Abstract
The utility model provides a speed reducer, which comprises a motor, a box body of the speed reducer and a connecting flange, wherein both ends of the connecting flange are respectively connected with the motor and the box body of the speed reducer by fastening screws. Pins are also connected between the connecting flange and the box body of the speed reducer. Furthermore, the pins are positioned on the same circumference of the fastening screws and are symmetrically arranged at a clearance gap of the fastening screws. The utility model has the advantages that the original fastening screws are connected between the connecting flange and the box body of the speed reducer, and pins are also added. Then, the connecting strength between the connecting flange and the box body of the speed reducer is reinforced, and simultaneous, the looseness of the fastening screws between the connecting flange and the box body of the speed reducer can be effectively prevented. Consequently, the service life of the utility model is improved.
Description
Technical field
The utility model relates to retarder, particularly be the retarder of building hoist for building
Background technique
Include motor, reduction case, adpting flange at existing building with the structure that construction rises the machine retarder.The two ends of adpting flange are connected with reduction case with motor with fastening screw trip bolt respectively.Fastening screw trip bolt between adpting flange and the motor is exposed, and no matter changes, and still maintenance is all very convenient.But the fastening screw trip bolt between adpting flange and the reduction case is positioned at the bottom of peviform adpting flange inner chamber, in case occur becoming flexible, must pull down motor herein, takes out the coupling that is contained in the adpting flange inner chamber, could fastening again loosening screw.Existing structure, because the weight of motor itself is bigger, the factors such as vibrations of running in addition, the loosening of fastening screw trip bolt happens occasionally.Cause phenomenons such as structural damage, leakage of oil easily.Be fastenedly connected the fastening screw trip bolt between flange and the reduction case at the construction field (site), exist the space narrow, operation easier is big, incurs loss through delay defectives such as construction speed.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of fastening screw trip bolt of avoiding occurring between adpting flange and the reduction case to become flexible phenomenon, reduce maintenance, retarder with anti-vibration.
The technological scheme that solves the problems of the technologies described above is: a kind of retarder, and its structure comprises motor, reduction case, adpting flange; The two ends of adpting flange are connected with reduction case with motor with fastening screw trip bolt respectively, also are provided with pin between adpting flange and the reduction case and are connected, and pin is positioned at fastening screw trip bolt with on the circumference, and is symmetricly set on the gap location of fastening screw trip bolt.
The beneficial effects of the utility model are: the utility model between adpting flange and reduction case except original fastening screw trip bolt is connected, also increasing pin connects, can not only strengthen the join strength between adpting flange and the reduction case, can effectively prevent simultaneously the loosening of fastening screw trip bolt between adpting flange and the reduction case, improve working life of the present utility model.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 shows A-A partial sectional view in the pin key plan 2 between the utility model adpting flange and the reduction case; Fig. 2 is a B-B sectional drawing among Fig. 1.
As shown in the figure, the utility model provides a kind of retarder, and the structure of this speed reducer comprises motor 1, reduction case 6, adpting flange 5.The two ends of adpting flange 5 are connected with reduction case with motor with fastening screw trip bolt respectively, that is, be connected with motor 1 with fastening screw trip bolt 2, are connected with reduction case 6 with fastening screw trip bolt 3.Except being connected with fastening screw trip bolt 3, also be provided with pin 4 between adpting flange 5 and the reduction case 6, pin 4 is positioned at fastening screw trip bolt 3 with on the circumference, and is symmetricly set on the gap location of fastening screw trip bolt 3.Pin 4 shown in Fig. 2 is two.
Described pin 4 is taper pin with internal threads.Adopt taper pin with internal thread to be convenient to install and dismounting.This taper pin with internal thread can be selected the NBS part for use.
Below using process of the present utility model is described.
At first, the end with the adpting flange 5 of retarder is connected with reduction case 6 with fastening screw trip bolt 3.Again pin 4 is inserted in advance in the pin hole that adpting flange 5 and reduction case 6 are got, with in the taper pin with internal thread screw-in pin hole that inserts, adpting flange 5 closely is connected with reduction case 6 with threaded instrument.At last, the other end with adpting flange 5 is connected with motor 1 usefulness fastening screw trip bolt 2.
Claims (3)
1. retarder, its structure comprises motor, reduction case, adpting flange; The two ends of adpting flange are connected with reduction case with motor with fastening screw trip bolt respectively, it is characterized in that also being provided with pin (4) between adpting flange (5) and the reduction case (6) is connected, pin (4) is positioned at fastening screw trip bolt (3) with on the circumference, and is symmetricly set on the gap location of fastening screw trip bolt (3).
