Abstract
The utility model discloses a brake end speed increaser relates to the water conservancy field, concretely relates to brake end speed increaser. Including the center pin, the mounting of rotors is in the center of center pin department, and the rotor both sides are equipped with interconnect's left casing and right casing, and left casing and right casing are connected and the inside cavity that surrounds the rotor that forms, the left side casing and the right casing outside are equipped with bearing retainer respectively, the last bearing that is provided with of bearing retainer, and the center pin is installed on the bearing, is equipped with water inlet and delivery port respectively on left casing and the right casing outer wall, is equipped with the ooff valve on water inlet and the delivery port, gear wheel, gear wheel and acceleration rate pinion intermeshing are installed to the center pin left end, the rotor intermeshing of brake in the side of gear wheel and acceleration rate pinion, in the teeth of a cogwheel of acceleration rate pinion and the brake. The utility model provides a water inlet water velocity of current brake become slow the time, the water velocity in the casing also can become the problem that causes measurement accuracy not high slowly.
Description
Technical field
This utility model relates to waterpower field, is specifically related to a kind of dynamometer end speed increaser.
Background technology
Dynamometer is output moment of torsion or the device of driving torque measuring machinery.If record the rotating speed of machinery simultaneously, also can calculate the output of machinery or drive power.Dynamometer is mainly used to measure the shaft power characteristic of the machineries such as electromotor, motor, internal combustion engine, gas turbine and pump.Some dynamometer had both can absorb the mechanical energy of tested machinery and had measured its output, can release again the driving power of energometry machinery.Dynamometer has mechanical type, hydraulic, electric power type and electric vortex type.
Chinese patent literature CN203837854U discloses hydraulic dynamometer, this patent good cooling results, and test scope is big.But the when of the water inlet low water velocities of this patent, the water velocity in housing also can be slack-off thus cause certainty of measurement the highest.
Summary of the invention
This utility model provides a kind of dynamometer end speed increaser, and the when that this utility model solving the water inlet low water velocities of existing dynamometer, the water velocity in housing also slack-off can cause the problem that certainty of measurement is the highest.
For solving the problems referred to above, this utility model adopts the following technical scheme that dynamometer end speed increaser, and including central shaft, rotor is arranged on the center of central shaft, rotor both sides are provided with interconnective left shell and right shell body, left shell and right shell body and connect and be internally formed the cavity surrounding rotor；Being respectively equipped with the support of bearing outside left shell and right shell body, the support of bearing is provided with bearing, central shaft is installed on bearing, left shell and right shell body outer wall is respectively equipped with water inlet and outlet, water inlet and outlet and is provided with switch valve；Central shaft left end is provided with gear wheel, and gear wheel gear little with speedup engages each other；Dynamometer is in the side of the little gear of gear wheel and speedup, and the gear teeth of the little gear of speedup engage each other with the rotor in dynamometer.
Advantage of the present utility model has: certainty of measurement is high, improve work efficiency, the flow restoration of water can be allowed to be operated to normal value with this by speeder low water velocities when.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Symbol description in figure: central shaft 1, rotor 2, left shell 3, right shell body 4, the support of bearing 5, bearing cap 6, bearing 7, water inlet 8, outlet 9, valve 10, gear wheel 11, the little gear of speedup 12, dynamometer 13.
Detailed description of the invention
By optimal embodiment, this utility model is described in detail below。
As it is shown in figure 1, dynamometer end speed increaser, including central shaft 1, rotor 2 is arranged on the center of central shaft 1, and rotor 2 both sides are provided with interconnective left shell 3 and right shell body 4, left shell 3 and right shell body 4 and connect and be internally formed the cavity surrounding rotor；Being respectively equipped with the support of bearing 5 outside left shell 3 and right shell body 4, the support of bearing 5 is provided with bearing 7, central shaft 1 is installed on bearing 7, and bearing 7 coordinates with bearing cap 6；Being respectively equipped with water inlet 8 and outlet 9, water inlet 8 and outlet 9 on left shell 3 and right shell body 4 outer wall and be provided with switch valve 10, switch valve 10 controls the turnover of water and prevents the overflow of water.Said structure is essentially identical with background technology patent structure.Inventive point of the present utility model is: central shaft 1 left end is provided with gear wheel 11, and gear wheel 11 gear little with speedup 12 engages each other；Dynamometer 13 is in the side of the little gear of gear wheel 11 and speedup 12, and the gear teeth of the little gear of speedup 12 engage each other with the rotor in dynamometer 13.Carry out speedup by pitch wheel, then tested the speed by dynamometer, improve the degree of accuracy tested the speed.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating this utility model example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection domain of the present utility model among.
