Abstract
The utility model discloses a mine hoist depth signal sending set which belongs to a hoist lifting height signal sending set, and aims at providing a signal sending set with long service life and high precision. The mine hoist depth signal sending unit comprises a box body, a coupling shaft, a long shaft, a short shaft, cone gears, a pair of gears and a signal sending unit, wherein the coupling shaft, the long shaft and the short shaft are supported in the box body, the cone gears are fixedly on the coupling shaft and the long shaft and are meshed with each other, the pair of gears are fixed on the long shaft and the short shaft and meshed with each other, the signal sending unit consists of two encoders connected with two ends of the long shaft and is movably connected with a main shaft (1) by a connecting device, the connecting device consists of a drive plate (4) and a pin shaft (3), the drive plate (4) is fixed on the coupling shaft (5), and the pin shaft (3) is inserted in a drive groove of the drive plate and fixed on the end surface of the main shaft (1). According to the mine hoist depth signal sending set, the influence on the meshing of the cone gears caused by the deflection of the main shaft and the axial displacement is eliminated, the precision of the signal sending unit is improved, the service life of the signal sending unit is prolonged, the manufacturing and assembling precisions are lowered, and the mounting and the debugging are convenient.
Description
Technical field:
The utility model relates to a kind of sender unit, relates in particular to a kind of sender unit that can reflect the mine hoist up-down degree of depth.
Background technology:
As everyone knows, though present mine hoist is equipped with the depth signal sending set mostly; But be rigidly connected owing to be generally between the main shaft of the coupling spindle of this depth signal sending set and mine hoist; Not only make with assembly precision is had relatively high expectations, the Installation and Debugging inconvenience, and main shaft degree of disturbing and end float misalignment also can influence the conical gear correct engagement in the sender unit; Conical gear also possibly destroyed when situation was serious, and then influenced the precision and the service life of depth signal sending set.
Summary of the invention:
In order to overcome the defective that exists in the prior art, the utility model aims to provide a kind of long service life, mine hoist depth signal sending set that precision is high.
To achieve these goals, the utility model adopts following technical scheme: it comprises by casing, be bearing in coupling spindle and major axis and minor axis in this casing, be separately fixed on said coupling spindle and the major axis and intermeshing a pair of conical gear, be separately fixed on said major axis and the minor axis and intermeshing a pair of gear, two sender units that coder constitutes connecting with the major axis two ends respectively; This sender unit flexibly connects through connecting device and main shaft, and said connecting device is by being fixed on the coupling spindle and being provided with the dial of allocating slot, inserts in the said allocating slot and is fixed on the bearing pin formation of main shaft end face.
At least two of said allocating slot and bearing pins; Be with lining on the bearing pin.
Compare with prior art, the utility model has adopted the connecting device that is made up of dial and bearing pin owing to adopted technique scheme on the basis of conventional confguration, changed being rigidly connected between original main shaft and the coupling spindle into flexible connection; Therefore not only thoroughly eliminated main shaft degree of disturbing and end float misalignment to the influence of the conical gear engagement accuracy in the depth signal sending set, improved the precision and the service life of depth signal sending set, but also it is also very convenient to reduce manufacturing and assembly precision, the Installation and Debugging of parts.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: main shaft 1; Bearing seat 2; Bearing pin 3; Dial 4; Coupling spindle 5; Conical gear 6; Gear 7; Casing 8; Minor axis 9; Major axis 10; Coder 11; Coupling sleeve 12; Lining 13.
The specific embodiment:
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: main shaft 1 is bearing in the bearing seat 2 by tilting bearing, and this main shaft is connected with sender unit through connecting device.This sender unit by be fixed on casing 8 on the bearing seat 2, through bearing be bearing in coupling spindle 5 in this casing, respectively through bearing be bearing in major axis 10 and minor axis 9 in the casing 8, be fixed on conical gear 6 on the coupling spindle 5, be fixed on the major axis 10 with another conical gear 6 of this conical gear ingear, be fixed on gear 7 on the major axis 10, be fixed on the minor axis 9 with another gear 7 of this gear mesh, separately through coupling sleeve 12 be separately fixed at casing about in the of 8 two coders 11 on the side plate constitute, the input shaft of two coders 11 connects with the two ends of major axis 10 respectively through coupler separately; Said connecting device inserts by being fixed on the coupling spindle 5 and radially being provided with the dial 4 of two allocating slots, two ends that the other end constitutes through the bearing pin 3 that screw thread is fixed on main shaft 1 end face in the said allocating slot.For fear of wearing and tearing, in said allocating slot, be provided with sky and be enclosed within the lining 13 on the bearing pin 3.
Principle of work: main shaft 1 drives coupling spindle 5 through bearing pin 3 and dial 4 and rotates, and this coupling spindle drives major axis 10 through a pair of conical gear 6 and rotates, and this major axis drives minor axis 9 through a pair of gear 7 and rotates; So major axis 10 just passes to coder 11 with the rotating speed of main shaft 1 in the ratio of 1:1, the rotating speed of main shaft 1 is through showing with the ratio of minor axis 9 bonded assembly depth indicator (not shown)s in 1:1 simultaneously.
When main shaft 1 produced degree of disturbing, bearing pin 3 can radially slide in allocating slot, thereby can eliminate the influence of main shaft 1 degree of disturbing to conical gear 6 accuracy of meshs; When if main shaft 1 produces end float misalignment, bearing pin 3 can in axial direction slide in allocating slot, thereby can eliminate the influence of main shaft 1 end float misalignment to conical gear 6 accuracy of meshs.
