Abstract
The utility model discloses a planet gear wrench. The planet gear wrench comprises a handle, a connecting sleeve, a gear sleeve, an upper planet frame, a lower planet frame and a planet gear group; the handle and the connecting sleeve are connected through a pin; the upper planet frame and the lower planet frame are installed inside the gear sleeve; the handle is fixedly connected to the gear sleeve external wall; a sun gear is installed on the lower planet frame; a central shaft of the sun gear forms into a power output shaft; three planet gears which are arranged on the periphery of the sun gear are installed on the upper planet frame; the top of the upper planet frame is connected with the connecting sleeve through a square shaft; the three planet gears and an inner gear of the gear sleeve and the sun gear are engaged. The planet gear wrench can solve the problems that the common wrench is inconvenient to operate and strenuous and the like and is suitable for multiple working environments due to the specific design structure.
Description
Technical field
The utility model belongs to field of tool, especially relates to a kind of planetary gear spanner.
Background technology
The spanner of selling in the market has normal activity spanner, socket wrench, and these spanners have certain working range, inconvenient operation and clumsiness.These spanners are all by staff, to act on the turning moment that produces on handle to realize the tightening of part on the other hand, need larger active force while wanting to tighten part, there is no the project organization of increasing action power, can not save muscle power.
Summary of the invention
The purpose of this utility model is to provide a kind of planetary gear spanner, and it can solve existing common wrench inconvenient operation, the problems such as effort, and special project organization can adapt to a lot of working environments simultaneously.
The technical solution adopted in the utility model is: a kind of planetary gear spanner, comprises handle, adapter sleeve, geared sleeve, upper planet frame, lower planet frame, planetary gear set; Planetary gear set comprises three planetary gears, described handle and described adapter sleeve link together by pin, said upper planet frame and lower planet frame are installed in geared sleeve, affixed a handles on geared sleeve outer wall, on lower planet frame, sun gear is installed, the central shaft of sun gear forms power output shaft, three planetary gears that sun gear around arranges are arranged on upper planet frame, the top of upper planet frame links together by a square shaft and said adapter sleeve, and three planetary gears are meshed with internal gear and the sun gear of described geared sleeve respectively.
When rotary handle, can drive adapter sleeve to rotate, thereby drive upper planet frame to rotate, three planetary gears of planetary gear set are connected with circular shaft with upper planet wheel carrier, thereby three planetary gears can rotate along with the rotation of upper planet frame, three planetary gears are meshed with sun gear, the rotation of planetary gear can drive the rotation of sun gear, and the below of sun gear is the work coupling part power output shaft of spanner, thereby realizes tightening or dismantling part with the rotation of sun gear.The utility model is reasonable in design, and structure is ingenious; Effectively reduced work firmly; Easy to operate quick.Special project organization can adapt to a lot of working environments simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model;
Fig. 2 is that master of the present utility model looks cross-sectional view;
Fig. 3 is local structure for amplifying schematic diagram of the present utility model.
The specific embodiment
A planetary gear spanner, as shown in Figure 1, Figure 2, Figure 3 shows, comprises handle 1, adapter sleeve 2, geared sleeve 3, upper planet frame 5, lower planet frame 4, planetary gear set; As shown in Figure 3, planetary gear set comprises three planetary gears 7,8,9.Described handle 1 links together by pin 10 with described adapter sleeve 2, and said upper planet frame 5 and lower planet frame 4 are installed in geared sleeve 3, affixed a handles 12 on geared sleeve 3 outer walls, and handle 12 one end have rubber sleeve 11.Sun gear 6 is installed on lower planet frame 4, the central shaft of sun gear 6 forms power output shaft, three planetary gears 7,8,9 that sun gear 6 around arranges are arranged on upper planet frame 5, the top of upper planet frame 5 links together by a square shaft and said adapter sleeve 2, and three planetary gears 7,8,9 are meshed with internal gear and the sun gear 6 of described geared sleeve 3 respectively.
