transmission device.
Background technique
In the transmission of mechanical field, what generally adopt is gear reduction.And in the design of retarder, be that parts such as reduction gear are arranged in the casing mostly.When carrying out retarder repairing and regular maintenance, need elder generation to the gear rotation Moving plate car in the casing, carry out trouble analysis.And existing retarder can't be stirred the parts such as reduction gear of inside, necessary decomposition, analysis of failure earlier, and then install and debug, very inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of retarder that do not decompose and realizes jiggering, makes things convenient for the device of retarder repairing and regular maintenance.
Concrete technological scheme of the present utility model is that device comprises: housing, handsetting gear, gear shaft, pressure spring, collar, spring seat.Described handsetting gear has a major axis can drive the handsetting gear rotation, described gear shaft passes housing, end away from handsetting gear in housing is installed collar, and mounting spring seat on collar, pressure spring have certain pretightening force and be installed between deck and the housing.
This device is installed on the reduction case, and guarantee by the gear shaft pressure spring make handsetting gear have after certain displacement can with the gear engagement in the speed reducer, and gear shaft is not being applied under the situation of external force, handsetting gear and whole speed reducer break away from.
Description of drawings
Fig. 1 is the utility model schematic representation;
Fig. 2 is the work schematic representation of the utility model under engagement.
Embodiment
As shown in Figure 1, device comprises: housing 1, handsetting gear 3, gear shaft 6, pressure spring 2, collar 4, spring seat 5.Described handsetting gear 3 has a major axis 6 can drive handsetting gear 3 rotations, described gear shaft 6 passes housing 1, end away from handsetting gear 3 in housing 1 is installed collar 4, and mounting spring seat 5 on collar, pressure spring 2 have certain pretightening force and be installed between deck 5 and the housing 1.
This device is when the retarder proper functioning, and under the effect of pressure spring, handsetting gear and whole speed reducer break away from; And repairing or during regular maintenance, as shown in Figure 2, applying external force, make the gear engagement of handsetting gear and retarder by gear shaft, just can drive whole driving gear motion, the realization jiggering.This apparatus structure is simple, and is easy to operate, reduced work difficulty, can realize the rotation jiggering of reducer gear under the situation of speed reducer not being decomposed.Simultaneously, this hand crank transmission device adopts the cell cube design, and is easy to loading and unloading, simple in structure, and do not need to lubricate separately, easy to use and replacing.
