Abstract
The invention discloses a planet speed changing box for a ground grinding machine. The planet speed changing box comprises planetary wheels, sun wheels, annular gear rings and a planet carrier, wherein the planetary wheels are arranged on the planet carrier through a pin shaft; and a planet carrier bearing is arranged between the box body and the outer end part of the planet carrier. The planet speed changing box further comprises a seal ring of the planet carrier bearing which is arranged on the planet carrier; and a seal lip of the seal ring of the planet carrier bearing is contacted with the outer ring of the planet carrier bearing to form a sealing interface. Outer rings of the bearing and a shaft sleeve are utilized as the sealing interface of the seal ring; in the aspect of specification selection, the sealing ring achieves the minimization; the seal contact surface has high finish, the calorific value caused by frication is small, one end of the bearing is exposed to the outside, so that heat can emit to the outside through the bearing, the temperature variation and pressure variation in the box body are small, internally pressing impact to the seal lip of the sealing ring is small, good sealing effect is achieved, and lubricating grease difficultly seeps out; and the seal contact surface is small, the processing cost is low, and the planetary wheels are made of nylon materials, so that noises are greatly reduced.
Description
Technical field
The present invention relates to the floor grinding machine technical field, especially relate to a kind of floor grinding machine planetary transmission.
Background technique
Floor grinding machine is a kind of device for floor wax, cleaning, is mainly used in civil area, and machine requirement compact structure, volume are little, lightweight, noise is little when using.Wherein, planetary transmission is the floor grinding machine vitals, has determined the performance of floor grinding machine.
There is following problem in disclosed floor grinding machine planetary transmission at present: it is inboard that the seal ring of existing planetary transmission is fixed on the planetary transmission cap, the seal lip of seal ring and planet carrier circumferential surface form the seal interface, it is external that upper planet frame bearing is located at the closed box that seal ring, housing, cap form, during gearbox work, the seal ring place is difficult for heat radiation, the casing temperature rise is excessive, airtight casing air expands, pressure raises, high pressure produces larger interior pressure impact to the seal lip of seal ring, seal failure, lubricating grease easily oozes out, to environment; The seal interface is high to required precision, and the planet carrier component size is large, and processing cost is high; Noise is large during operation, and is very high to precision and the correction of the flank shape requirement of gear, generally can only be controlled at 70dB, and comfort is poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of floor grinding machine planetary transmission, and heat easily sheds in its planetary transmission, and sealing effect is good, and lubricating grease is difficult for oozing out outside the casing.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of floor grinding machine planetary transmission, comprise planet wheel, sun gear, ring gear, planet carrier in the casing, described planet wheel is located on the planet carrier by bearing pin, be provided with the planet carrier bearing between described casing and the planet carrier outer end, also comprise planet carrier bearing seal ring, described planet carrier bearing seal ring is located on the planet carrier, and the seal lip of planet carrier bearing seal ring contacts with the outer ring of planet carrier bearing and forms the seal interface.
Be provided with sun gear bearing and sun gear seal ring and sun gear axle sleeve between described sun gear outer end and the planet carrier, described sun gear seal ring is located on the planet carrier, and the seal lip of sun gear seal ring contacts with the outer ring of sun gear axle sleeve and forms the seal interface.
Described planet wheel adopts nylon material.
The transverse tooth thickness of described planet wheel standard pitch circle is 1.2-2 times of space width.
The present invention compared with prior art, have the following advantages: seal ring is installed on the planet carrier, with the seal interface as seal ring, the outer ring of bearing and axle sleeve, the seal ring specification selects realization to minimize, sealing contact surface is highly polished, the caused heating value that rubs is little, and bearing one end is exposed to the outside, heat can be by bearing to external cooling, make the interior temperature and pressure of casing change little, the interior pressure of the seal lip of seal ring is impacted little, reach good seal action, lubricating grease is difficult for oozing out; Sealing contact surface is little, and processing cost is low; Planet wheel adopts nylon material, makes and the sun gear of its engagement, the engagement that ring gear forms " steel-nylon ", and noise is than the low 10-12dB of " steel-steel " engagement.
