Abstract

The invention discloses a ventilation cap. The ventilation cap comprises a ventilation cap body, filter elements and a connecting part. The ventilation cap body is provided with a first vent hole which communicates an inner cavity of a device with the outside atmosphere. The connecting part is provided with a second vent hole which is a stepped hole. The two ends of the second vent hole are communicated with the first vent hole and the inner cavity of the device respectively. The two ends of the connecting part are used for being connected with the ventilation cap body and the device in a sealed mode respectively. The stepped hole is gradually tapered from top to bottom. The filter elements are mounted at the step of the stepped hole. Accordingly, according to the ventilation cap provided by the present invention, by arranging the connecting part provided with the filter elements, liquid in the device is effectively prevented from overflowing through the ventilation cap; thus, the oil leakproof performance of the ventilation cap is improved. The invention further discloses a speed reducer comprising the ventilation cap.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a ventilation cap. The present invention also relates to a speed reducer comprising the above-mentioned breather cap. Background technique [0002] In devices such as reducers and transmitters, the temperature of the internal components of the box rises during operation, causing the air in the box to expand and the air pressure in the box to rise. For example, a reducer is a device that matches the speed and transmits torque between the prime mover and the working machine or the actuator. During the working process, when the reducer is running for a long time, the temperature in the box will rise, resulting in deceleration. The gas inside the machine expands. In order to avoid excessive pressure inside the reducer box and damage the internal components of the reducer, it is usually necessary to install a vent cap on the reducer to release the gas in the reducer and ...
