Abstract
The utility model discloses an elevator brake structure which comprises a brake, a transmission shaft and an encoder. A transmission shaft sleeve is arranged at the center of the brake, one end of the transmission shaft is provided with a transmission portion driving the brake, the transmission portion is located in the transmission shaft sleeve, the end face of the transmission portion of the transmission shaft is provided with a locking clamp groove, and the end portion of the encoder is provided with a connecting column in clamping connection with the locking clamp groove. An encoder connector and an encoder seat are omitted, and the material cost and the manufacture cost are reduced. The using quality of the encoder is improved, and the situation that the encoder is damaged in the installing process is decreased. Assembling errors are decreased, the connecting strength is enhanced, and the connection of the encoder is form. An encoder installing space is saved.
Description
Technical field
The utility model relates to the elevator traction machine technical field, particularly relates to a kind of elevator brake structure.
Background technology
Traditional elevator brake structure, coder are to be connected on the transmission shaft and by the coder seat by the coder connector to fix.The drawback of this kind structure is: erection procedure is loaded down with trivial details, fragile coder in the installation process, and this kind structure easily to cause coder to connect not firm, thereby cause rocking big, to debugging and use and produce a very large impact.
The utility model content
Based on this, at the problems referred to above, the utility model proposes a kind of novel elevator brake structure, can solve problems such as coder installation steps in installation process are loaded down with trivial details, fragile, connection is not firm and rock, save the use of coder connector and coder seat simultaneously, thereby save cost.
The technical solution of the utility model is: a kind of elevator brake structure, comprise drg, transmission shaft and coder, the center of described drg has drive shaft sleeve, one end of described transmission shaft has the driving section that drives drg, this driving section is positioned at described drive shaft sleeve, the driving section end face of described transmission shaft is provided with the locking draw-in groove, and the end of described coder is provided with and the joint pin of locking the draw-in groove clamping.
In a preferred embodiment, the cross-sectional plane of the driving section of described transmission shaft is gear-like.Purpose is to guarantee that transmission shaft can drive drg well.
In a preferred embodiment, the cross-sectional plane of described joint pin and described locking draw-in groove is the regular hexagon that size is complementary.Purpose is to guarantee that coder can be fixed on the driving section of transmission shaft well.
The beneficial effects of the utility model are:
1, saves the use of coder connector and coder seat, reduced material cost and manufacturing cost;
2, improve the service property (quality) of coder, reduced the damaged condition of coder in installation process;
3, reduced assembly error, strengthened linking intensity, it is more firm that coder is connected;
4, saved the installing space of coder.
Description of drawings
Fig. 1 is the scheme drawing of the described elevator brake structure of the utility model embodiment;
Description of reference numerals:
The 10-drg, 20-transmission shaft, 30-coder, 40-drive shaft sleeve, 50-joint pin.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Embodiment:
As shown in Figure 1, a kind of elevator brake structure comprises drg 10, transmission shaft 20 and coder 30.The center of described drg 10 has drive shaft sleeve 40, and an end of described transmission shaft 20 has the driving section that drives drg 10, and this driving section is positioned at described drive shaft sleeve 40.The driving section end face of described transmission shaft 20 is provided with the locking draw-in groove, and the end of described coder 30 is provided with and the joint pin 50 of locking the draw-in groove clamping.
In the present embodiment, the cross-sectional plane of the driving section of described transmission shaft 20 is gear-like.Purpose is to guarantee that transmission shaft 20 can drive drg 10 well.
In the present embodiment, described joint pin 50 is the regular hexagon that size is complementary with the cross-sectional plane of described locking draw-in groove.Purpose is to guarantee that coder 30 can be fixed on the driving section of transmission shaft 20 well.
The described elevator brake structure of present embodiment, the use of saving 30 of coder 30 connectors and coders has reduced material cost and manufacturing cost; Improve the service property (quality) of coder 30, reduced the damaged condition of coder 30 in installation process; Reduced assembly error, strengthened linking intensity, it is more firm that coder 30 is connected; Saved the installing space of coder 30.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
