Abstract
A driving tooth 5 which is installed on the motor shaft 3 of the utility model is meshed with a planet tooth 6 which is fixed on a flange 4. The planet tooth 6 is meshed with a tooth of a concave inner wall of one end of a sleeve shaft 7 of a T-shaped gear, and a conical thrust bearing 8 is installed on the shaft of the other end of the sleeve shaft 7 of the gear. One end of a motor 1 is connected with the flange 4, and the excircle of the flange 4 conducts threaded connection with a casing 9 of a T-shaped gear box; the sleeve shaft 7 of the gear and the conical thrust bearing 8 are arranged in the casing 9 of the gear box, and a poker bar seat 10 is arranged on the other end of the motor 1. The utility model has the advantages of simple structure, compact structure, convenient manufacture, convenient installation, low cost, portable use, simple maintenance, low expense, etc. The utility model is a novel product which is worthy of being popularized and applied.
Description
The utility model relates to the rock drilling electric drill that a kind of mine excavation industry and building, highway, bridge foundation jewel hole use, and especially shows it is the rock drilling electric drill of coaxial inner conductor.
Using at present the rock drilling electric drill, adopt the different axle center with motor shaft of gearbox shaft (pricker axle), is a kind of eccentric mechanical transmission structure, unbalance stress, and operation is hard, while gear shaft use radial bearing, and be subjected to axial force, its unreasonable structure, weak point such as perishable.
The purpose of this utility model provides a kind of not only simple in structure, and to adopt the axle center of motor shaft and the axle center of pricker seat be the rock drilling electric drill of the coaxial inner conductor of coaxial inner conductor.
The purpose of this utility model is to realize like this, include motor, hand-held handle, motor shaft, pricker seat, driving tooth that its motor shaft is installed and the planet tooth engagement that is fixed on flange, parietal tooth engagement in the one end spill of planet tooth and T-shaped gear sleeve, on the other end axle of gear sleeve the circular cone thrust bearing is installed, one end connecting flange of motor, device has gear sleeve and circular cone thrust bearing, the other end that the pricker seat is arranged in the flange cylindrical T-shaped gearbox-case that is threaded, gearbox-case.
When the utility model uses, at first connect power supply and install drilling rod, during motor energising rotation, driving tooth is also along with rotation, and drive planet tooth and the rotation of gear sleeve, and be placed on the interior drilling rod of gear sleeve also along with rotation, be on the same axis owing to adopt motor shaft, gear sleeve, pricker seat three axle center, thereby stressed equal perseverance, use the circular cone thrust bearing simultaneously and bear axial compression.
Owing to adopt technique scheme, the utlity model has simple and compact for structurely, fabrication and installation are convenient, and are cheap, use lightly, safeguard characteristics such as simple expense is low.Renewal product is worthy of popularization.
Below in conjunction with implementing just to reach accompanying drawing the utility model is further specified.
Accompanying drawing is the utility model sectional structure schematic diagram.
Among the figure: the hand-held handle 3-motor shaft 4-flange 5-driving tooth 6-planet tooth 7-gear sleeve 8-circular cone thrust bearing 9-of 1-motor 2-nibbles roller box shell 10-pricker seat
As shown in drawings, gear-box 9 one ends have the motor 1, the other end that have hand-held handle 2 have pricker seat 10, in gear sleeve 7 and circular cone thrust bearing 8 are arranged, driving tooth 5 on the motor shaft 3 and planet tooth 6 engagements that are fixed on the flange 4.
